3D Printing Forum

I have a Longer Orange 30 Printer. It was working fine for a few weeks. But now when I make a print the whole vat of resin gets filmy. I have all the necessary tool, equipment so the ambient light isn’t a problem.
When I checked the LCD screen I noticed some black spotting. One big one and multiple small ones.

Hi, welcome to the forum.

I'm guessing the LCD screen is completely clean. If this is so it could need replacing.
Have you had the printer long?
Do the prints come out OK?
Do you make sure the resin is well mixed before putting into the vat. You need to give it a good shake to make sure. If not the resin can settle.
