Anycubic error 10107 (Filament Broken / Abnormality) appears on the Kobra 2, Kobra 2 Pro, Kobra 2 Plus, Kobra 2 Max, Kobra 3, Kobra 3 Max, Kobra X, Kobra S1, and Kobra S1 Max. The printer has detected that no filament is present, either because the spool has run out, the filament snapped mid-print, or — in multi-color setups — the ACE Pro material box is not properly connected.

What the Error Means

The filament runout sensor (also called the material-break detection switch) monitors the filament path between the spool and the extruder. When the sensor detects the filament has been interrupted — whether by a genuine runout, a snap in the strand, or a false trigger — it immediately pauses the print and raises error 10107. On printers equipped with the ACE Pro color engine (Kobra 3 series), this code also fires if the ACE Pro signal cable is loose or unplugged, because the system treats a disconnected material unit the same as a missing filament.

Step-by-Step Fix

1. If you are using an ACE Pro / multi-color setup, check that the ACE Pro signal cable is firmly seated at both the unit and the printer’s board connection port. Unplug and reseat the cable to clear any intermittent contact.
2. Open the filament path and visually confirm that filament is present all the way from the spool to the extruder inlet. Look for any point where the strand has snapped or kinked.
3. If the filament has genuinely run out, load a fresh spool: cut the end cleanly at a 45-degree angle, feed it into the PTFE tube, and use the printer’s Load Filament menu option to advance it to the nozzle. Then resume the print.
4. If filament is present but the error persists, manually push a short length of filament through the runout sensor and confirm the nozzle extrudes normally — this rules out a sensor false-positive.
5. With power off, inspect the runout sensor body and its cable connector for debris or damage. Blow it out with compressed air if needed.
6. If the sensor continues to trigger with filament correctly loaded, the sensor switch may be worn or stuck. Clean or replace the filament runout sensor assembly.

Parts Required

• Replacement filament runout sensor (if sensor is faulty)
• PTFE tube cutter or scissors (for trimming filament end at 45 degrees)
• Compressed air (for clearing sensor debris)

If error 10107 persists after loading fresh filament and reseating all cables, contact Anycubic support for further diagnosis.
