Bed leveling failed

Updated 6 months ago ​by Tomáš Chvalina

The Bed leveling failed error appears when there is something wrong with the last stage of the calibration. This calibration is the last step of XYZ calibration and is performed before each print. 

There can be three different error messages related to the Bed leveling failed: 

  • Sensor didnt trigger. Debris on nozzle? Waiting for reset.
  • Sensor triggered too high. Waiting for reset.
  • Sensor disconnected or cable broken. Waiting for reset.

Troubleshooting

Sensor didnt trigger. Debris on nozzle?  Waiting for reset

  1. Make sure the nozzle and heatbed are clear of any plastic.
  2. Do the Z calibration through the LCD Menu - Calibration - Calibrate Z, which also levels the X-axis. 
  3. Try to resume the calibration or start the print again (depending on when the error occurred).
  4. If you are still struggling with these error messages, it is recommended to go through the whole calibration again. You can follow this walkthrough XYZ Calibration & error messages (MK3) or XYZ Calibration & error messages (MK2).

Sensor triggered too high. Waiting for reset.

  1. Make sure the hotend is fully inserted into the extruder. 
  2. Do the Z calibration through the LCD Menu - Calibration - Calibrate Z, which also levels the X-axis.
  3. Try to resume the calibration or start the print again (depending on when the error occurred).
  4. If you are still struggling with these error messages, it is recommended to go through the whole calibration again. You can follow this walkthrough XYZ Calibration & error messages (MK3) or XYZ Calibration & error messages (MK2).

Sensor disconnected or cable broken. Waiting for reset.

  1. Make sure that the P.I.N.D.A. probe is properly plugged into the electronics board. You can double check that using the MK3 EINSY miniRAMBo electronics wiring or  MK2/MK2S miniRAMBo electronics wiring guides.
  2. Visually check the P.I.N.D.A. probe cable, look for any overtightened zip-ties which might be preventing the P.I.N.D.A. probe to work properly.
  3. Check the P.I.N.D.A. probe, you can find more information on how to do that at P.I.N.D.A. Probe testing.
