Homing Sequence Grinding

Has anyone else noticed a change in the A1’s homing sequence? My A1 not initially drives the Z axis all the way to the top where it grinds horribly for a few attempts before driving back down to the bed. I have used my A1 since December with no issues in homing or grinding at all, It has purely started since yesterday for some reason.

Any ideas?

This has only happened to me twice. It was when Bambu Studio “network plugin” was updated.
Second grinding was the hotbed right after another network plugin update.
Power cycling the printer fixed the problem for me.

Lovely, will try this thanks mate, I had a network plugin update in the last couple of days, if all else fails, I might factory reset the machine and start again!
