    heater cartridge

    I have a creality ender 3 pro and recently did a mainboard update from the old v 1.4.4 to the new v 4.2.7. Everything went well, but I have now read somewhere that you should also look at the plus and minus connections of the heater cartridge, but how do you do that? The two cables on that cartridge are both red.Now my question here is whether it really makes a difference how you connect this.

    I don't believe so, it is a heating element, just a resistance load, so make no difference which way the current flows.
