General description
HBot 3D is a modern 3D printer with one of the largest working area available on the
market. Big rigidity and reliable elements of linear motion technology make high speed of
printing with very good quality and accuracy possible.
Closed cover, big working area, authorial electronics and software make a reliable product,
which may become a crucial component of your workshop even today. You can create
models of buildings and architectural models quickly and infallibly, you can materialize your
visions and present them instantly to your clients.
The manual is subject to certain update limitations related to printing process and
distribution. The most up-to-date version of the manual is always available on producer’s
website:
http://3d-printers.pl/downloads/HBot3D-manual-en.pdf.
Before using a product please read the newest version of the manual.
1.1. Functions
Hbot 3D is dedicated to building physical objects directly from 3D documentation made with
CAD tools. Capabilities of additive manufacturing, which is also called ‘3D printing’, might be
invaluable help while working at home, in the office, workshop or in a factory. 3D printing is
a technology which allows to build 3D objects economically and without the need of
additional gear and machining tools.
FFF (Fused Filament Fabrication) technology has been used in a device. It utilizes polymers as
a base material to build 3D objects. One of the advantages of the technology is that there is
a quickly expanding group of materials which, besides standard materials such as PLA and
ABS, contain composite material. Due to a growing number of materials, 3D printer users
are able to build objects which may be treated as prototypes but also as functional
elements. One of the largest working area on the market and a closed chamber sustaining
stable working conditions make Hbot 3D a very attractive offer for either professionals or
amateurs.
1.2. Safety
While using a device basic safety measures should be taken.
Remember:
- The device has EIC protection class 1 and has to be always connected to electricity
network with a functional PE protective joint (ethernet socket with a protective pin). It is
forbidden to use a device without meeting the condition, as in case of a breakdown it may
cause electric shock!
- Do not touch device’s hot-end during work as it reaches really high temperatures (above
200 °C). Contact with a heated head may lead to serious burns.
- Do not touch heated platform during work.
- Do not use a printer when a working chamber is open during work, as direct contact with
moveable elements may cause a trauma or serious injuries.
- During manual lifting of a working table (with the use of device’s control panel or YARRH
program) it is necessary to exercise utmost caution. A user must pay attention and
prevent a hot-end or XY-axis carriage from hitting a model being printed and located
underneath.

2. The first start
2.1. Unpacking
Put the box with a device on even ground. Open the upper cover of the box and bring out
printer’s pieces of equipment located in the compartment of the upper part of protective
foam. After bringing them out, protective foam might be removed. On device’s side panels
there are carry handles. With another person’s assistance, grab handles of both sides of the
printer and bring the device out of the box (Attention: the printer weighs 25kg!) and put
gently on the ground. At the bottom of the device there will be protective foam. Grab the
printer by the handles again and raise it up slightly. The second person should remove the
bottom part of protective foam. After completing all of the above the printer should be put
in a destination working spot.
2.2. Connecting to power supply network
Two wires are connected to the device. One of them is the power cord and the other is to
connect the device with a computer using USB interface. During the first start it is enough to
connect the device to power supply as a trail 3D printing is done with the use of a file from
the attached microSD card.
Following the steps will help to complete it:
STEP 1
The power socket is located on the back side of the device.
STEP 2
Before connecting power supply make sure that the switch – next to the power socket – is
on ‘off’ position.
Bring the power cord out of the box and connect it to a socket with a proper end.
Connect another end to the power socket.
STEP 3
Now when the device is connected to the network put the power switch on power position
1.
STEP 4
On the control panel, power button’s backlight should be pulsing.
2.3. Working platform leveling
Providing a proper level of the platform in relation to the printing head is crucial to obtain
printouts of a high quality. Before the first start of the device, the fol lowing calibration
should be made. 3D Printers company tests and calibrates every printer at the end of a
production process. However during transportation, head’s position in relation to the table
might be somehow relocated and that is why the following procedure must be completed.
STEP 1
Put the power switch on power position 1.
STEP 2
Turn on the device with Power button on the control panel.
STEP 3
Open the front door of the printer. Between X-axis carriage and the working table there is
printing head’s protective foam. It needs to be removed before leveling the platform
(Attention: remember to get to know printer’s coordinate system before leveling the
platform).
To complete it enter the menu using OK button on the panel. In the printer’s menu select
Jog, then 10mm Movm, and at the end Z MovementMovollowing actions are to be
confirmed with OK button. The operator panel, for moving the working table in relation to
the working platform, will display. ATTENTION: To move the table away from the head, the
upper arrow must be pressed!. At that moment the working table will move away fromorm
the head by 10mmrotective foam can be removed now.
