Re: [CAD_CAM_EDM_DRO] Re: Newbie questions???????

I was running the latest version 3.0 of a few days ago but have noted this way back into early 2.0+ versions. It still there. Art acknowleges it.
I have replicated it several times as noted by some broken cutters.

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...

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.
