Why Does My Genmitsu 3018-PROVer V2 Fail to Home?
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: A homing failure must be separated by exact GRBL ALARM:6, :7, :8 or :9 or an obstruction: search not found, pull-off failure, or missing switch signal are not the same fault.
What to do
- Inspect V2 limit-switch positions and X/Y/Z-LIM plugs against the V2 board diagram, remove chips blocking switch travel and verify each switch changes its input state when pressed.
- Correct reversed or loose wiring and reposition a misaligned bracket.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What to do
- Manually jog clear of a switch at a safe speed, then retest homing in clear space.
- Change homing direction or travel settings only against the actual V2 baseline and only if mechanically justified; never disable limit protection to hide an alarm.
Confirm the repair
Each axis finds its intended switch, backs off successfully and homing ends without further alarm.
