MOTOR VARIATIONS
While the NEMA 14 motor is what is
called for in the BOM, we also support
NEMA 17 motors for those who are
sourcing their own parts. NEMA 17
motors tend to have more torque but
need to run at lower speeds. Use what
works for you!
SET SCREWS
Insert both M3 set screws and use
thread locker on them.
Use the appropriate pulley tool to
install the pulley at the correct height
on the motor shaft.

GEARBOX
PULLEY HEIGHT
Use the Pulley_Tool_NEMA14 † to
set the correct height of the GT2
20T gear.
If you are using a NEMA 17 motor
for the gear axis, assembly is the
same but you’ll need to use
Pulley_Tool_NEMA17 † and print a
different Motor Arm to mount it.
