/diy/ - Do It Yourself

I bought an anycubic photon during the sale they had and went through a lot of effort trobleshooting and figuring out supports to get some working prints. I use the anycubic eco grey resin.
Noe it is doing this. At the end of the print, it tries to print the entire area of the print bed a few times. I have no idea what is causing this other than some sort of file corruption. I had this issue twice before, but just making a new file was enough to fix it. Now this doesn't work anymore either.
I tried to print some rhino exhaust here, which I had done successfully 2 times before, only my previous two attempts ended up looking like this. Same for another print I tried in between.
I use pruca for orientation and supports, then chitubox for slicing.
Layer height 0.02mm
Bottom layer 3
Exposure time 8.5s
Bottom exposure time 75s
Rest is preset.
I also have a heater installed that keeps the temperature between 25°C to 28°C.
Tried 45mm/min lifting speed once, which is why I originally remade the file I was trying to print, but ended up with only supports and the fep suddenly too loose for printing. So I went back up to 65mm/min, no idea if that failure was coincidence or related.
