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..)
