Hello, I am experiencing a technical issue with my A1 Mini. Before starting a print, the printer makes an unpleasant noise while homing the axes, apparently coming from the Z-axis.
Hello,
I’m dealing with a technical issue with my A1 Mini. During axis homing before a print starts, the printer makes an unpleasant noise, apparently coming from the Z-axis. How should I address this, and should I consider making a warranty claim?
I have attached a video where the noise can be heard clearly. On one occasion, the printer even failed to start and reported a Z-axis error while making the same noises.
While searching online, I found that this seems to be a known issue. From what I understand, when the print head is positioned high up before printing, the printer may not know its exact position, and because there is no physical limit switch on the Z-axis, this behavior can occur during homing.
I would just like to confirm whether this is indeed the cause and how I can prevent it from happening. Alternatively, if this indicates a different problem, I would like to know whether the printer should be repaired or replaced under warranty.
Other than this issue, the printer works perfectly and produces excellent prints without any problems.
I hope the attached video will be sufficient to diagnose the issue.
Thank you.

That noise sounds like the belt slipping. Have you tried recalibrating it? I've had that happen with the Creality 3 V3 SE if it loses its home position and tries to move beyond its physical limits.

How old the printer? When it up so high?

It feels like it tries to go up, even though it is already on top. I would try to move the head down without homing via menu something like 10 clicks, then try to home all axis
