Print Settings

1Z axis settingsBefore commencing the printing process you need to adjust the screw that regulates the height of the Z axis, so that the extruder is positioned at the correct distance from the bed. To do so, follow the steps below:

1 Balance the ends of the X axis, using the screw to manually adjust each axis until they are both at the same height.

2 Tighten the adjustment screw until it extends 4 mm above the printed part.

3 Move the extruder to its starting position by selecting the Control > Move axis > Auto home options on the LCD control panel.

Note: manually check that all the endstops touch their respective axes.

4 If it has not yet been adjusted, make sure the endstop-adjustment screw is in the correct position and move the extruder to its starting position.

2Levelling the print bed

Once you have adjusted the Z axis you need to level the bed, so that it is totally parallel to the X axis:

1 Start the levelling process by selecting the Control > Level plate options on the LCD control panel.

3Printing your first object

If you have followed all the steps in the manual, your Prusa i3 Hephestos will now be ready to print its first object!

First, you need to divide the 3D design (the .stl file) of the object you want to print into layers. To do so, follow the instructions in the manuals we have prepared for some of the most popular 3D design programs:

Slic3r Manual Repetier-Host Manual Cura Manual

Once you have obtained the .gcode file for your object, save it onto an SD card and insert the card into the slot at the back of your printer’s LCD control panel. Then go to the main menu and select the SD Menu option. This menu will display the names of the different objects that are available to print: select the name of the file you saved. Once you have selected it, the printer will automatically start working.

You can monitor the progress of the printing process and the extrusion temperature on the printer’s LCD screen. When the printing process is complete, release the clips and remove the glass base. Rest it on a table and remove the printed object by pulling firmly.

Note: when configuring the slicing software, bear in mind that the Prusa i3 Hephestos print area dimensions are 215 x 210 x 180 mm.

Important

To make sure the object adheres to the base correctly, you will need to apply a fine layer of lacquer to the base or add masking tape.
