Why Won’t the Spindle Spin 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 the spindle runs when commanded manually but not during a file, the problem may be missing M3/spindle-speed commands.
What to do
- Remove the cutting tool, isolate 24 V/USB before handling spindle cables, then check the Spindle connector polarity and cable fit against the V2 wiring diagram.
- With the area clear, use Candle's supported manual spindle control at a safe setting.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What this suggests: If it never runs, inspect the spindle connection and drive path.
What to do
- If manual control works, check whether the job includes a correct spindle-start command and speed, with a stop at its end.
- If manual control fails, use the maker's controlled output/motor isolation checks for the fitted board; replace the diagnosed cable, spindle motor or controller part, not all three indiscriminately.
Confirm the repair
The unloaded spindle starts and stops on command and operates throughout a test toolpath without loose electrical contacts.
