@Phaedrux Hi yes i saw this option, but in this case i need more of this lm2596 modules and i already have a 12v power suply and i was wnderin if it is possible somehhow to still cotrol those fnas

Hello. My problem is that I have a 3d printer that works on 24v and I would like to replace the fans with 12v. I have a larger capacity 12v power supply that i would like to install. My only problem is that the 3d printer cannot control these fans separately. I saw a video of how the negative cables are connected to the 12volt,24 volt power supply. The fans are connected to the positive cable of the 12v power supply and the other motors that require 24 volts are connected to the 24v power supply. I don't know what to do, what would be the best solution in this case?
