I am dutch and i have a problem with the circle.
The I or J = 10 and the diametre is 20 mm but i get 22.2mm, if i use I or J 15 then i get 33.3mm.
When i do it with a trangle it is oke, everithing is fine, the machine is working correct.
i have switsch of the compensation so this is to not the problem.
What do i wrong.

Theo,
It sounds to me like your steps per are off. By 11%.

Are the scaling values set to 1.000?
Are the circles round?
If you mill a 25mm square is it size and square?

Thanks, the steps per unit was wrong, i used the Step per units that caculates the units but is not accurate for my machine.
I hava a 4 motor router and the X and A and Y are the same units but the Z differs from the others. Stange the have the same TR12 ax and nut.
So how accurate is the calculation or is there difference between a drive from only X or X A at the same time?
I dont now but it works,
Have a nice CNC day
