I'm still futzing with these motors..., I know this is an old thread... but I'm trying to run these steppers with the FET3, which has the upgraded high power mosfet's to handle up to 15amp's per phase. If I'm correct in my calculations, 4.7A per phase, 2 phases per motor... so that's 9.4A per axis that I would need which equates to 28.2Amps that I would need minimum so a 30Amp pwr supply should suffice .... right ? No matter how I've set this up, I end up with a condition like the steppers are connected wrong, just doing lots of humming and buzzing, not turning..... symptom that tells me that I've got the phases wired wrong, but I've gone backwards and forwards with a bunch of wire configurations and can't make head or tails out of it. Anyone else have this problem / issue with the FET3 Ctrllr ? Should I just bite the bullet and just get a Xylotec controller... ?
thanks,
Art
