: If your nozzle crashes into the bed during leveling, you may need to swap the polarity of the black and white Z-signal wires. Filament Runout : Connects to the

Unlike the common V4.2.2 or V4.2.7 boards, the V2.2 has unique pin allocations for the EXP1/EXP2 ports (used for LCD screens), probe ports, and heater cartridges. Misconnecting a BLTouch or a runout sensor can short the board.

On V2.2, you must remove the Z-endstop switch if using a BLTouch. The probe’s sensor signal (PB0) replaces the physical Z-min endstop.

: Creality often uses hot-melt adhesive on connectors; carefully peel or soften this before pulling to avoid damaging the sockets. Voltage Check
