I have a BTT octopus pro and I want to make sure I know what I'm talking about before I try using 2 different power supplies at once. Is this the right idea? Right now I'm running everything on a single variable benchtop power supply that goes up to 18 volts, but both my heat break fan and part cooling fan are supposed to run on 24 volts, so I'm thinking I probably have a wall adapter somewhere that spits out 24V that I can use or something to that effect until I decide how I'm going to go abou…
