Printer

Bambulab P1S

How to reproduce

When starting a print with the AMS enabled, the printer only heats to the material it is going to print with ie PLA 220C --> this means that the machine is not able to load the filament correctly. The workaround is that I have to manually load the filament via the Bambu handy app

Actual results

"filament feed error"

Expected results

the AMS should be heating up to 250°C to change material
