(if this post shows up twice, it's because my computer had a spasm.)

Mach 2 should be posted by the end of next week. I was speaking to Glen at Bobcad support today and he said he will get to it. It will be just about the same as for V21 except when you set spindle direction it will also ask for rpm and a rapid point.
