Two problems I’d like some input one;
Visual alignment expectations. after a job is done and the bed image refreshes the placed art is never exactly over the cut, and as a result the ability to do any back to front or secondarily placed art is impossible (As in cutting a shape, flipping it and aligning another image with the shape by camera only. I understand the suggestion of a jig for this, but should I really expect the alignment to be off by 1/8 to 1/4? Why is there no way to manually calibrate the head?
Scale issues. I am working on a project that requires 2 acrylic parts to be bolted back to back. In the design (Created in Illustrator CC) I created the proper art to engrave (countersink) the holes for the 6 sided nut and the bolt. I measured the nut and bolt with precision calipers and created the corresponding art to the exact dimensions (allowing for kerf and ability to slip inside), and despite working and placing the design at 100%, the holes are no where near the dimensions specified in the design. Its almost as if GFUI has shrunk my design by nearly 10% (I can’t be sure of the % because GFUI doesn’t report the re-scale attributes. Am I missing something? Some setting that would make a cut exactly as I created it? Is there a DPI or LPI setting I need to adjust for Illustrator to avoid an interpolation from design to cut?
