I’m sorry you ran into trouble when trying to start this print. I’m glad to hear that rasterizing the text got you up and printing with this design. Regarding highlighting open paths, we haven’t announced anything like that yet, but I’ll pass your suggestion along to our team with a note that it came from a customer request.
Also, I’d be happy to take a closer look at the file you were having trouble with. Would you please share a copy of the file which resulted in the message about the design containing filled open shapes? If you’d prefer to share it privately, you can email it to support@glowforge.com. Thank you!
