Alrighty....I have a little issue with getting my motors tuned in Mach3. This is actually on my Clausing lathe conversion. Here is what happens:
I can get my motor set to move exactly short distances (.5, .625. and .750). But once I try a longer distance (6"), it moves .020" too far. If I get the steps set to get the longer dimension right on, then the shorter travels are off by .002 too short.
I am sure I am missing something simple here, but I cannot figure it out.
Oh...and just out of curiosity, I used the milling module and used the automated tuning feature....same thing happens.
Any ideas?
Mike
