Hi All,

I have upgraded a Denford ORAC lathe to work with a Pokeys57cnc card and Mach4. All the basics are running very well. Then I also would like to use an A axis for a rotary 6-station tool-changer. In principle that works as well but the rotary tool-changer has a ratchet-lock and can thus only move from one tool-station position to the next in one direction (say clock-wise).

Then inside my M6 or T macro: Say the current tool is 2 and the next tool is 1 it should move clockwise (360-60)deg to get to position 1 but the mathematics wants to move from position 2 to position 1 using the shortest path, that being anti-clockwise.

Any ideas how I can force it to only move in one direction would be highly appreciated.

Kind regards

i have Luxturn lathe with 8 tools. Toolchange only in one direction allowed.
I have M6 Macro i can send you. You need to set rotary Axis as C not A.
