Gentlemen,  I've adjusted the SS filter(s) down to 1.43, confirmed wiring OK and switched axis' to track problem and....... I've still got the problem!

It seems to me the problem is upstairs in Mach3.   Once again if I press X+ repeatedly the motor will change direction in a random manner. ???

Upon Homing, Z/Y perform flawlessly and when X ho,ming begins the motor just sits and growls, like its getting X+ and X- instructions at the same time.

Ok not sure what gets swapped out when you change the plugs on the G540 but can you try swapping pins in Mach and see. Say for example you change the pins around for X and Y, see if the Y now loses the plot or if its still the X that has the issues.

Well,  reversed the Motor Output pins from X(2,3) and Y(4,5) to X(4,5) and Y(2,3).     Manual actuation changed on the keyboard - previous X arrows and Y arrows swapped functionality but random direction changes remain on the X stepper (albeit somewhat less frequent which doesn't make sense to me).

I guess I'll re-inspect all wiring points and await another idea...

Cheers

Thank you very much for your responses and help!!

Lastly, can you point a Newb to a thread where I can learn how to get her milling?

Cheers to all,  Scott
