Hello,
I run a rumba board in my 3D printer. The heating bed is to be operated via a solid state relay ("bang-bang" setting).
HB-OUT is connected to the relay input. The heating bed is operated externally via mains voltage.
Do I still have to connect the 24V power supply with HB-PWR?
Attachment: This is my current cabling.
