Firmware - Prusa Firmware

I´ve updated the P3P to Firmware: and I updatet the MK3s to and run into an issue I didn´t see before.

It looks like the print head didn´t move up and stucked or crashed into the purge tower. The magnetic printplate was moved (picture). And the printer purged a fat line of PLA over the print plate.

Is there still a problem with the P3P and MKS - Should i downgrade to

Includes the canvas sliced File:

BigOwl Body Claws SmallOwl Beak

I steped back to v3.9.xx with the MK3. Now it doesn´t start printing alone. Filament is loaded - the Printhead goes to 0:0 and then everything stops.

The first time i didn´t recognise the MK3 display. I thought it stopped and the print “died”. So I cleaned the p3p and the prusa and restart it. Same result -> then I saw on the screen “Waiting for User”
