Hi all, just would like to know the following if anybody would be so kind to help as it would be truly appreciated. I am now at a stage where I am tuning the motors in Mach 3 but things are seeming extremely difficult to proceed as I am doing it step by step and its just taking forever and I have searched high and low and would like to know the answer to a query. I have a bi-polar 3 axis drive combo type and it was from the Alien CNC guy which I bought about 4 years ago and on it it says 1/8 microstepper, now I have 8mm threaded rod as my leadscrews on all 3 axis and need to input in the Mach 3 section where it says motor tuning and set-up the Steps per inch and do not know what or how to work this out, what would this be ? also what do I input in the box where it says Step Pulse and Dir Pulse ? my motors are Nema 17 type ones if it helps. I would appreciate any help possible guys as I'm nearly there but not quite....... Kammo1.
