Rambo 1.4 power supply to Duet 3

[Theboz1419]

Just when I think I have asked all the stupid questions, I have another.

My Rambo 1.4(24v) board has 6 wires from the power supply. The supplies are separated into Heated bed, Logic, and motors. The Duet 3 is just looking for 12v-24v +-(two wire connection).

How do I go about wiring this up, correctly?

@Theboz1419 I assume it's a Duet 3 Mini if it has only two VIN terminals. In which case, you can just connect the 24V V+ and V- terminals of the PSU to Duet VIN+ and VIN gnd using two wires.

If you want to use the same PSU output cable, first make sure that all 3 supplies are connected together at the PSU end (i.e. the PSU provides a single output, not 2 or 3 separate ones). Then crimp the 3 ground wires into one fork terminal and crimp the 3 positive wires into another, and connect these to the Duet VIN terminals.

If it's a Duet 3 MB6HC then that board has a separate VIN input for the bed.

@dc42 wow, I am actually impressed with the Duet Forums. The quickness of getting answers to questions is awesome, Thank you.

I have the Duet 3 mini wifi. I figure that was probably my answer to my question was to just group them up, and if I had my multimeter available I probably wouldn't need to ask the question, but I wanted to be sure or it was going to drive me crazy and I wouldn't get much sleep, lol.

Thanks again for the fact response
