Hello Chaps,
Mach3
this has happened to me at least twice in the last few months
when I switch the system on i find that one or both steppers have changed direction.
I dont know - maybe someone can throw some light on the subject.
We have been experiencing a lot of mains power outages.
In order to alleviate the situation I have installed a 60KW 3 phase generator set .
could this have something to do with it? maybe phases mixed up?
any discussion will be welcomed
regards fred
