So if we have determined that the bug occurs on the xilifeng, csmio, smooth steppers, and the galil controllers I think its safe to say that it is a Mach3 issue. Is this on the radar to be patched in the next release or is there someone that we should email to make sure that it gets the attention that it needs?
It's a very dangerous problem that could get any one with a motion controller board in conjunction with mach3 hurt. When I was first learning to use my machine I had an aluminum plate turn into a flying buzz saw that took out a nice piece of wood from a nearby chair and some of my wall as well because I accidentally plunged a 45 degree face mill into it. It was my mistake that time, not mach3's, but with a bug like this it could happen to anyone.
