Bill, I tried the following (12mm Dia tool)
N7 G0 X-11 Y23 N8 Z25 M8 N9 Z21 F1500 N10 G1 Z15 F300 N11 G41 Y14 F1500 N12 G17 G3 X0 Y25 I-11 J25 N13 G1 Y40 This went wrong! It should be a move down and then a 90 deg CCW arc to the edge of the profile except it moved down and then done a CW arc! It is explained by observing the first move down to Y14, it ended up with the centre of the tool at X-5. It applied the comp to the first line rather than at the end of the first line! It is a rather old (and odd) controller!!
