Hello Team,
I am a newbie and I would like to ask for your support.
I have a SKR PRO 1.2 that I want to connect to 3 NEMA34 motors using HBS860H drivers. I cannot find a similar setup, so I would appreciate guidance. I bought a Mellow 5V Motor External Driver Adapter (with 6 pins) but it still doe not work.
1 - Are the SKR PRO 1.2 and the HBS860H compatible?
2 - If yes, how should I wire them?I am adding some photos for your information.
Thank you for your support
Hey Chris, that is an absolutely unusual setup around here, there are only a few users who use external drivers and most of those do use different boards (I use an EstlCAM board for instance).
I use closed loop steppers as well though, and I would definitely not use the ENA pins.
Hello, Chris. None of the V1 machines are designed for NEMA34s.
If your project needs those, you might want to consider a controller that already has support for external drivers (there are good boards in the FluidNC ecosystem).
To answer your question, when we’ve had users try to pull the drive signals out of SKRs in the past, they used adapters like these for the signaling:
