Hi Guys
I decided I wanted to upgrade my nema 23 425 motors to nema 34's. Figuring it would be a simple job I went about ordering new motors and fitted them today. However since fitting them it's taken my machine out of action.
I have leadshine dm856 drivers hooked up to 48v power suppliers. Prior to the switch I was able to jog at 8000mm a min easily enough. Now I can't go past 500 without jamming. Acceleration is set to 50... steps haven't changed and it's a 1605 ball screw machine.
These are the new motors:

I feel like I'm missing something, but I'm not sure what...
I have just a single motor connected to X at present...
If I jog it just seems to jam up
