How do I fix cr touch / bltouch leveling failure?
- 1
Check the probe pin moves freely — gently push it up with your finger. If it sticks, the internal magnet or spring may be worn. Replace the probe.
- 2
Verify wiring: the 5-pin cable should be firmly seated at both the probe and mainboard. A loose connection causes intermittent trigger failures.
- 3
Recalibrate Z-offset after every probe replacement or bed surface change. Home Z, then paper-test at the center and adjust offset until slight drag.
Pro tip: Proper bed leveling is the foundation of print quality. Ensure probe and Z-offset are calibrated before adjusting any other settings.
