Snapmaker U1

How to reproduce

Printer set to "support multiple beds." Select Textured PEI plate under my PLA filamement. Ensure temperature is 60C for textured plate. Print file. The heatbed appears to turn off sometime after the print started and the object comes off the bed. I tried starting the heatbed manually before the print, but it still turned off. I set the bed temp after the print started - that seemed to stick around.

As background: I'm using the Paxx U1 extended version of firmware.
The filament in slot 1 (PETG) and two PLA prints from the current slot worked fine since the Firmware change. I was trying to save a Printer preset when Orca crashed on me earlier today (12/3/2025)and since then I'm having this trouble.

Actual results

Heatbed turns off early in the print.

Expected results

Heatbed to keep temperature
