Biqu Frostbite plate for the XL failing bed probing
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?

I have a chest freezer I drop my XL build plate into for a few minutes when a print is a bit too well attached. It seems to help.

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

It only needs to be in the freezer a couple of minutes to chill the thin steel buildplate to a sub-freezing temperature.
Plus, the wife has a Prusa Core One of her own, and an Elegoo Saturn 4 Ultra.

If it's the orange Biqu Frostbite, it is incompatible with 6.4.0 firmware, 6.2.6 is compatible.

RE:
By reducing the nozzle temperature, you can reduce the pulses signal (PWM) that the heater receives. 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.

I've been getting good results with bed probing if I lower the nozzle temperate to 100C during the process.
