Yeah, thanks for the offer.
Been looking at drives, I know these are cheap for a reason but surely they should work?
I still don't know if the signal quality is an issue.
It runs fine open-loop so its definitely encoder related.
I have no other drives to try out, if i was to buy another i would have to be 100% certain it would work first and it would need to be affordable i.e. probably 2nd hand.
I know this issue popped up on my first build, checked the thread but cant find it, i think it was when bench testing a drive and CSMIO - it would fault out but back then i put it down to lack of set up etc, since fitting on machine, none of the drives have ever reached full speed so the problem never returned.
Doesn't help but i'm sure it happened.
