Automatic Bed Probe Did Not Trigger During Leveling
Quick Answer
Error code PROBING_FAILED on your Creality FDM 3D Printers means: Automatic Bed Probe Did Not Trigger During Leveling. This is usually fixable — see the step-by-step guide below.
Likely Causes
  1. CR-Touch or BLTouch probe pin is bent or stuck
  2. Probe wiring disconnected or has a broken conductor
  3. Probe mounted too high and cannot reach the bed surface
  4. Electromagnetic interference causing false or missed probe triggers
  5. Probe deploy/stow mechanism jammed
How to Fix It
1
Inspect the probe pin for bending or debris and gently straighten if needed
2
Verify the probe deploys and retracts properly by sending M280 P0 S10 (deploy) and M280 P0 S90 (stow)
3
Check the probe mounting height and adjust so the pin touches the bed before the nozzle
4
Inspect the 5-pin probe cable for continuity on all wires
5
Try running the probe self-test: M280 P0 S120
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
