Just so we are on the same page the latest version is 1.8 http://wiki.linuxcnc.org/uploads/arcgenm18.py
If your not in the correct starting position then you will get an error for sure. For example: center X0 Y0 diameter 0.275 start angle 90 end angle 180 direction ccw gives me a start point of X0.0 Y0.1375 the arc G3 X-0.1375 Y0.0 I0.0 J-0.1375 so if I run the following in the MDI it just works F25 G0 X0.0 Y0.1375 G3 X-0.1375 Y0.0 I0.0 J-0.1375 JT On 12/6/2015 5:53 AM, Gene Heskett wrote: > On Sunday 06 December 2015 06:27:37 John Thornton wrote: > >> The default behavior of incremental. >> >> JT > I was rather convinced of that.
