Bug using G68 with a angle probing routine

[Delco]

I have been using a G68 routine for a while now with V1.2112 , been going fine doing a angle probe in the Y direction with clearence in the X direction to give me a angle value that the X axis needs to be rotated.

I have found if I put a 123 block down and rotate it approx 30 deg and probe for the X rotation it shows a value of +30 deg ( which is what I enter in my G68 macro ) , but if I probe for the Y rotation it gives me -30 deg .

now assuming I am using the corner of my 123 block as the axis of rotation if I enter G68 X0 Y0 R30 as expected the function works perfectly , but if I enter G68 X0 Y0 R-30 after probing the Y axis it is in error.

I am looking at this wrong ? or is it just a overlooked error ?
