From the top of the X Plate Extrusion, thread the
178mm lead screw through the anti-backlash nut
connected to the Z Plate. Continue until the lead
screw is sitting in the pocket on the UHMW Screw
seat.
Place the coupler on the top of the lead screw. Leave
loose.
Grab the Z Motor Mount. Place the shaft of the
motor into the top of the coupler. Leave loose.
Lubricate (2) #10x1 self-tapping screws. Place them
through the Z motor mount into the holes at the end
of the X Plate Extrusion. Tighten with the 8mm
wrench.
Using the 2.5mm Hex Key, tighten the coupler to
the motor shaft and the lead screw.
The lead
screw MUST be firmly against the UHMW piece
at the bottom of the assembly or the coupler
will separate, causing the Z axis to lose height
during operation. Make sure the coupler does
not separate when the Z axis plate is pulled
downward.
