Bought two of these to try sort out some issues I was having with my Voron, and man do they perform. As a drop in replacement They upped my seed from 200 to 500mm/s and fixing the problematic bearings and racking in my gantry allowed these guys to go up to 800mm/s without any really attempts at tuning.
I'm really impressed.
