The cables for the Z axis go through both sets of cable track. The cables for the Y axis go though only the lower 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 along the base of the router.. Attach the cable track to the brackets on the base and gantry cross bar using M5 screws. See pages 7 and for bracket locations. Upper Cable Track. Install M6 x 5 screw through cable track into motor mount, with hex nut on either side of the cable track.. Secure the flange of the cable track to the closer slot of the gantry extrusion using the M5 roll-in t-nut and flat head screw. Plug the provided emergency stop unit into the port labeled "E-Stop".
