unwanted circles along curve

[Pbrew1]

In my drawing I have a curve, when I simulate the g code I get small unwanted circles along the curve. Im new to this , any suggestions?

Thanks,
Paul

What software are you using? I had a similar problem using g-code generated using a Mach 3 demo and trying the same code in EMC (AXIS). One used I-J absolute and one used I-J relative (I don't remember which was which)

I am using bobcad and turbocnc. I managed to get the circles out of the simulation in bobcad by changing various g code settings but the circles should up in turbocnc.

In BCC you will have to open the CAM side of the software and select a post processor. Go to Setup>Driver>General and select the way your machine controller uses arcs. Save these setting for that post processor and regenerate your tool path. This will fix that problem.

thanks for the info, I will try to find one that works with turboCNC
