Anycubic error 10118 (X-Axis Homing Failed) occurs on the Kobra 3, Kobra 3 Max, Kobra X, Kobra S1, and Kobra S1 Max when the printer attempts to home the X axis at startup or before a print, but the printhead cannot reach or confirm the home position within the expected time. The error halts the machine to prevent the carriage from grinding against the frame.

What the Error Means

During homing, the printer drives the printhead toward the X-axis end-stop position and waits for a signal confirming it has arrived. On traditional limit-switch machines this means the carriage physically contacts the switch. On strain-gauge models such as the Kobra X and Kobra S1, a force sensor on the printhead detects contact with the frame instead. Error 10118 fires when that confirmation never arrives — pointing to a loose or disconnected X-axis motor cable, a faulty limit or strain-gauge sensor, a physical obstruction on the gantry rail, or a damaged stepper driver on the mainboard.

Step-by-Step Fix

1. From the printer touchscreen go to Move Axis and jog the X axis left and right to confirm the motor responds at all. A completely unresponsive axis points to a wiring or driver fault.
2. Power off the printer. Inspect both ends of the X-axis stepper motor cable — at the motor itself and at the mainboard connector — for loose pins or connectors that have backed out of their housings. Reseat firmly.
3. With the printer powered off, slide the printhead manually along the full length of the X rail and feel for any binding, grit, or obstruction. Clear any debris and confirm the carriage moves smoothly end to end.
4. On strain-gauge models (Kobra X and Kobra S1/S1 Max): remove the printhead cover and inspect the strain-gauge assembly for visible damage, debris caught against the sensor contact surface, or loose ribbon cable connections. Clean any filament residue from the hotbed surface that could trigger a premature force reading.
5. Re-run the homing sequence from the touchscreen. If the axis now homes correctly, monitor the first few prints to confirm stability.
6. If the motor remains unresponsive after reseating cables, test with a spare stepper motor if available, or contact Anycubic support — the X-axis stepper motor or the mainboard stepper driver may require replacement.

Parts Required

• Replacement X-axis stepper motor (if motor is confirmed faulty)
• Strain-gauge / leveling sensor assembly (Kobra X / S1 models, if sensor is damaged)
• Multimeter (for continuity checks on motor cable)

If error 10118 persists after all cable and rail checks, contact Anycubic support for mainboard evaluation.
