I have a brand new problem with my Artsign JSM40 (very similar to the Rabbit and all the other Chinese lasers).
The machine has been working fine for a while now, though I haven't used it much. When I use the "Laser Test" buttons, the laser fires just fine. Revently, however, when I try to engrave using NewlyDraw, the carriages move, but the laser never fires.
I've tried power cycling both the laser cutter and the computer, as well as re-installing NewlyDraw, and reseating the parallel cable on both ends. None of these solutions helped.
Has anyone ever seen this problem before? Any ideas on what might be wrong?
