Just as a heads up as it's common Gotcha.!! . . . One thing to watch for with these Controllers is you need to check your drives are using the same Step edge otherwise you'll lose a step on every direction change.
The IP-M is set to leading edge so check what the drive is set to.? Can't remember what drives your using and can't be arsed to go back searching but if AM882 or EM drives then you can change the Active edge in software and possibly using Dip switches but can't remember.
Some drives don't give this option but it's not a problem as you can just change the Active edge state in Motor outputs. Thou it doesn't work in usual way Mach3 does and reverses motor direction so if you need to reverse motor direction then use "Reversed" in Homing limits.
Best thing is to test by righting some g-code with lots of Back n forth moves and check the axis returns to same spot.Last edited by JAZZCNC; 23-03-2015 at 01:40 AM.
