Version .066 Arc Issue
« on: October 25, 2013, 08:25:47 PM »
So I decided to try .066 and everything seemed fine until I tried running G02/03 commands.  Mach completely ignores both sometimes.  It's always either one or the other.  This issue does not occur in Version .022.

Has anyone else seen this?  In the code below, the G02 is ignored on V.066 and runs fine on V.022.  Did .066 bring about a difference in the way Mach handles G02/03.  The code below is non-modal.  If I change.....

G02 X6.06 Y3.03 I-3.03 J0   

to....

G02 I-3.03 J0

It runs.  Why is that and is there a setting in Mach so that it will run non-modal code.

Thanks

I had the same problem with .066... went back to 0.062 and it works fine.

The problem appears to be only with non-modal code.  Modal commands seem to be fine.  Is there an archive where I can download .062?

062 does the same thing.  I know 022 works, so I started there and found that 024 works and everything later does not.  I can change the post to produce modal arc codes, but shouldn't the Mach be able to process both modal and non-modal code?

Is this possibly a compatibility issue with your motion controller plugin?

Or perhaps your M1101 might have something to do with it?

I know a lot of people are using those versions and I haven't heard of this issue before?

M1101 just turns on the THC and there is not motion controller.  Just PP to a PMDX bob.  It only happens when there is more than one compete circle in a row.  It will cut arcs all day long in either direction and will cut circles in either direction as long as the circles are not back to back.  If you cut a 1" circle followed by another 1" circle it will fail on one or both of the circles.  If you cut a 1" circle followed by something that is not a complete circle then another 1" circle, it all works fine.

If I make the G02/03 code modal it all works fine, which may be why the issue doesn't come up all that often.  Most, if not all, CAM programs post modal code.

What is iside of the M1101 ? It is possible for mach3 to jump over the next Gcode line AFTER a macro is run. Do you end with a While Ismoving()
Wend ??

Just a thought, (;-) TP

M1101 just toggles an output...1 line of code.  I've stripped the code right down to nothing but motion code and it still does it.  I modified the post to produce modal arc codes.  Everything works fine with modal arc codes.
