servo control vs stepper control

[JAZZCNC]

So from that I gather that whatever voltage I use to power the BOB, that's the signal voltage sent to the drive? Will that BOB linked in post 3 definately run safely off 24v?

I wasn't referring to that particular Bob or any Bob really and so obviously it would need to support 24V but most decent Bob's feature a range of input voltages.

I wouldn't use a cheap BOB with quality Servo's and to me this BOB isn't really a quality Item, it doesn't have a Charge pump for one which is nice feature and it looks a bit small and cramped.
Cheap nasty BOB's are a pain in the arse and a large source of problems and they don't always show has plain "works or doesn't" so can cause any thing from weak signals to dropped signals to slow acting Opto's etc all of which if your unlucky to drop for it will drive you crazy. .
