Ok so I need Peopoly to weigh in here because I am at the end of my ability to debug this issue. The FEP vat simply refused to print larger/taller prints. I am using the same or heavier support numbers as I have before with PDMS and its a fail with broken supports every time. I have tweaked the model orientation, the FEP vat itself, I have leveled and re-leveled repeatedly and each time - FAIL. I have gone back to PDMS but must say I am very disappointed with my $80 vat. It can look as pretty as it wants - if I cant get a print out of it then whats the use? Do I need to print in the middle of the vat? Do I need supports like tree trunks?
