Auto-Leveling Probe Failed During Bed Mesh Calibration
Quick Answer
Error code PROBE_FAIL on your Anycubic FDM 3D Printers means: Auto-Leveling Probe Failed During Bed Mesh Calibration. This is usually fixable — see the step-by-step guide below.
Likely Causes
  1. LeviQ probe is dirty or has debris on the sensing surface
  2. Probe is mounted at incorrect height relative to the nozzle
  3. Bed surface material not compatible with the inductive probe (non-metallic beds)
  4. Electrical noise from the heated bed interfering with probe readings
How to Fix It
1
Clean the probe sensor face with a dry cloth to remove any filament or dust
2
Verify probe mounting height: the probe should trigger before the nozzle contacts the bed
3
Run the auto-leveling procedure with the heated bed at room temperature to eliminate thermal interference
4
Check the probe cable for continuity and secure connections at both ends
5
If using Klipper firmware, verify the probe configuration in printer.cfg (pin, speed, samples)
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
