Drag Knife
« on: July 27, 2012, 01:04:17 PM »
I know mach 3 has a macro for using a C axis drag knife.  Why question is if you are cutting a start shape.  All the video's I've seen show cutting profiles like an ellipse or arc.  What happens when you cut straight lines at different angles.  Will the C axis align with the cut for each line of a star.  Tool up over down, cut line, up rotate down cut line etc etc.

Any information on this would be great.

I think you are referring top a tangent Knife function not a drag knife. The drag knife is free floating for rotation. The tangent is axis controlled and follows the direction of XY movement.

Just a thought, (;-) TP
