anyone reduce wires to extruder by combing power/GND cables?
-
Like many, have a bundle of wires running to my extruder which combine into what looks like quite a lot of mass. From memory:
40W heater: 2 wires +24v PWM / GND;
Parts fan: 2 wires 24v PWM / GND;
Cartridge thermistor: 2 wires +5v stimulus / sense;
Hotend fan 2 wires: 24v PWM / GND;
BLT touch: 3 wires - +5v / GND / sense;
Endstop microswitch ?+5v / sense;(and 2 pairs of wires to a direct drive stepper motor!)
Is there a way we can reduce this by:
a) combining the GND connections of several elements into a single wire? (Depending if PWM is at the source or the drain....)
b) is one of the thermistor cables +5v such that it could be shared with the BLT?
Anyone done anything like this?

Excellent, thanks!
So:
+24v to Heater, Parts Fan and Hotend fan;
GND to BLT and Endstop;total saving: 3 wires!
