Hello!
First, sorry my english. It,s bad, like my latest prints.
In pic you see my problem.
I’m tried to fine tuning, sanding and resin filtering. Nothing helps.
First litre was fine, but now there is too much problem. I don’t know is the problem latest preform updates or latest resin update but that’s when problem starts.
If mirrors and galvos are clean and the tank is clear not cloudy, you may need to open a support ticket with Formlabs.
Looks like just a failed print but hard to tell what is wrong because we don’t know what the part is supposed to look like. Do you have a screen shot of the part in PreForm for people to see?
