Trying to use Affinity Designer to do some print and cut tests. Basically, I’ve found the only workflow that works is to both print and upload using the same PDF. If you try to print directly to the printer, everything is slightly larger than it should be, and if you export to SVG and upload that to the Glowforge, everything is also slightly larger (but not by the same amount). I took a look at the SVG, and it is using dimensionless units for the viewBox depending on the DPI you exported at. This thread seems to indicate that GF is expecting 96 dpi, so I tried that, still came out slightly too large.
“Printing” to PDF then using that file to feed both the printer and the Glowforge seems to be the only way to get proper dimensions out of Affinity. Has anyone found any different?
(My quick and dirty print and cut alignment was based off of Jules’ helpful document, but instead of cutting out little windows on the cut sheet, I just cut three registration crosses on a base sheet, then aligned the printed registration crosses on the cut sheet over those by just overlaying it and trying to make out where they were. Turns out it is kind of hard to do that kind of thing precisely using crosses; concentric circle bullseyes may be easier.)
