Hi,
Is there any preference of USB or Ethernet to interface the Smooth Stepper?
Ethernet most certainly, aside from the fact that the USB connected SmoothStepper is no longer manufactured.
Do you have any recommendations on what break out board would be best suited to this controller?
Many are opting for the three port MB3 from CNCRoom. Its not cheap, but a good balance of input/outputs and well made.
Another alternative is either one, two or even three C10's at $23.00 each. They are single port bi-directional BoBs. You will be
required to add a little circuitry if you want opt-isolators or relays for instance, cheap but flexible.
I will be using a Proma 150 and DM542T drivers.
The Proma is suitable for use with Mach3 but a poor choice for Mach4, and you really REALLY want the THC and anti-dive that
a TMC and Mach4 give. All development on Mach3 ceased six-seven years ago....don't saddle yourself with an out-of-date software system.
It looks like the board is available with either a ribbon cable or screw terminal interface
The ESS has ribbon cable output ports only, they connect to one or more breakout boards. Its not recommended to hook direct
to the ESS, always via a BoB which will typically have screw terminals.
