I’ve reported this in the past & have been exchanging emails with GF Support, but they have not resolved the issue yet.
I keep getting a “Print Load Error” with the following text. "We’re sorry, an error occurred while preparing this print. "
I’ve tried restarting my computer, using both Edge & Chrome browsers, restarting the Glowforge (GF), and using the Glowforge Founder Ruler as the file to print rather than my simple circle inside a square cutout that I created with Inkscape.
I’m using proofgrade material, which the GF correctly identifies.
This seems to happen randomly. With absolutely no changes on my side (as opposed to the GF processing side) it will eventually start working.
