I have some questions about some wiring options. I am completly redoing the wiring on my printer and i have created a custom board where my whole x carriage will connect to. At the moment this includes two fans, x-end stop, heater block, and thermistor. This would require 10 different wires to accomplish but from my continuity tests on the board itself it seems that the positive sides of the fans and the heater block are all connected with their ground being triggered by the mosfet. my question is can i eliminate two wires and run a single positive cable to my board for all three devices and cut my wiring down to 8 or will that cause issues?
