Anycubic error 10237 (Auto Leveling Error) occurs on the Kobra 3, Kobra 3 Max, Kobra X, Kobra S1, and Kobra S1 Max when the automatic bed leveling sequence cannot complete successfully. The printer cannot reliably measure the distance between the nozzle and the build surface, so it stops rather than risk a first layer that is too close or too far from the bed.

What the Error Means

These Kobra models use a strain-gauge leveling system built into the printhead: the nozzle physically touches the bed at multiple probe points, and the force sensor detects contact. Error 10237 fires when the probing sequence produces readings that fall outside the acceptable range — meaning the sensor did not detect contact, detected it at the wrong height, or recorded inconsistent values across probe points. Common causes include filament residue or adhesive debris on the build plate surface interfering with nozzle contact, a damaged or loose strain-gauge assembly on the printhead, a warped or improperly seated build plate, or a disconnected leveling sensor cable.

Step-by-Step Fix

1. Remove the build plate from the bed and clean it thoroughly with isopropyl alcohol (IPA) on a lint-free cloth. Remove all adhesive residue, glue stick, hairspray, and any raised filament blobs — any surface irregularity can prevent the nozzle from making clean contact with the plate.
2. Inspect the strain-gauge assembly on the printhead for visible cracks, deformation, or loose screws. The sensor is mounted behind or above the hotend; it should be rigid with no play.
3. Check the leveling sensor cable at both the printhead end and the mainboard end. Unplug and firmly reseat the connector. Inspect the cable for any kinks or damage caused by cable-chain flexing.
4. Reseat the build plate on the magnetic bed surface and confirm it lies flat without any lifting at the corners. A warped plate will produce inconsistent probe readings.
5. Navigate to the leveling menu on the touchscreen and re-run the auto-leveling routine. Monitor the printhead as it probes — it should tap the surface gently and lift cleanly at each probe point.
6. If the error returns, manually move the printhead to several positions above the bed and confirm the nozzle height looks consistent — a badly warped bed may need shimming or replacement.
7. If the strain-gauge assembly is physically damaged or continues to produce bad readings after cleaning and cable checks, replace the strain-gauge / leveling sensor assembly.

Parts Required

• Isopropyl alcohol (90% or higher) and lint-free cloths
• Replacement strain-gauge / leveling sensor assembly (if sensor is damaged)
• Replacement build plate (if plate is severely warped)

If error 10237 persists after cleaning the bed surface and reseating all sensor connections, contact Anycubic support for further assistance.
