Can anyone tell me why this gcode is causing the circles around the toolpath origin? I have attached a photo of the mach3 screen, a photo highlighting one of the offending lines, another photo with another offending line. It seems to be every other g2 line. Attached id the xml file for this machine, I am on windows 7 Plenty of cpu power. If I take out the holes with the g2 code it runs fine. I don't know what the problem could be. The problem starts at the drill 13 section. I am using a 3/16 (4.8) bit to make a 1/4" (6.3) hole.

In Config / General Config change your IJ Mode to Inc that will get rid of the crop circles. ;)
In this instance, In your GCode define that the arcs have been created in Incremental Mode (as opposed to Absolute Mode) with G91.1 at the start of the code.

I was thinking crop circles but I didn't want to say it. Don't want people to think I'm whacky.
Thank you very much that took care of my problem.

No worries Frank, everybody knows that I am whacky. ;D
Pleased that you got it sorted.

Just wacky enough to keep all of our machines running correctly.
