[BUG] Prusa XL instability.

Firmware version

Printing from...

USB and Wifi / Prusalink

Describe the bug

My XL is unstable with head crashed and filament sensor issues.
The printer has been taken in by Prusa and has been verified to be mechanically and electrically perfect.
Yet the printer remains to fail.
For a detailed log of the case check this forum post:
There are many other report by users and bugs on this repo consistent with my experience:

#4235
#4329
#4304
#4259

While these issues tent to be interpreted as mechanical, in my case the issues persists after Prusa support has completely verified the printer. They are NOT mechanical.

How to reproduce

Normal usage of Prusa XL printer.

Expected behavior

Head should not crash during print or calibration
Layers should not massively shift
Filament detectors should work
Printer should not auto-reset

Hello, please start by updating to 6.2.0-alpha2 firmware.

[SaschaKP]

anyway, this is something I noticed, to remain in topic:

If you end a print and start another one without rebooting the printer, the homing runs slower, after the second print, if you start another print (so this is the third one) this problems became true and the homing takes ages, so I just reboot the printer after every print, and let's hope they fix it, since this is something I see from some time.

this is still true in 6.2.0-alpha2

@SaschaKP slower in what sense? Are some specific moves slower? Or does it do more retries?
