Anycubic error 10119 (Y-Axis Homing Failed) appears on the Kobra 3, Kobra 3 Max, Kobra X, and Kobra S1 when the heated bed cannot reach the Y-axis home position during the startup homing sequence. The printer stops immediately to protect the frame and motion system from a crash.

What the Error Means

The Y axis drives the heated bed front-to-back. During homing the bed travels toward the home end-stop, and the firmware expects a signal confirming it has arrived. On the Kobra 3 Max, two Y-axis motors work in tandem to move the larger bed — a loose connector on either motor can prevent homing. On strain-gauge models like the Kobra S1, force detection replaces a physical end-stop switch, so debris under the bed or a faulty sensor are additional failure points. Error 10119 indicates the confirmation signal was never received within the allowed time.

Step-by-Step Fix

1. Go to Move Axis on the touchscreen and jog the Y axis forward and backward to check that the bed responds to commands. If the bed does not move at all, the motor circuit is the primary suspect.
2. Power off the printer. Inspect the Y-axis motor cable connector at the motor and at the mainboard. On Kobra 3 Max — which uses dual Y motors — check both motor connectors and reseat any that feel loose or partially inserted.
3. Crouch down and look under the heated bed for any object, fallen screw, or filament wad that could prevent the bed from traveling its full stroke. Remove any obstruction.
4. On strain-gauge models (Kobra S1): remove the printhead and clean the underside of the hotbed with a dry cloth to remove filament residue or dust that could cause a false force reading during homing.
5. Re-run homing from the touchscreen and observe whether the bed moves freely all the way to the home position.
6. If the bed still fails to home after clearing obstructions and reseating cables, the Y-axis stepper motor or the mainboard Y-axis driver may have failed. Replace the motor or contact Anycubic support for mainboard evaluation.

Parts Required

• Replacement Y-axis stepper motor (if motor is confirmed failed)
• On dual-motor models: spare Y-axis motor set (Kobra 3 Max)

If error 10119 recurs despite clear rails and secure cable connections, contact Anycubic support for further diagnosis.
