    Does it have to be exactly the same? Can't you ge one that's the same spec but a different make? The BOB will not care what make it is as long as the parameters are the same for voltage and amps etc. etc?

    Moons SR4 is just analog 24-48V stepper drive capable of running motors between 1 to 4.5A so any make will work just the same and probably cost less.

    Personaly if replacing I'd take the opportunity to upgrade to newer digital drive for better performance.