After removing protective foam, the working platform leveling can be started. Following the
steps will help to complete it:
STEP 4
Enter panel’s menu and place the carriage with the head in the left corner in front of the
device.
To do it enter the menu pressing OK button on the panel. Then, using arrows, select Prepare
position from the list and confirm it with OK button. Next select Home All Axis confirming
with OK button.
The carriage with the head will move to the left front corner of the device and the table with
the working platform and the head will reach the minimal position.
STEP 5
The width of the aperture between the head and the working table should be of 0.1 mm.
The measurement of the aperture should be done by putting the attached template, a feeler
gauge with a 0.1 mm sheet or a thin sheet of paper between head’s nozzle and working
table’s surface.
If there is no resistance or there is no possibility of putting the template between the nozzle
and the working table, the width of the aperture between nozzle’s exit and the working
platform must be adjusted.
To do it turn the platform positioning screw in the corner on which the head is at the
moment (to move to another corner proceed to STEP 6). Clockwise or counter clockwise
turn of the screw makes the platform go up or down.
STEP 6
Setting appropriate distance between head’s nozzle and the working platform must be
repeated for every corner of the platform.
To do it enter the menu by pressing OK button on the panel. Select Prepare form the menu,
and then use down arrow to move to the last position on the menu and select
motorMotorsonfirming with OK button. At that moment kinematic components of the
printer can be moved manually (Attention: Moving elements manually must be done
slowly!)
With the motors off, move the carriage manually to every of four corners of the worki ng
platform. For each of the corners repeat the procedure from STEP 5.
To check whether the platform’s level is set properly leveling procedure can be repeated
(STEPS 4-6)
After completing all the steps the working platform is ready to work.
2.4. The first installation of the reel with working material
To get to know how to perform filament’s first installation on the head see 5.4.
2.5. Trial 3D printing
To check whether the device works properly, before connecting to a computer, make trial
construction of a test element.
If you completed the instruction from 2.1. – 2.4. constructing a test element can be started.
Following the steps will help to complete it:
STEP 1
Make sure that: the device is connected to a power supply, the device it is mobile, the
working platform Is leveled properly.
STEP 2
Make sure that the working surface of the platform is prepared for printing. Platform’s
printing preparation is described in 5.1.
STEP 3
Select Play in the main menu. Select sd from the list. The list of files which are on a memory
card will display. Select test_ABS.g or test_PLA.g from the list. Depending on the type of
material (ABS or PLA – one of these is on reel’s label) included in the set select a proper
position in the menu. At that moment the head and the working table are reaching
temperatures set before. Heating process can be observed on the screen. When the proper
temperatures of the head and working tables are reached, printing process starts
automatically.
If all the steps are completed, element’s construction should start. Test model printing
should take approximately 50 minutes.
When the model is printed, remove it from the working table following the instruction
from 4.9.
3. YARRH package
3.1. General description of a package
Hbot 3D is delivered with YARRH control software. YAARH package is used to control the

3 Temperature graph
4 Manual axis homing and extrusion control panel
5 Graphical representation of printed object
6 Manual axis movement panel
Open GCODE – when selecting it we can open a previously generated file, ready to be used
in the model construction process. After selecting this position Windows Explorer displays a
window to choose file’s location. Such a file can be generated with YAARH from the STL file.
The process of generating a GCODE file is described in chapter 4.
GCODE file can be generated in other available environments but it should be considered
that 3D Printers Sp. z o.o. does not guarantee the quality of object’s construction process
which is performed on the basis of files generated outside YAARRH environment. YAARRH
environment is provided together with configuration files adjusted to the material delivered
by printer’s producer. By using it, the optimal parameters of printouts will be obtained.
The producer is constantly working on optimization of software configuration and adjusting
it to delivered material parameters. In case of YAARH configuration changes, the program
will update automatically after its start, providing that the computer has the internet access.
Remember that using GCODE file from different source may cause device’s malfunctions
and element’s damages.
Open STL – enables opening the STL file. A detailed description might be found in 4.3.
Connection
There is a possibility of making a remote connection with the device with the use of LAN. To
do it connect both the device and a computer to the same local LAN. With this solution the
need for a computer working close to the device is eliminated. After connecting the device
to LAN, the address of the network displays on the main screen of the front panel
This address must be typed in the window displayed after pressing Ethernet Connection in
Connection bookmark.
