This is I was unclear. They don't say which program. Probably the best result of two. And some software just breaks arcs to lines anyways.

It defaults to 180: 180mm, 180in? That's ridiculous. That is why I can't say which actual tolerance Mach3 has. And they can't explain it either. The "winner" is KMotionCNC. Hard to say how exactly they tested... but it breaks arcs to lines by default. Seems to have more intelligent settings http://www.dynomotion.com/Help/KMotionCNC/TrajectoryPlanner.htm But judging by their own graphs it violates acceleration limits repeatedly and severely. I tried to set the same parameters to LinuxCNC and it showed 3:05. Without any violations! Wow, that surface finish is quite ugly when using those Mach3 settings.

At least for lines (arcs processing is not perfect, e.g. run arcs.ngc and check how it slows down a few times on the large ellipse) Interesting to compare the new TP to industrial CNCs.

It never shows non-zero when paused, only when stopped completely, exactly with the empty queue. I'll check when it gets to 2.7 Thanks again for the bug report!
