new VAT that do not work
Hello,
i bought two vats in august, brand new.
i have been using one during 3 months non stop, and everything was fine with it. It is the kind of vat all transparent.

obviously, the vat got sticky and i could not print anymore. So i took my second vat all brand new and i got exactly the same problem, i can not print nothing with the brand new vat, everything stick to it and i can not make one good print.
i do not understand how the new vat can works so bad, can the fep get damaged by the time (the vat was packed in plastic since i bought it.
thanks for your help.

I have had a very similar problem to you, where nothing I do will get the prints to stick to the platform. I realized later that wear and tear of the platform from sanding and removing prints produced micro irregularities which are difficult to spot with the naked eye. These irregularities cause the platform to be imperfectly flushed with the resin vat, causing prints to remain on the vat.
My solution was this: once the platform is lowered into the vat and after it has been pushed downward three times, carefully and gently push down the platform slightly. You will see that there's an allowance of a millimeter or even more before the springs compress. While doing this, fasten the vertical locking knob immediately and try a print.
Hope this helps!
