48V Duet3(4?) to complement future Duet Motors?

@jay_s_uk
I'm using a separate 48V supply on my CNC, too. I always forget to switch it on before powering the 24V PSU. The TMC5660 drivers don't like it and quit responding.
With a boost converter, I only need one mains-socket/cable/switch...and ground-loop issues are no problem anymore.

@o_lampe the resistor does not, but the insulation may!
