Gcode error in program

I am getting this weird error. I think I know what it is but i think linuxcnc should allow it.
My post is doing a pofile but not closing the vector because I have the parts so close together, the post algorithm is such that it deals with it in a way that linuxcnc doesnt like. see pic of sim in cam. (bottom part).

linuxcnc 2.6, I'll try it on 2.8 tomorrow and see if it still behaves like this. Maybe the old trajectory planner?

Nope, this is an interpreter-detected error. When you use the I J arc form, then the distance from the center to the start and the end of the arc must match to a fairly small difference. The error shows a quite large difference between start and end radii of
.009 units (not sure if you are using inch or mm)

I don't use the I J form, I use the R form for arcs, where it is impossible to have this problem.

Your CAM software (post processor) may have an option to provide more decimal places for the I J words that may solve this problem.

Also, there is a parameter setting that allows LinuxCNC to allow more error in this.

I decreased my ramp from 1 inch to .5 inches. Then it ran ok.

Thanks for that clarification Jmelson.
