I have just purchased a Phrozen Shuffle XL. Printing has been printing really well, however I have had some issues, not with the print itself but from very thin cured resin sticking to the FEP, but not in the area where the print is actually happening. There is very thin cured resin outside of where the print is even happening, it has no affect on the print itself but it is annoying having to clean it out after every print, when I am just trying to print right away again. Can anyone help me out as to what could be causing this? How to fix it? Thanks.
