Hi, Brian & Steve

Mach isn't reading A axis moves in g-code and MDI line from time to
time, Inc moves seem fine, ABS moves are not.

It's doing it on another computer hear also, Pic's below.

g01 z -.25 f100

Hi Chip

Ignore the toolpath display when an A axis is involved, it often bears no resmblance to what the job is actually going to do. The following is a toolpath display of a file the engraves Test1 around the job, then Test along the job.

Hi, Steve

Yes the DRO aren't moving, When it's acting up it just doesn't load the A axis ABS moves, INC moves are fine, MDI line is sometines intermitent also.

One other thing I've noted is if you make a TAB/MPG move or MDI line move the Screen doesn't update completely, A click on the screen or additional jog move and you can see it.

Just a Bug in there Somewhere, I'd say.

Thanks, Chip
