Hello I am using bobcad V23 and a desk cnc controller. I am trying to cut a circular pocket and keep getting the "current point same as end point of arc" message when I load the gcode in desk cnc. it gives this error code for line N07
I have tried usng a contour as well as just a circle drawn with coordinates from the menu. I keep getting the same error. It will cut other shapes fine just no circles. Anyone have any idea what the issue is? Thanks Chris

The problem is that it can not interpret the center with info provided. You either need to piece it as 2 arcs or use I and J data. I is on X axis and J on Y. They are incremental from the current point(start of that block).

Try changing these, assuming the arc cener is at x0y0....

N07 G3 X.001 Y0 I-.001

N09 G3 X.006 Y0 I-.006

N11 G3 X.011 Y0 I-.011

You can open your post processor in notepad and look at lines 223 and 221. Try setting either or to y and see if the arcs run then.

Thanks guys. Bobcad got a new post processor for me today and it is now working. I do not know exactly what he did but he mentioned changing the arc's to incremential.
