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 Track. Lay out the longer cable track with two pin ends along the base of the router.. Attach one end to the moving cable track bracket using M flat head screws.. Attach the other end to the fixed cable track bracket on the rear using M flat head screws. Upper Cable Track. Thread the M6 button head cap screw through the hole in the open end of the cable track then bolt onto the Nema motor mount on the Z axis as shown.. Secure the pin end of the cable track to the closer slot of the gantry extrusion using the m roll in tnut and a M flat head screw.
