If your using G91, then prior to line N5030 the tool needs to be positioned on the arc. Line N5030 would be G3 X0 Y0 I-.36 J0. Realize that I is saying the arc center is -.36 from the X cutting position.

Example:
G90 G1 X.36 Y0
G91 G3 X0 Y0 I-.36 J0

or

If center is not X0 Y0
G90 X-- Y--
G91 X.36
G3 X0 Y0 I-.36
G1 X-.36

If this helps, super. If not, just give a holler back.

I, J, & K are always incremental values. When used in arcs or circles, they represent the incremental value of the arc start to the arc center. Most arc errors are because these values are not correct in relation to the arc start.
