This isn’t really a high priority issue, but it is important.
Back in the early days, there was talk that the Glowforge web app would be able to read Photoshop and Illustrator files natively. That was a pretty compelling feature for us, as the lasers we’d used (Epilog, Trotec, ULS) all could read the same types of files… it seemed like a fairly common feature. Simply set the line to a certain width (such as .001") for cutting, and everything else would be treated as an engrave.
Please add similar support to Glowforge, that would make it easier for us to print our designs in the popular design software’s native format, instead of having to play around with exporting files in intermediary file formats.