Settings
In this bookmark there is Options being quite important for the user.
Options – after clicking this position with a left mouse button the window displays – basic
changes related to YARRH environment might be done.
Extruder's number – in case of Hbot 3D there is one extruder at disposal, and that is why
default value '1' should not be changed.
Auto-update – by selecting this option the software will be automatically updated during its
start. Such a solution enables the user to have updated version of both the software and
configuration files for printing with the use of materials provided by the producer.
Printer – in this section the size of working area can be defined. For Hbot 3D, default values,
visible on the screenshot above, should remain unchanged.
Look – in this section YARRH interface font can be changed
Slic3r –in this section, location tracks of Slic3r are given. This program supports YARRH
environment and configuration files work. The tracks shouldn't be modified by
inexperienced users.
ATTENTION: In YARRH package 'cutting' Slice3r software is used. It is available and
distributed as open source. Printer's producer - 3D Printers sp. z o. o does not take direct
responsibility for errors and imperfections related with the use of this program. We do our
best to test software version together with YARRH package in relation to Hbot 3D, and to
make configuration file of the program allow to use all printer and exploitation material's
(filament’s) possibilities.
3.5. Connecting a device to a computer with the USB cable
USB port of the device is located on its backside wall in the bottom left corner.
USB cable is attached to the set and must be connected to device's socket. The other end
must be connected to computer's USB port. The USB cable has different plugs on each of its
ends – one fits printer's USB socket, the other fits computer's USB socket.
The device should be detected by the computer.
After running YARRH package in the bottom part of the screen – on the left – there should
be the icon representing USB port and confirming that the printer is properly connected to
the computer and visible to YARRH.
3.6. ETHERNET connection with a device
Connection with the device can be also made with the use of ETHERNET port. It might be
either with a wire or wireless with the use of WiFi (in that case an additional WiFi router, not
being the part of default equipment of the device, is needed).
The following steps help to make a network connection with the device:
STEP 1
Using the Ethernet cable, connect the device with the network which will be used
STEP 2
Start YARRH package. Enter the toolbar and select Connection and then Connect Ethernet.
STEP 3
When the window displays, type IP address of the device. If the device is connected to the
network properly in the main menu panel a current IP address displays. Put the address in
YARRH window and confirm with OK. IP address dedicated to the printer should be
configured before in LAN to which the printer will be connected. To configure the address
contact LAN administrator. To use Ethernet connection, make sure that it is activated in
config.txt on printer's disk and that IP address was typed correctly. It can be checked in the
network settings section of the file.
See the example below:
# network settings
network.enable true # enable the ethernet network services network.webserver.enable true # enable the webserver
network.telnet.enable true # enable the telnet server
There are two options of Ethernet connection. Automatically – with the use of dhcp. The following values must be typed: network.ip_address auto # use dhcp to get ip address
Or permanent address: network.ip_address 192.168.1.222 # the IP address network.ip_mask 255.255.255.0 # the ip mask network.ip_gateway 192.168.1.1 # the gateway address
After connecting with the device the buttons controlling axes and temperature will be
activated, in the bottom part of the screen LAN icon should be visible.
4. 3D printing preparation 3D model preparation with the use of modeling
software
3D printing which uses FFF technology has some limitations. When designing elements for
3D printing these limitations must be considered. Below there are tips that may help to
make models being designed fulfill technological requirements.
The minimum gauge of element’s partition is limited by printing head’s
diameter, which is 0,4mm for Hbot 3D
The maximum pitch angle of model’s walls might be 45°. To build elements of
higher pitch, they should be constructed with supporting structures. To
read about generating of supporting structures - see 4.4.
Model’s base should be flat so that model’s first layer can stick to the working
platform.
If a model are made with the use of surface-modeling-based software,
objects should be made in a way so created surfaces make a closed chunk.
If a model is built from bigger number of surfaces, surfaces shouldn’t
intersect. In other case there may be errors in a generated STL file on the
basis of which printer’s control commands are created afterwards. To
read about possible errors of SLT screens see 4.2.
4.2. STL file verification
A proper selection of triangle screen is a very important procedure wile generating STL files.
This stage should be completed with the utmost care - pay attention to parameters such as
triangle screen’s density, which depends on selected latitudes, or proper construction of a
screen.
Special tools such as NetFabb (available on http://www.netfabb.com/) should be used to
verify proper construction of a triangle mesh.
