Known Issues

warning

PINDA probe drift

The PINDA probe can drift with changes in temperature, affecting print bed leveling.

Mitigation: Use Mesh Bed Leveling compensation and perform Live Adjust Z calibration.

info

Filament sensor sensitivity

The filament sensor can sometimes be overly sensitive and pause the print unnecessarily.

Mitigation: Disable the filament sensor in the settings if false positives become an issue.
