Hello

It is not so easy to switch from IJK (Circle Center) to R (Radius).

First read the Controller Manual.

If you want to Output Circle with Radius than you must consider following conditions.

Arc angle < 180°  Radius is positive  +R

Arc angle > 180°  Radius is negative  -R

Arc == 360°  not possible.  You need to split the arc

Also some Controller does not support 180°

So you need here also a workaround.

If you use PostConfigurator you only need to switch

"Circular Move Always with IJK"  to off

Regards

First you have to generate your Post with PostConfigurator.
As i see you are working with PostBuilder. This is not the same!!!!

Solution Partner Phenom

in Postbuilder just:

1.remove IJK,

{you can force XY R}

3.switch full circle\quadrant - and test both settings and use working one.

I have no problem with this.
