Not sure if this is the right forum. I'm trying to generate some pretty basic output from Bobcad-Turn, and what looks like a normal tool path in Bobcad has all sorts of extraneous movements in Mach. Bobcad support calls it "Crop Circles" and they seem to think it has something to do with my Mach setup, since it doesn't show up in their sim. I can repeat the results with a default Mach3 install, though. They suggested I post Bobcad's output here to see if anyone knows what is wrong with it. I attached the output and a pic of what Mach sees when I load it. Thanks in advance - Jeff.

GO TO :
CONFIG>PORTS & PINS>TURN OPTIONS and tick or un tick reversed arcs in front tool post box

That worked, thanks!

There may be a setting in Bobcad or it's post processor but I am not familar with Bobcad.

Charlie,

How do I access and change configuration settings in Tormach Duality lathe version (screen set) of Mach3?

Maybe someone on this site can help if they use that screen but contacting Tormach seems to be a good option to consider.
