Hi,
I have a Taig CNC mill with Deepgroove drivers and 253 oz steppers and run it with Mach 2. Now I need to cut a part that requires using the A axis rotary.
First question is: How should Mach 2 be set up as far as motor tuning goes?
Should I reduce the steps per unit until I get one full revolution from G0 A360?
If that is correct it would be something like 4.44 steps per unit, since I work in metric. This would not give very smooth contours due to poor resolution.
I am trying to cut an o-ring groove on a cylindrical face. The cylinder is mounted in the rotary chuck which rotates about the X axis. I want it cut so that the Z barely moves. This means that Z goes down to its cutting depth and only Y, X and A moves simulateously to cut the groove.
I have tried using 4th axis rotary toolpaths is Master Cam X, but it only allows a ball cutter and keeps moving the Z up and down. In the MC reference manual they recommend using C axis toolpaths for things like engraving on a cylinder face. Engraving text or an oring groove is the same so it should work, but this is limited to only the C axis.
Any help is greatly appreciated!
