Failing quality without changing anything

[MargoArgo]

If your film sticks to the quartz, it's not clean. Keep wiping with alcohol and soft cloth. Make sure the lens on projector and the front glass on printer is the same way. Double check your computer settings. Did you have a Windows update? It can change your settings.

So I got the cleaning kit and cleaned everything. I still see lots of dust there and looks like it's inside the printer, will have to try cleaning there too, because the prints still fail.
But with all of that said, prints consistently fail on one side of the platform. What else can it be if not dust? I switched internet off and there was no update. The film is getting more worn, it is sagging more than in the beginning, can it be the cause? that the film simply doesn't connect really tight with the quarts?
(we really should make a cataloque of typical mistakes with example pictures here on the forum..)

Have you checked and adjusted your build table?

After adjusting make sure to do the "on all 4 the corners paper test" to insure that the build table is flat to the quartz.

I've adjusted the table, initial layers of the print have no problems sticking to it, it's what comes next mostly remain on the film. And what is this test?

I've changed the film, last one was already worn, but no improvement to the tesilts. What is film adapter? I'm learning new words here..

Who did you purchase your machine from? I suggest contacting the reseller for a more hands-on diagnostics of your printer.

Please watch this short video which explains how to use the film adapter to change your film. The acrylic/plastic adapter is 1mm thick, you can use something else if you don't have an adapter. It is important to have a 1mm space between the printer and the base of the resin tray to ensure correct tension of the film - otherwise it will be too loose/tight.

Well, I got it from Micron3D, and I'd love to get some official help from them, but the whole support team is on vacation in August, so here I am.
