@Maestro would it be possible to use this type of connector? Like I conenct the one u cable to the psu and connect this to the wago connector, which is a 1 in 2 out? Would this work? Does the psu also pushout the wattage go to each cable? Like here, https://www.amazon.com/GKEEMARS-Electrical-Connectors-Splicing-Terminal/dp/B09VRTBFTT/ref=mp_s_a_1_3?crid=2916GR814BXLZ&keywords=9+wago+connector+1+in+2+out&qid=1689177809&sprefix=9wago+connector+1+in+2+out%2Caps%2C241&sr=8-3. Would this work?
I am hoping to use a 600 or a 900w power supply. So I don’t know if it would short out the splicing terminal.

Thank you for all of the suggestions!

@Maestro ohhh so like over lapping the power cables? That makes more sense, like if I take the one positive terminal, i could over lap cables from the terminal or from the board?

Thank you for responding!

Hello!
I have one question that I've been trying to find online but I haven't been able to figure it out.

If I wanted to have more than 3 boards as you need 1 positive and 1 negative cable for each board and a usual power supply has 6 slots, 3 positive and 3 negative. That would only be able to supply 3 boards, right?

How would I go about adding more boards with my power supply?

Would I need a second one if so?

Thanks for your time!

@SageAardvark in my response here I made a slight mistake. I meant that the board that I was thinking of using only has enough room for 3 extruder and 3 temperature sensors as I know of. The board wouldn't have enough slots for all of the extruders so is there any boards that I can use that would have 4 extruder slots or expansion boards I could use. And would the Duet 3 3hc have any slots for extruder heaters.

@dc42 They are probably going to be nema 17 motors. Just so you know I haven't fully built it yet but I have been trying to do a lot of research so I know what to do when I get it, the extruders may be run by a direct drive or it might be a bowen setup. Ill have to so a little modeling if i wanted to try and see if it would work. Thank you all so much for your help with this and taking your time to respond.

I hope this information helps

@deckingman So to connect both duet 3 3hc daughterboards to the mainboard would I need to use a tool distribution board for it? And then as you mentioned I wouldn't need to have an extra power supply so I would have to connect a positive and a negative cord to the tool distribution board and it should power all of the daughterboards? I again am very sorry as I am very new to this. And then plug in a positive and negative cord to the Duet 3 6hc and it should completely power that board?

Now, I am very noob to this so I'm sorry if I make a mistake anywhere.
I need to make a 4 idex extruder set up with 4 motors moving the extruders and 4 filament motors with 2 motors for y and x axis. I have been looking and I've noticed that all of the motherboards that I've seen only have 4 extruder plug ins.

If anyone can suggest some daughter and mainboards for the project that would help greatly. The motors I am using is a 42-40 regular motors unless there are better ones that are stronger for the z axis.

I am not sure how I would go about wiring for all of the motherboards (main/daughter board) I am not sure how I would wire with 2 daughterboards with one psu. If I need 2 power supplies how would I go about that and connections. I understand how to wire the main boards but unsure if I need 2 psus or if there is a way to have more connections for power as I am new. If anyone can reply with some diagrams on how to wire them that would be very helpful.

Thank you for your time!
