Re: Newbie questions???????

I haven't run into this issue. What version of Mach is it in? I
believe the lasted version I have is 2.6something and there is no
problem other than the m6 bug in the lathe mode. Before that I had
1.something and no problem...

a known bug. What I have found is that if you single step through a
program and then return to continuous mode that something get messed
up in mach3 and then it runs the rest of the program at usually the
rapid traverse speed. I have lost a few cutters using the single block
mode then switching back to continuous. Yesterday running a single
block command then using the run from here feature caused my servo
operated knee to rapidly to some unknown position before I could kit
the estop. The was no Z axis movement called for in the G code file.
I replicated this twice so I would say stay away from the single block
mode. Art and Brian are aware of the first problem and I'll post a bug
report on the yahoo group later today.
