21 CABLE TRACK INSTALLATION:

Note: It may be easier to route your cables through the track prior to fastening. The cables for the Z axis go through both sets of cable track. The cables for the Y axis go though only the loewr cable track. The X axis does not use an extension cable, this motor plugs directly into the control box.

Lower Cable Track1. Lay out the longer cable track with two pin ends along the base of the router.2. Attach one end to the moving cable track bracket using M5 flat head screws.3. Attach the other end to the fixed cable track bracket on the rear using M5 flat head screws.

Upper Cable Track1. Thread the M6 button head cap screw through the hole in the open end of the cable track then bolt onto the Nema 23 motor mount on the Z axis as shown.2. Secure the pin end of the cable track to the closer slot of the gantry extrusion using the m5 roll in tnut and a M5 flat head screw.

Plug the provided emergency stop unit into the port labeled "E-Stop". This allows the motors to be enabled5
