The Universal Laser Systems unit has arrived. I am still in the process of taking video and stills of the arrival condition and will post shortly in my build log. Remarkably, this thing uses a NEMA 17 motor for the Y, and an even smaller pancake size NEMA17 for the X. You aren't going to believe the pictures! Perhaps this unit wasn't really good at rastering? On the other hand, you won't believe how small and lightweight the x mirror assembly is. It probably only weighs about 4-5 ounces. I will actually weigh it some time and let everyone know.
