Sorry to post again, but a new title might get a better response.

I have a 1980s CNC milling machine which I'm fitting with new motors and electronics. The original motors were 3.2Nm and I have sourced modern Astrosyn 3.8Nm 4.8V 2.8A.

I know several members of this forum are keen on Leadshine drivers so my question is which driver DM542, the DM556 or the AM882? The latter would be a bit of pain as I'd have to buy higher voltage power supplies (I have 36v).

Any preferred seller for the above.
