I have recently converted my Jet 13x40 lathe equipped with DMM Tech servos from mach3 to mach4. I have the DMM servos, BOB and drives work with Mach4 and the Smoothstepper. Homing though isn't working right: X axis homing works but Z does not. I have the same setting in Mach4 for both axis except for the pins and name: Pin 10 for x homing/limit and 12 for z homing/limit. In diagnostics, you can see the lights work when you trigger the limit switch but when you try to home, Z homing does not work. It tries to home and then stops and does not back up, like x axis does. One other thing is that Z axis(Lathe profile) jogging is backwards when I push the jog buttons on the display with the mouse. x axis is proper direction. I don't know if these things are related and really am frustrated at this point.
Other than the homing issue, I am really liking Mach4. I was able to cut a 1/2-20 thread- made the gcode with fusion360 and everything cuts well but the Homing issue is driving me nuts.
Any suggestions would be greatly appreciated.
FYI, here is the conversion thread when I set up the Jet lathe to cnc and Mach3:
