Gentleman,
Just bringing this back up to the top to see if anyone has any input. I know I'm not the only one running Mach 3 with a 4th axis and others have had plenty of success.
Any thoughts as to what I'm missing?
To add to the discussion, when the CAM does a movement that requires a rotation and a gantry move, it doesn't move in sync. What I mean by that is say I cut an opening normal to the surface at A0, Y0 and then move down the tube 30in or so to cut another opening at A300, Y30. It should rotate smoothly while the gantry travels down the tube such that it gets to A300 and Y30 at the same time. What happens in actuality is the rotary smoothly rotates while the gantry moves, pauses, moves, pauses, moves, pauses until it finally gets to A300, Y0. The machine does get to both points at the same time but it is not a smooth motion.
I have do a lot of 3D contour work where all three axes are moving concurrently and never have problems. Something with the rotary is preventing it from kicking out the right thing.
Thoughts?
Thank you,
Lee
