Hey guys and gals, I need help calibrating my projector from scratch. It's been tinkered with a little bit but I'm not too happy with the print results. My square measurements don't seem to make any sense and the front of the projection grid is never as crisp as the back. So, if I were to calibrate it completely from scratch, how should I begin? I'm hoping to use as little resin as possible. Thank you all in advance!
