Hi everyone. I have a problem and I hope you can help me I need to buy a new extruder for this printer, but the ones I find are 12v, and the power supply is 24v. The seller of aliexpress says it works ... but I keep thinking that he just wants to sell ... Is that so? Does it work despite being the power source of twice the power? Won't burn? I wait for the answer, because I am desperate ... Thank you all!

You 100% need to match the correct voltage otherwise you will run into a lot of trouble. So don't do it.

Oh, it's ok. I thought the same thing. Thank you very much for answering

I was running 12v heaters for a long time on my 24v power supply. I then realize that they were 12v because I got around to measuring the resistance. The caveat was that in Marlin I had to turn the max power way down because at full power it would over shoot and go into thermal runaway during the PID tuning. So it is possible but they heat up crazy fast.

It was set way low.
