Hi all,

I've retrofitted my old Meyford lathe with Mach3, after I've successfully used mach3 for a small CNC router. Now I'm having some very strange behavior:
The direction of the stepper motors sometimes changes. So far I haven't been able to find any regularities for when it changes and when not. Once it changes thoug, it seems as if the motor axis direction just has changed, so jogging will make the motor run in the wrong direction. Thus far it seems if I turn the machine off and on afew times it resets itself. I really don't know what to make of this. Any help would be greatly appreciated!

Thanks!
