I could have sworn I found info regarding this, but can't find it anymore.
planning on getting some 850oz DC Servos for the X/Y Axis on my zx45. Keling seems to not have any 90v for a while, I asked him if he would be getting any in, and he told me that the diff between 72v and 90v models wasn't significant.
I am getting an 1125oz for my Z but then I ponder the same issue.
Any thoughts?
