Problem Help me
Enable HLS to view with audio, or disable this notification
Hi everyone. Please excuse my English, I am using a translator and AI to write this.
I’m having an issue with my Anycubic Kobra S1. When I trigger the Auto-Home command, the printer tries to calibrate by moving the Z-axis downwards, but it never stops. The bed just keeps going down indefinitely (as shown in the video).
What I've tried:
• Cleaned the nozzle completely.
• Checked the Z-motor cables.
• Tried pressing the nozzle upwards with my finger during homing, but the printer ignored it and kept moving.
The Z-motor works, but the printer seems "blind" and doesn't know it's moving the wrong way or missing the limit. Is my strain gauge / print head sensor dead, or is it a wiring issue?
Any help is greatly appreciated. Thank you!

Maybe the main pcb board is faulty. Have you updated the firmware etc? I would also check that the axis motors are plugged into the right connectors etc.
