I dont see a benefit in a hybrid stepper anyway. Prefer servo motor or a plain stepper.
Sorry I bothered to offer an opinion. Seems you have an expert here who knows all the answers!

It didn't know that "it must be driven at 70VDC and 4.5A" - that must be a universal truth I wasn't aware of. Sounds as if it will be a hell of a beast. Motors as big as the machine itself.
