OK, I would have expected it to just move 1/4 turn.

The code you have shown may need a tweak

G00 G90 A0.0
Y-30.1 X0
(This program has No Z moves!)
M98 (Index.tap) L20
M5 M9
M30

Try it like this and let me know how it has changed

Not sure what you are saying, have you set your datums?

OK,

What happens if you type  this code into MDI

G00 G90 A90.

put a sample of your code here for me to look at.

Cutter comp is at the top of the to do list according to Brian.

It's cutter comp, not comp / pocketing / magic bad code correction.

It's hard enough to just get it to offset correctly. Comp shouldn't try to decide what I'm trying to do, it should just offset the coded path. That's it.

Yea but look at the picture in my last post. It did it wrong. I gave my Opinion on how to make it work correctly. What is yours?

I am afraid you did it wrong,  there are rules with any form of machining e.g. you have to drill the hole before you can tap it.

Well tool radius compensation is the same.

The golden rule is that the tool must always travel in the same direction tangent to the part, it must never reverse its direction, this means when you are working with angles less than 90 degree the point must have a tiny rad on the end, if not the path stops and the direction is reversed.

Hi Guys

after much experimenting I now have the same fault as you do, the difference was I was running Mach in Metric and entering metric values e.g. .02mm , running it in inches gives the same fault.

I am in contact with Brian about this, so we will see what he has to say.
