hi all,

seem to have a problem with a Boxford 240 cnc retro.

ill try and keep this short.......

got this lathe all kited out to run with mach3, still had the original steppers on it. every now and then the X and Z stepper would stall. i played around with a few things and finally it stopped stalling. about a year later they started stalling again. thought i would fit new steppers and a new higher voltage power supply to run them. when all done the X and Z are running much better and no stalling.

it was then decided to fit a new pc. Mach 3 was loaded up on the new pc with the old pc's mach3 profile. hooked it all up, everything worked fine........ but now the steppers stall worse then before. put the old pc back on and all is fine.


as far as i can tell (in Mach3) everything is the same and i didn't need to touch anything in the lathe....... it's just a new pc.

any help would be much appreciated.
