The PWM pulses affect the loadcell, as described in this bug:

https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/5261

Check if disabling the heating works. Using this workaround, I need to compensate for nozzle thermal expansion in Slicer (+0.06mm), because after bed leveling is done with cold nozzle, the nozzle will expand (grow) when heating, so the first layer will not be ok. So the tool needs to be raised 0.06mm to compensate for the longer nozzle.

So I picked up the Biqu Frostbite plate for testing (mostly in the hopes that Biqu will see the potential demand and release the Glacier plate for the XL) and I have only had one print 'work'. Multiple PLA prints would just never get past bed leveling. The one print that I had that completed seemed OK but the bond was so strong that the the print would not release. I'm guessing that leaving the default temps resulted in the super bond...

The test print seemed to complete OK, once past the bed probing issues. I let the print cool down and could NOT get it to lift. I reheated the bed and you can see the results. 

Anyway, anyone have any success yet?

Plus, the wife has a Prusa Core One of her own, and an Elegoo Saturn 4 Ultra.

The wife will be happy about randomly finding a print plate in the freezer...
