Why Is One Axis Not Moving on My Genmitsu 3018-PROVer V2?
Exact model: Genmitsu 3018-PROVer V2
Safety: Remove cutting tools and disconnect both 24 V and USB before moving connectors or servicing axes.
A.
Start with the accessible checks
What this suggests: If only one axis fails, isolate binding from cable, motor and controller output faults before purchasing a stepper motor.
What to do
- With USB and 24 V disconnected, check the lead screw, coupling, rails and gantry for binding or misalignment; clean debris and realign a skewed nut or guide.
- Inspect the affected axis motor plug and limit leads.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What to do
- Where connector pinouts match the V2 manual, perform the manufacturer's controlled cross-axis motor/cable test only with power removed between changes; a failure that follows the motor/loom points to that item, while failure staying on the original controller channel points upstream.
- Never swap mismatched connectors or tune driver current speculatively.
Confirm the repair
The axis jogs smoothly in both directions without missed steps, crashes or excess motor heat. Internal board repairs remain dependent on the actual controller revision.
