This is the G-Code generated by Jon's Makebore program that uses I J for the

The attached screen shot shows that LinuxCNC chokes on this. Suggestions as to
why?

Classic LinuxCNC problem, the G-code only has 4 significant
digits on the I and J words. LinuxCNC checks for 6
significant digits. That's **WHY** I always use the R form
of arcs.
Or, there is a parameter to reduce the precision of start
and end radius matching.
