I have a print offset problem with my old Form 1: the black piece of preform is printed where the white piece is.
how to adjust this shift?
The offset is 15mm !!

I think there’s a setting in Preform to adjust X/Y offset for the Form1. Many years ago, after I took my Form1+ apart to clean the optics, the prints were offset about 5mm to the right. If I printed at the far right of the build platform, the model was actually 5mm offset past the edge of the build platform. There was an adjustment I was able to make to correct it But it’s been many years, my Form1 is no longer in use, I can’t recall the details.

No idea. Put something small in the center of the build plate and then change the offset to 15mm and print. If the part isn’t in the center, change the offset to -15 and try again.