It is a very important activity as triangle mesh errors may cause incorrect construction of a
model.
Common errors for triangle screens are:
Intersecting triangles
Unclosed walls/surfaces of a model
4.3. Loading STL file to YARRH and 3d object manipulation
STL is a standard format used in 3D printing. Most of 3D modeling programs allow to save a
model in this format
To open STL file in YARRH select File and Open STL. After selecting Open STL, find file’s
location with the use of displayed Windows Explorer window. After selecting a file, the
window for preparation the files to construction displays.
4.3.1 STL manipulation widnow
After selecting Open STL in File menu the window for STL manipulation opens.
File preparation interface elements
1 Slicer options – the panel for configuration of parameters of the object to be
constructed
2 Object manipulation – the panel of tools for object manipulation on the
platform
3 Export – the panel for generating machine codes and STL files
4 Table preview – the panel showing a current position of the object on the
working platform
4.3.1.1 Slicer options
Slicer options section regulates printing parameters. Configuration files are prepared for
basic materials provided by printer’ s producer. Select from the Config. list. To find out more
see 4.4.
4.3.1.2 Object manipulation
Additional objects can be open with Open File button.
X and Y fields
The beginning of coordinate system, for graphic area and for the working platform, is in the
left front corner. It corresponds with the point of coordinates X,Y,Z<0,0,0> in printer’s
coordinate system.
Y-axis is directed towards the back wall, and X-axis towards the right wall of the device. Z-
axis is directed upwards.
X i Y fields allow to define the position of the central object in a specific place of the working
area.
Scale allows to scale the object. Scaling is expressed as a percentage of the original sizes.
Rotation allows to rotated the object in relation to vertical Z-axis. Rotation is expressed In
degrees of rotation.
Height, Width and Length represent object’s maximum sizes in three dimensions. Graphic
icons visible on the right side of Object manipulation section allow to perform the actions
described in the table below.
Pointing the object in the working area
Selecting multiple objects
Deleting objects from the working area
Manual positioning the object in the working
area
Object’s secular reflection on axis X, Y or Z
Copying the elements in the working area
4.3.1.3 Export
In this section there are two options:
GCODE – the option allows to export the object, which was previously set in the working
area, to the GCODE file. The file in this format contains the list of command for executive
elements of the device. While GCODE file generating, the location of the file is to be
determined.
STL – the option allows to generate a file containing more than one object, in STL format.
This tool is useful in case when the prepared working platform contains a lot of objects
whose configuration will be used many times during subsequent construction processes.
Saved positions of objects from STL file can be later opened in YARRH. Thanks to this option
we can generate GCODE files with the use of various parameters (layer’s height and
efficiency of space filling) of the objects made or various materials which require selection of
a distinct configuration of construction parameters.
4.3.1.4 Table preview
In Table preview graphic area, a virtual representation of the platform is visible. It allows to
see object’s exposure preview.
The working area manipulation operations:
rotating the working area about three axes by clicking and holding the right mouse
button and moving the mouse
zooming in and zooming out the camera in relation to the working table with the use
of mouse’s scroll
moving object on the working area by pointing it with the mouse’s cursor
Additionally, there is a possibility of turning on one of three views of the working area with
the use of the buttons located directly above the table preview area.
There are following views’ exposures:
Front –the front view of the platform
Side – the side view of the platform
Top – the view of the platform from the top
4.4. Print parametres selection
Printing parameters are configured in Slicer’s options section in STL files manipulation
window. Configuration files are initially prepared for basic materials provided by the
producer. Selection should be made from Config. list. 3D Printers company regularly updates
configuration files, willing to constantly improve the quality of printed models. In case of
configuration parameters change YARRH updates automatically during the start. To update,
make sure the computer on which the program was installed has access to the Internet. By
selecting appropriate default Config, we make the device work using standard parameters.
The user can change some YARRH parameters. These are: Layer height, Infill and Support.
Layer height defines the height of a single layer of the model being constructed. This
parameter influences the quality of model’s surface and that is why its value can be changed
in relation to model’s function. Recommended range in which changes can be made is 0.10
– 0.30 mm. 0.20 mm is a standard value providing outer surfaces of a high quality. Standard
value of layer height is 0.20mm and it should ensure high quality of print. When a high
quality of mapping is not necessary in outer surfaces, the height of a single layer can be
increased. It will speed up the printing but with a significant pitch angle of model’s outer
walls it may cause aliasing higher.
