Hey guys,

Just got a brand new Bambu Lab P2S + AMS. It printed the first Benchy perfectly, then I updated firmware to 01.02.00.00… and since then I can’t print anything.

I keep getting:
0300-4015 – nozzle clumping / excessive force error during calibration

Tried everything:
clean nozzle, check movement, reinstall plate, full calibration, restarts
even downgraded firmware (01.01.03.00 and 01.01.01.00)

Nothing works.

Printer is literally new and only did one print.

Anyone ran into this? Is this firmware or hardware?
Would really appreciate any help 🙏
