Hello,

I have issues with my Form 2, when my print volume is wide in the X & Y direction (Horisontal surface). Printing Walls 3-4mm, vertical it seems to go much better, but the surface of the print isn’t to good as well, seems a bit “crumbled” like there is microcured Resin stuck to the surface.

Can anybody help diognosing my Form 2 printer.

Thanks in advance,  
Kind Regards Frederik Voldbirk

This is most likely a broken centroid, so the printer can’t correctly calibrate the movement of the galvos. This is a failure mode we’ve seen before on form 2s, especially now that they’re getting old: the galvos are wearing out, which causes the part to stretch out more and more in those axis. You _could_ distort the part before uploading it into PreForm to account for the galvo drift, but there’s no guarantee that it won’t do something different next print.
