Ok, I know I can be a bit dense at times, but I think I finally have it. All you really want to do is jog x,y to a point, fire the trigger(this will invoke cycle start or run), a program will run in mach, when done you will jog to a new position and run again. And I get that the trim will be used to set the full scale speed of for the stick. ie: trim in 1 position, full stick may be 200pps max, while another position will be 400 pps max. full trim will set full stick to 6000 pps max, and all the numbers in between. Do I finally have it?

I think with a small bit of rearranging, my posts still apply in concept, just not in operation. I did realize the person is closing the loop, but I know on my mills and lathes, it it far too easy to jog right onto a limit, without which it would crash.

What I did not realize was you are planning to have mach still be able to run also. To me, the software side for the pic is pretty stright forward, but I am not sure how you will interface the 2 (joy stick and mach). How you will be doing this might have bearing on your program.

After you have time to read over all the babbling I did, feel free to keep asking questions. I enjoy helping on things like this as I love puzzles.
