Automatic bed leveling not working?
RE: Automatic bed leveling not working?
What happened before this, you give no info?
What did you do to resolve this?
If you move the printer or had a crash, do a z-calibration, with a heated bed and nozzle.
Clean nozzle? Extruder to loose, check the whole printer on loose bolts, screws etc.
7x7 mesh leveling, this is a setting in the printer,is better then the 3x3.
Steel sheet not good on the bed.
