on a whim picked up a vacuum table for sale on CL. guy had been using it for small run prints for the longest, I brought it home and possibly moved something so now the vacuum platen does not sit flush.
Tried looking for info online and seems its mostly used for printing circuit boards, and most have an acrylic top (mine is aluminum top, looks pretty home brewed).
does anyone have ANY experience with these???
