I am using the Archim Rambo 1.0 board which has the extra 2 stepper motor controllers. I have a project that I would like to do that would require a 2 axis rotary table. I was looking at this one on ebay. One issue I am worried about is that it is a Nema 23 vs the Nema 17 that the MPCNC uses. I am worried if the stepper controllers on the Archim will have enough power for these. I am planning on working with wood, so would not need the full torque. But I noticed the archim board has 4 high power Mosfets, and 2 low power Mosfets. Are these related to the stepper controllers? And if so does that mean that one of the 5 axis on the archim board will have a low power Mosfet?
The archim 1.0 uses the DRV8825, which is good for 2.2 max amp, 1.5 continuous. I think most mpcncs drive their nemas at somewhere between 0.75 amps and 1.1 amps with no problem. Hard for me to imagine 1.5 amps not being enough, but I haven’t used any 23s either.
Thanks, looks like the 23’s would like 2.5 amp, but I do not need their full torque so maybe I will just try it.

What firmware are you going to use to drive it? You’ll need A and B axis for 5 axis Marlin supports E, but it is mixed up with all the filament features.
CAM is also a problem. I have heard fusion can handle 5 axis milling, but I am not sure what license it needs, or what post processors can handle it.
I would start with the CAM, and then try to work out what firmware supports that. Hopefully LinuxCNC or else Mach is probably needed.
1.5amps is pretty enough for your purposes, don’t worry
It’s essential to ensure that your stepper motors are compatible with your board and have enough power to move the rotary table.
