The problem is this fresh air arc move 15mm above the workpiece, I cannot see why it is there

(Line 12 onwards)
G0 X 23.158 Y 23.244
M3 M8
G1 X 24.926 Y 20.062
G2 X 18.562 Y 20.062 I -3.182 J 3.182 <<<<<< offset is less than radius of cutter
G0 Z 0.000

All the actual cutting arcs are fine, with offsets larger than the cutter diameter, never mind the radius.

The file was obviously generated, you just need to tweak it so that the cutter descends to start cutting without that little arc move

If you get an error other than on line 17, you need to make sure your tool table is set correctly or use G42.1 D7 to set diameter in the code
