Hello, I got an issue, which seems to get worse over the time: the printed parts don't stuck to the front of the bed. I have postet this in the German Anycubic Photon forum some time ago, but all I was told to do didn't solve the problem.
My first prints where perfect, I used 4 BL with 22 sec. BE time. Then more and more often the first parts didn't stick, so I got higher with the values to 25 and now 40 sec. BE time. The parts getting an elephant foot, but as you can see, only about the last 4 rows (of 9) has stuck to the bed.
What I've done so far: leveling, leveling the Rich way (with tray), leveling again (and again, and again...), today I changed the FEP film (very carefully), disassembled the head of the bed for a cleaning, tightened everything up thoroughly, also used RainEx for the FEP, of course leveling again... and the first picture is the result.
Is it possible, that the UV-LEDs are already done? I printed about 5 hours with them! (see third picture)
Please help, I'm completely clueless at the moment, and I think I've done everything, what has been told me.
(EDIT: last picture with all settings and what it should look like)
