As the original poster of Grey v4 always slightly deformed/skewed
I can confirm that the issue was absolutely not resolved with optics cleaning (attempted multiple times).
In fact I have since given up on using the Form 2 because of this, as I haven’t been able to get a useable print from it. I don’t quite have the time or willingness to invest in a whole new resin tank and cartridge to rule those two out as problems, especially as I’m not the only one with these kind of problems I think it might be a futile effort and a (further) waste of money.
