GND of hot end and fan both go to 12/24v when off (0 when on) so is not compatible with digital pin gnd's
Also since the hotend and fans the GND is switched, you cant join these either... as they would interfere with each other.

@MKSA
On most boards The -ve pin on the mosfets plugs are not actually GND's
if you measure voltage from the power supply gnd to a mosfet + pin is will always read +12v or +24v what ever your system is on (some board do generate 12v from 24v for fans)
if you measure voltage from the power supply gnd to a mosfet - pin it will read 12/24v when off (ie difference between + and - pins is 0v)
and will read 0v when on. (ie difference between + and - pin is 12 or 24v)
And yes this confuses most people trying to debug why their mosfets don't work.
technically the -ve pin floats, but 12/24v flows through the connected device (fan/heater etc) and you read 12/24v

Twisting, not braiding is recommended to reduce noise.

I have tested braiding as shown in the photograph and it is effective in reducing noise. it is also a method sometimes used in low level multi conductor signals cables e.g. ecg or multiple photodetectors.

You can always braid twisted pairs....