Infill is a parameter defining the efficiency of space filling of the object. 40% is a standard
value which provides a good construction result with material efficiency, objects low mass
and, what is related to it, decrease in working material consumption. The user can change
the value of this parameter in relation to endurance requirements for the model
Support – is the additional option which allows to generate supporting structures. They may
be needed when the objects being built has outer surface of the substantial deviation from
the vertical. Selecting option ‘Support’ allows to support overhang elements of the model.
Additionally generated structure is easy to break. Sometimes the model built with the use of
supporting structures requires additional processing of supported surfaces.
4.5. GCODE file generating
When elements’ preparation on the working platform is completed, to print them we have
to go through the process of printing head’s GCODE instruction file generating. This process
converts STL to GCODE. GCODE file contains printer’s list of instructions.
Following steps will help to complete GCODE file generating:
STEP 1
In YARRH select File, which is in the left top corner of the window. Select Open STL from the
list and from the disk choose the file with a model to be printed. A new window with the
object in the working area, reflecting device’s real area, displays.
STEP 2
With the use of the tools available in the window, orient the model in the working area
according to your preferences. After placing a cursor on a particular tool its short
description displays.
STEP 3
From Config. list select proper configuration adjusted to currently used material.
STEP 4
In the window of STL manipulation, in Export section select ‘GCODE’ to convert. After
clicking it, the window, in which the target folder is to be chosen, displays. The target folder
as well as file’s name cannot contain Polish characters. After clicking Safe the program starts
generating printing head’s tracks. This process may take from few second to 20 minutes or
more, depending on the size and complexity of STL and computer efficiency.
When GCODE instruction lists have been generated correctly, 3D model of the prepared
object sliced into layers and head’s tracks, is automatically opened by YARRH.
4.6 GCODE verification
Using YARRH you can check whether the GCODE file has been generated correctly. To do so,
use the scroll bar on the right side of the window with a 3D object. Scrolling it you can
analyze the whole model layer after layer.
A layer being currently analyzed is highlighted red, the rest of the model is highlighted grey.
The line represents the track along which the head will be moving. If you notice that the
head is moving In the space not connected with the model or supportive structures, see
4.1.and 4.2. to verify the model. After checking and correcting it, open the file again and
generate GCODE from the beginning. 3D model print with the use of a computer
After generating and verifying GCODE file, we can proceed to 3D model printing.
STEP 1
Make sure that the device is connected to the power and turned on, that YAARH has been
stared and is correctly connected with the printer (see 3.5).
STEP 2
Make sure that the surface of the working platform is properly prepared for the printing.
Preparation of the working platform is described in 5.1.
STEP 3
From the main panel select Print (left top corner of the main panel).
If all the above has been completed, building of the model starts. 3D model print from
SD card without the use of a computer
Hbot 3D allows to print without the use of a computer.
To print without the use of a computer, follow the steps below:
STEP 1
Open My computer folder. From the list of devices and external disks select removable disk
which represents the contens of the SD card installed in the printer.
STEP 2
Copy previously generated GCODE instruction file to the folder mentioned above.
STEP 3
When the copying is finished, you can disconnect the computer from the printer.
STEP 4
Make sure that the surface of the working platform is properly prepared for printing.
Preparation of the working platform is described in 5.1.
STEP 5
From the main menu select Printout. Select sd. From the displayed list, select the file
defined beforehand. At that moment the head and the working table are reaching
temperatures set before. Heating process can be observed on the screen. When the proper
temperatures of the head and working tables are reached, printing process starts
automatically.
If all the above has been completed, building of the model starts.
4.9 Print finalizing, removing a model from a working platform
When the device finishes building of the element, remove it from the working platform.
Following the steps below will help to complete the process:
STEP 1
To make the access to the model easier, using Jog from the control panel (see Błąd! Nie
można odnaleźć źródła odwołania.) move away the working table and put it in a
convenient position.
STEP 2
Prepare a flat spatula with a thin blade.
STEP 3
Using a spatula, pry a built-in element at the edges of the base to gradually separate object’s
base from the working platform.
STEP 4
If the object sticks tightly to the working platform, wait until its working area temperature
decreases below 30°C. It will make the object easier to remove.
STEP 5
If the object sticks tightly to the working platform, remove working platform glass from
printer’s chamber and slowly pry elements’ edges outside the device.
4.10. Finishing processing of a model
In most cases printouts do not need any additional processing. Models that were
constructed with supporting structures are exceptions. To remove them you need to break
them. Be careful not to damage the main part of the printout. Supported elements may
need some additional processing such as cutting to remove all supports’ residues.
