Form2 stopped printing, now all I get is "failed" for each new print, WTF!

Anyone have a suggestion for this one? Just finished a print and now every print I load starts up, plate goes into resin, and then I get a “Failed” message. Reset it, still no work, and now giving occasional “cartridge missing” error. These machines are such bullshit! Can’t wait for the semester to end so I can get a new Method X and start scrapping these POS machines!
