Is it possible to use the 3D circular interpolation function to make a 2D circular interpolation for example for a XZ cartesian robot or I must use the 2D circular interpolation functions?
Here you have my code: if I run it for the 3 axis intepolatin plane XYZ is working good but I get an error when I run it for the 2 axis interpolation XZ
// Circular Interpolationplane XYZ
IF I_KinPlane = enXYZ THEN

I did some tests with following results:
Working:
Not working:
I added my test program here so you can open it.
In short: For commanding an 2D kinematic an 2D circle commands needs to be used.
In long: A 3D circle is not possible to use with a 2D kinematic, as the calculations are done 3-dimensional and so 3 coordinates are expected, but the transformation is not supporting 3 dimensions so only 2 coordinates are useable.