If necessary objects made of ABS can be additionally cut or bathe in acetone vapors, which
may help to smoothen the surface and reduce the visibility of printout’s individual layers.
5. Exploitation activities Changing the tape being a coverage for the
working area of the table
Printer’s working platform is made of boro-silicon glass covered with adhesive tape made of
Kapton. The tape is used to provide adhesion of models to the surface of the working table.
To make sure the adhesion Is proper, the working platform surface has to be examined
before each printing. If the tape of the Kapton tape was damaged, its bad part should be
replaced.
Additionally, 3D Printers recommends using so called ABS Juice. There is a packet with ABS
pellet attached to every printer. To make ABS juice, the packet content is to be mixed with
500ml of acetone and allowed to fully dissolve.
The following steps will help to complete the process of working table surface preparation:
STEP 1
Make sure that table’s heating is turned off and its temperature is below 30°C.
STEP 2
Bring the working glass out of printer’s chamber and slowly place it on the flat surface of the
table.
STEP 3
Remove the old tape and clean and degrease the glass surface. Wait until it is dry or mop it
dry.
STEP 4
Stick a new tape carefully not to leave air bubbles between the tape and the surface.
STEP 5
If you want to achieve even higher adhesion of a model to the platform, mop the surface of
the working platform with a cloth soaked with ABS juice. To make ABS juice, the packet
content is to be mixed with 500ml of acetone and allowed to fully dissolve. Using the
solution, lubricate the working platform covered with the Kapton tape, especially on the
spots where the previous model adhered before and where adhesive ABS layer has been
peeled back while removing the printed model from the platform.
STEP 6
The platform is ready to be re-used.
5.2. ension regulation of an XY axis belt drive
The stretching force of XY axis toothed belt, after some time of exploitation, may be
decreased. To provide high quality of prints, its stretching force should be improved from
time to time.
To do it, follow the steps below:
STEP 1
Make sure that table and head’s heating is turned off and their temperature is below 30°C.
STEP 2
To do it enter the menu pressing OK button on the panel. Select Prepare from the list and
then Motors off confirming with OK button.
STEP 3
Prepare the following tools: 8mm wrench and 4mm allen key.
STEP 4
Loosen all 4 screws of the left and right motor in the same way as it is shown in the picture.
STEP 5
After loosening the screws, firmly press motor’s main body towards printer’s back cover
(same way as in the picture) to obtain substantial belt tension.
STEP 6
With the motor pressed, tighten all the screws to make the motor stable.
STEP 7
To measure belt tension grab the belt in the middle part of X-axis and pull it towards you.
The belt with a proper tension, with the motors off (see Błąd! Nie można odnaleźć źródła
odwołania.), should bend by about 2cm, and then cause the movement of the carriage in
your direction.
STEP 8
After tightening all the screws the toothed belt should obtain significant tension. If it
doesn’t, repeat the procedures from STEPS 4-6 for the opposite motor.
5.3. Cleaning and lubrication of a printer
To avoid problems while using the device and to obtain high quality of prints, the printer’s
working chamber should remain clean. It is recommended to clean the chamber using a
vacuum cleaner of a soft-brush-ended pipe. Neither detergents nor water should be used.
Linear elements need regular lubrication. Small amount of grease should be put on linear
guides (rollers of X, Y and Z axes). It should be spread with the use of a dry cloth. The
remaining amount of grease is to be spread during device’s work.
Printer’s coverage outside parts should be cleaned with a soft moist cloth. It is forbidden to
use solvents, especially acetone, which may damage the surface of varnish, cover’s plastic
and device’s doors.
5.4. Loading a printing material
Reel of material (ABS or PLA) has been attached to Hbot 3D. The reels are labeled (back side
of the reel) and wrapped in thermo-retractable foil. Before starting the device, insert the
filament into printer’s head. When inserting the material for the first time, or when replacing
the material with a new reel of the same type (ABS with ABS, or PLA with PLA), follow the
instruction below.
If you want to change the type of material (ABS for PLA, or PLA for ABS) see 5.5.
The following steps will guide you through the software installation process:
STEP 1
Remove the protective foil form the reel with the material.
STEP 2
Open the working chamber of the device. At the bottom of the chamber there is an oval
element which is used to position the reel in the working chamber.
STEP 3
Place the reel so the positioning element is in the inside hole of the reel and filament
unwinds same way as in the picture.
