Parts:
-
z_motor_mount_a×2 · bin 02-Z0, 02-Z2 -
z_motor_mount_b×2 · bin 02-Z1, 02-Z3 - M3×8 SHCS ×12 · Fasteners, Tools & Misc box
- the four Z motors with their 16T pulleys · already on the bench
Do:
- Set the motor's round boss in the plate's half-round notch, cable exit oriented as in the graphic.
- Fit three M3×8 SHCS through the plate's counterbored holes into the motor.
- Build all four: two
amounts, twob.
Check
All four cable exits point the same way relative to their mount, the 16T clears the mount, the foot's two M5 clearance holes unobstructed.
What you're looking at
Manual p.39: the motor bolted to z_motor_mount, the L-bracket that stands the motor off the frame. The mounts are mirrored _a / _b, and the two hands put the motor's cable exit on opposite sides. Three screw holes only: the fourth corner is open by design.
Caution
Rev D+ / LDO: the manual's own stepper wiring instructions do not apply to this kit. Wire the Z steppers per the LDO Rev D wiring guide (Z0 front-left→STEPPER-0, Z1 rear-left→STEPPER-1, Z2 rear-right→STEPPER-2, Z3 front-right→STEPPER-3). Label each motor cable now: in Chapter 10 the four are indistinguishable. src · wiring guide
Tip
Stood on its print face, thick foot arm on your right running toward you: the thin motor plate is the far edge on _a, the near edge on _b.
Good stopping point · ~25 min since the last one
four Z motors carry their 16T pulleys at 10.7 mm and are bolted to their a/b mounts with the cable exits matched. Get every remaining 16T pulley off the bench before you walk away, and leave the motor cables labelled.
