Is it possible to use external drivers with the Rambo v1.4 board? I really like my MPCNC, but I’m building a different CNC machine. I like the dual end stops and I like that in the future I could use more than 3 axis, so I’d like to re-use the Rambo v1.4 and firmware but upgrade to larger motors, but I wasn’t sure if it’s possible to use external drivers with this board. The motors I want to use are NEMA 23 175 oz*in with 2.8A/phase (12-48VDC). I don’t think I can use them with the since the onboard A4982 drivers seem limited to a lesser amperage. I can’t really find good information on this so I’m not positive.
To be clear, I understand that NEMA 23 is only a mount size, but I do want higher torque motors than the original MPCNC motors because my new machine is beefier (it’s a gantry design with ballscrews and linear rails).
Does anyone have any experience with this?
