Nozzle crashed into the heatbed

If this occurs it indicates a problem with the P.I.N.D.A. or SuperPINDA sensor. P.I.N.D.A. stands for Prusa INDuction Auto leveling. It is the Z-axis end-stop on the MK2/S and MK3/S. It accurately detects metal within a certain range, so if the nozzle crashes into the bed the P.I.N.D.A. is either adjusted too high in relation to the nozzle, or the sensor itself or its cable may be faulty.

A faulty or maladjusted P.I.N.D.A. can also cause issues during mesh bed-leveling and/or XYZ-calibration.

Testing the P.I.N.D.A. sensor

If the P.I.N.D.A. sensor, or more commonly any of its wires, are damaged there can be multiple different leveling issues. Please see P.I.N.D.A./SuperPINDA Sensor testing for more information.

Lower the PINDA

Lower the P.I.N.D.A. sensor by 1-2 threads, or redo the pre-flight check, where you use the thin tip of the zip-tie instead of the thicker center, which is instructed (circled in red on the picture below).
