Drag to rearrange

Add sense wire - This mounts to the bare metal on the stepper motor between the cooling duct and the motor. I used the extra wire from my thermistor harness to make this wire.

Strip off 4mm of insulation and crimp the ring terminal on a piece of 300mm wire

Put the ring terminal in between the fan duct and the stepper at the lower right t-nut on the front. We will sandwich it here using this bolt

Slip the heater, thermistor, sense pin, 24v cooling fan and 5v heatsink fan wires through the channel in the between the Hermes mounting points

Once through add a zip tie near the thermistor molex connector to the full bundle to help retain the wires and keep strain off the thermistor. Feed the wires the rest of the way into the channel.
