Just a simple question about my Fep sheet getting dented after print.
I just bought an Elegoo mars 2 Pro and had trouble getting it to stick to the bed, after some painful bed leveling and realising my exposure times were too low for maroon resin, I finally got it to stick to the bed by the 4th print.
Now before I start my next print I want to know what causes the indents in the fep sheet below, so I can prevent it from happening again. [![enter image description here][1]][1]Is it too High exposure time, bed leveled too low/tight, or both?
Now I will also note, that this print was with the standard rook test print the mars reccomends you do first, also that my print was very hard to remove from the bed when finished, I had to use alot of force to rip it off.
Thank you appreciate the advice.
