Hi. I'm trying to control a cutting knife using the Tangential Control feature in Mach3.
Everything is working well with one exception; at corners in the cut geometry, where the A axis needs to re-position to be tangent to the upcoming XY move, the Z lift and A re-position are a blended movement.
Normally, as with a true milling operation, this isn't an issue but in this case the knife I am using has an offset blade tip. So, when the Z begins to lift and the A begins to rotate, the tip of the blade is dragged through an arc gouging the material. What I need to for the Z axis to lift to zero and then rotate the A.
I can't figure out how to do this. Any ideas out there?
Thanks.
