hello, how i can resolve this problem.
I need controlling the turret without stops.
you have some idea?
Thanks in advanced.

Luis, without providing more information about your machine, your turret, how it operates, we won't be able to give you much advice.
Post pictures, of the turret, is it something you made or something that was made by the manufacturer of the lathe, how does it work etc

And here is the code we are using. Running this via MDI always 'resets' the distance to go to 0 for the A Axis. Running it in a program, does not, so the calcs do not remain consistent. M0 in the code, or in the macro, solves the issue but the machine will wait for cycle start on tool change.

Hi
Can anyone tell me if a solution to the "distance to go" issue as described in this thread and above has been found, other than to add an M0 in the code ?
I'm trying to get a home built ATC working with this macro and found this thread after hitting the exact same problem , everything works fine with tool commands from the MDI but when i run intercon generated code with multiple tools it falls over.
This is the code.
Thank you very much if anyone can help me.
