Lithophane print lifting off Bed
I have been having difficulties printing flat lithophanes on my Prusa Mini with PLA material. Print lifts off bed in the middle of printing as shown in the above picture. PLA filament print with 10mm brim, zero offset of brim from the print. Nozzle Temp 220C; Bed 60C. First layer prints perfect with a Z offset of -0.650.
The same lithophane sticks on Bed, well with PETG at 240C and Bed 85C. However there is some stringing with PETG.
All advice and recommendations are welcome.
I'm not sure if elefatns foot compensation could be interfering with the brim. Try setting it to 0 as well.
Other then that i could only try to thurougly wash the buildplate and try again.
Lay the print down flat. Problem solved
