Is there a way to run a 24v heater on a 12v duet2?
-
I'm finding the 40 w heater is just not enough and want to go to 60w but the heater suppliers only sell a 60w 24v heater (revo). So the 40w cant keep up and i get heater faults when using larger nozzles. I have the mini board attached (dont know what its called) so the power is not coming off the duet board (i think)
-
If you're going to go to the trouble to add a 24v power supply just for the heater, why not just convert entirely to 24v? Your motors would run better off 24v as well.
Take stock of all your 12v components and determine which would need to be replaced as well, like heaters, or which could be fed by a buck converter, like fans.

@Phaedrux Well yes, except thats 7 or 8 motors plus a new board and a new extruder, I could use a new board i guess since none of the fan outputs work, its happened on all 3 duets i've bought. I dont know if that has been fixed but i sure dont want another one like that.

@brian why are you changing your board and motors???
It's only the heaters and fans that are voltage specific on most 3d printers -
@engikeneer Really? I thought when i bought the board i had a choice 12v or 24v. Wow, that changes everything. So would i just get a 24v power supply and everything would run?

Yes. As @Phaedrux has said, your motors will run better in that you could drive them faster before torque drops. If you have 12v fans you will need to set vfan jumpers accordingly or use buck converters. On no account use 12V heaters because the stated wattage will be 4 times higher if you "feed" them 24V. Sensors such as thermistors, end stops etc are unaffected by whichever Vin you use.

@brian As deckinman says the only parts that would need 12V are the fans and the heating elements. Fans you should be able to set the jumpers for or use buck converters but the heating elements need the correct voltage. Since you want to change to a higher hotend heater that is easy. Just buy a 24v 50w or higher wattage heater. And you can keep your original heated bed. Use the original 12v power supply for it and add a heated bed mosfet. That is just an example of one. And wire it in similar to this. I would add a fuse rated slightly higher than the power pulled by the heated bed too. Or spring for a 24v heater and enjoy faster heating times.

@gtrider Thank you. You have also made my day.

@deckingman Thank you and the others, you have made my day, saved me a lot of stress and money.

@Phaedrux Thank you. Never heard of buck converter, so thanks again.
