11.) Grease the end of the trapezoidal screw, insert the tracking trapezoidal screw into the flange,
and assemble the unit on the adjustable baseplate using three M6 x 10 mm screws. Loosely
tighten these screws.
12.) Measure the distance between the tracking trapezoidal screw and the linear bearing at both
ends, and correct the positioning until the distances are equal and the tracking trapezoidal
screw is parallel to the linear bearing. (This prevents the screw from seizing up.)
13.) Tighten the three M6 x 10mm screws.
14.) Connect the nut holder to the gantry back beam using four M6 x 16 mm screws.
15.) Drive the gantry back and forth on its rails to ensure that the drive mechanism is functioning
properly.