Start inserting the filament into a Teflon guiding pipe and continue until you feel resistance.
At that moment filament reaches extruder’s block.
STEP 4
In extruder’s block there is a lever with a bearing which presses the filament towards
extruder’s tracing wheel.
Push the lever to insert the filament between the bearer and extruder’s tracing wheel. Push
the filament until it end will be between bearing and hobbet wheel.
STEP 5
Turn on the device and enter the menu; select Prepare. From the list select Pre Heat ABS or
Pre Heat PLA, depending on the material type included in the set.
The device starts to heat the head and the hot bed. Since then under no circumstances do
not touch the working area of the table (glass and heating element) or the printing head.
STEP 6
Make sure that there is a certain distance (10mm or more) between the working platform of
the device and the printing head. It allows to press the material freely.
If there is no proper distance, enter printer’s menu by pressing OK on the panel. In the
printer’s menu select Jog, then 10mm Movm, and at the end Move Z– the following actions
are to be confirmed with OK button. The operator panel, for moving the working table in
relation to the working platform, will display. To move the table away from the head, up
arrow must be pressed! At that moment the working table will move away from the head by
10mm.
STEP 7
The current temperature of the head and the platform is displayed on the screen. When the
temperature reaches the desired level, select Prepare from the menu and then Extrude from
the list. In the next menu there are two options to choose and Extrude 5mm should be
selected. A single press causes a slight turn of extruder’s tracing wheel and filament’s
movement into the head. Extrude 5mm should be pressed regularly until there is an even
outflow of the material from the nozzle. If after substantial period of time, the plastic thread
coming out of the head is not seen, check whether the filament is properly being inserted
into the head – to do so observe the tracing wheel and the clamping bearing of the extruder.
While selecting Extrude 5mm option, the filament should be in the position between the
bearing and the tracing wheel. If you still have a problem with inserting the filament into the
head, see 6.2.
STEP 8
Remove extruded material from head’s estuary using tongs or tweezers so it wont disturb
device’s work. Attention : The material should not be removed without the use of tools
(head’s temperature is over 200°C) as it may cause burns.
At this moment the material is properly inserted into the device’s head.
5.5. Changing a printing material
When changing the material type , PLA for ABS, or ABS for PLA, we always use the same
procedure. Always use the temperature similar to the working temperature of the material
of higher temperature, that is, the temperature for ABS.
STEP 1
Turn on the device and enter the menu. Select Prepare from the list. Select Pre Heat ABS
from the list.
STEP 2
Wait till the head reaches set temperature. After that, proceed to the next step.
STEP 3
Pressing Retract remove the filament from extruder’s block. To use this command enter
Main Menu of the panel and select Prepare -> Extrude -> Retract 5 mm.
If the material doesn’t move back from extruder’s block, you have to move the lever with
the bearing to release the clamp of the filament onto the tracing wheel. Then remove the
filament pulling it next to the Teflon guide nozzle. Remove the reel with the used filament. If
necessary detach the Teflon pipe guiding the filament. To do this, press on a metal ring of
the quick release plate located at the top of the extruder block and pull the pipe up.
STEP 4
Make sure that there is a certain distance (10mm or more) between the working platform of
the device and the printing head. It allows to press the material freely.
If there is no proper distance, enter printer’s menu by pressing OK on the panel. In the
printer’s menu select Jog, then 10mm Movm, and at the end Z MovementMove Z– the
actions are to be confirmed with OK button. The operator panel, for moving the working
table in relation to the working platform, will display. To move the table away from the
head, up arrow must be pressed! At that moment the working table will move away forrom
the head by 10m
STEP 5
Place the reel so the positioning element is in the inside hole of the reel, and filament
unwinds same way as in the picture from 5.4.
Start inserting the filament into the Teflon guiding pipe and continue until you feel
resistance. At that moment filament’s reaches extruder’s block.
STEP 6
In extruder’s block there is a lever with a bearing which presses the filament towards
extruder’s tracing wheel.
Push the lever to insert the filament between the bearer and extruder’s tracing wheel.
STEP 7
Select Prepare from the menu and then Extrude from the list. In the next menu there are
two options to choose and Extrude 5mm should be selected. A single press causes a slight
turn of extruder’s tracing wheel and filament’s movement into the head. Extrude 5mm
should be pressed regularly until there is the even outflow of the material from the nozzle. If
after substantial period of time, there is no plastic thread coming out of the head is not
seen, check whether the filament is properly being inserted into the head – to do so observe
the tracing wheel and the clamping bearing of the extruder. While selecting Extrude 5mm
option, the filament should be in the position between the bearing and the tracing wheel
(see the picture next to); the bearing and the tracing wheel should be turning.
