Hi guys, did you ever resolve this? I'm going through a similar issue. Thinking of running 24V to my 6HC and 48V to the expansion board (3HC). Will this work? New topic posted here:

Thanks 🙂

I don't have any particular complain about the connectors, I'm pretty easy going on that regard. The very small beige ones are tedious to crimp but fortunately I've purchased the wire-kit.

I know it's already pretty small but what I would love is for it to be with one side 40mm max, even sacrificing a connector (or using a smaller one) or dropping the switches.

I'm doing a magnetic toolchange with very small heads and I'm having troubles positioning the toolboard (I'm actually thinking of using an expansion 3HC instead of the toolboard).
