Bambulab H2D - Sunlu Petg

Standard Bambulab Petg Settings

Bambu slicer

I regularly have the problem that I can't get the bottom layer off the Bed. The prints sometimes fail, but for different reasons. I have already damaged the bed jn multiple places from scraping roo aggressively.

The Printer is in my workshop office, and I have never cleaned the bedplate. I often remove prints with dirty / greasy hands.

Any advice ?