STEP 8
Extrude the filament until new selected filament’s color appears and is regular. If you
changed ABS for PLA, from printer’s menu select Prepare and then Pre Heat PLA. Then
proceed to STEP 9.
If you changed PLA for ABS, leave temperature set unchanged. The process of filament
replacement is finished. The printer is ready to work with the new material.
STEP 9
When the head’s temperature reaches the level set for PLA, select again Prepare -> Extrude
and then select Extrude 5mm. If the pressing process is going smoothly, the process of
filament replacement is finished. The printer is ready to work with the new material.
6. Problem solving
In this chapter common problems, you may approach while using the device, are described.
Connection with a device missing
If after starting YARRH there is no connection with the device, make sure that:
a) when you use USB connection;
the device is connected to power supply and is turned on
USB cable is connected to device’s USB port as well as to computer’s USB port
USB cable is not damaged
If the problem remains unsolved, quit YARRH, disconnect USB cable from the computer, run
YARRH and connect USB cable to the computer.
b) when you use Ethernet:
the device is connected to power supply and is turned on
Ethernet cable is connected to device’s Ethernet port as well as the device enabling
network connections ( router, switch etc.)
the device enabling network connections is connected to power supply and turned
on
there is a connection between the computer and the device enabling network
connections
6.2. Filament’s blockage in the extruder’s block
If during manual intrusion of the filament you notice that there is no outflow of the material
from the nozzle:
Check if motor’s shaft, on which the tracing wheel feeding the material to the head is
installed, is moving.
If it is not, start the device again and then start YARRH.
Check if extruder’s tracing wheel is sliding over the filament. It happens when there
is no movement of the filament towards the head despite the tracing wheel work and
when tracing wheel’s prongs are collecting the material.
STEP 1
Stop the current construction process or the manual material extrusion process.
STEP 2
Remove the filament from filament’s block pressing Retract 5mm. To use the command
enter Main Menu in the panel and select Prepare -> Extrude -> BackRetramm.
If the material doesn’t move back from extruder’s block, you have to move the lever with
the bearing to release the clamp of the filament onto the tracing wheel. Then remove the
filament pulling it next to the Teflon guide nozzle.
STEP 3
After aborting extruder’s work it is necessary to clean the tracing wheel from collected
material to maintain its proper functioning.
Turning the tracing wheel according to the instruction from the previous step, remove the
material from between its prongs till its totally clean.
STEP 4
Remove the filament from the Teflon guide and cut off closing 10 cm to get rid of the part
damaged by the tracing wheel.
STEP 5
If filament’s blockage occurred during printing of the first couple of layers, probably the
printing nozzle is too close to the working platform. If it is, set the position of the head over
the working table again (see 2.3.)
STEP 6
If the platform height is proper, proceed to 5.4. to insert the filament again.
STEP 7
If the nozzle still isn’t passing the material, the most likely reason is the clogging of the head
caused by the ingress of contamination from the outside. It is related to the fact that the no
sufficient cleanliness was maintained in the working chamber. In case of such a malfunction,
call after-sales service.

9. Glossary
Extruder – the element feeding the printing head with modeling material (filament).
Filament – the wire made of polymer (ABS, PLA, or other), most often it is wound on the
reel. It is 3D printer’s cartridge.
Firmware – device’s internal software which operates its basic functions.
GCode – the list of command for a 3D printer and other devices controlled numerically. In
case of 3D printers it is the set of instructions generated on the basis of a 3D model. Using it,
a 3D printer performs all the procedures needed for 3D model construction.
Hotbed – the heated working table of a 3D printer; it is needed for providing a 3D model
with the appropriate adhesion temperature.
Hotend – the heated printing head of a 3D printer it is needed for polymer extrusion.
Kapton – polymer tape, providing appropriate adhesion of 3D models to the working
platform of a 3D printer.
Tracing wheel – extruder’s element with prongs. Thanks to its construction filament’s
pressure on extruder motor shaft causes a change of extruder motor’s rotary movement for
filament’s sliding movement and as a consequence its pressing into the head
Slicer – Software used to generate Gcode list of commands, slicing virtually a model being
printed into layers in which the working material is consecutively put.
STL – 3D models recording format operated by 3D printers’ software.
