CNC Code troubleshooting

I keep getting the error "Radius to end of arc differs from radius to start on line number #15"
It also gets that error on lines 20 and 25.
I am trying to cut a disk 7 inch in dia with three passes of 0.26 inch at a feed rate of 5 inch per min. with the center of disk at x0, y0. and a bit of .25 dia.

Try changing your IJ mode. It should be set to Incremental, and it's probably on absolute.

here is the corrected code, I also ran yours in ncplot

Gary, there was nothing wrong with his code. His IJ mode in Mach was set wrong. It's supposed to be a circle, not what your picture shows. His code runs fine here.
