G90 is absolute movements.

G91 is move incremental.

G43 is use height offsets, only if a Hnn is commanded.

Its not as easy as it looks, you need to know a lot about what is coming up in the next moves, e.g. look ahead. You can't do this with a macro or g-code.

Also what if the rad is too big to fit in the V.

I once asked Art for auto rad and auto chamfer,  I think he is still laughing about it now.

Have you tried it with a feed rate in the line "G91 G01 X-5. F10."

What G40 question, I must have missed it or lost track of it.

Hi Olf20

G00, G01, G02, G03 are known as modal, they are in effect until another is commanded or a G80 is commanded.

Rapid setting are set by the motor tuning.

I think it is the fact that you are using #9001 and above, these are normally used by the system and may be getting corrupted. Art gives no guarantee that the # numbers work in all conditions.

You can use the G52 with # numbers

E.g.

#1=100.125
#2=120.000
G52 X#1 Y#2

I would keep away from the 9000+ numbers

Are you wanting to put a rad on the edge of the bore or on the grooves?

Try this version, but change the tool dias in the marked lines.
