Eastwood 60381 Assembly And Operating Instructions Manual page 13

• Thread the Z-Axis Threaded Rod [C] into the brass bushing from the top (FIG
20) of the Z-Axis Stepper Motor Assembly down fully until it is bottomed out in
the collar. Hold the motor flush on bottom and to the upright. Now tighten the M4
screws [CC] that go into the aluminum extrusion, then the pre-installed screws
that go into the motor (FIG 19).
TECH TIP: Look for gaps between the extrusions and the motor, then gently try to spin
the threaded rod back out of the collar. It should be effortless to spin when aligned, but
if binding is occurring, loosen up the motor mounting screws again and utilize thin shims
to achieve perfect alignment. For reference: the pictured unit required an approximately
0.035" thick shim (FIG 21).
• Once aligned, snug the collar so the rod rotates with the motor. The threaded rod
should be completely parallel with the upright throughout the range of motion.
• The 6-Pin Extruder Motor connector tagged E, 6-Pin X-Axis Motor connector
tagged X, and 3-Pin X-Axis limit switch tagged X can all be connected (FIG 22).
• Install the PTFE Tube Fitting [X] to the extruder. Insert the PTFE tube and use the
Tube Fitting Lock Clip [Y] to retain it (FIG 23).
• Install the Filament Holder Upright [K] with the two M5x8 Button Cap Screws
[EE] and M5 T-Nuts [FF]. Install the Filament Spool Rod [M] with the prein-
stalled nut (FIG 24).
