steps 1-2

Step1:

The Bowden tube coupler screws directly into the top of the heatsink.

Step2:

Screw the coupler into the heatsink, then push the tubing into and through the couple until it stops

steps 3-4

Step3:

Insulate the thermistor legs with kapton tape up to the base of the glass bead. All bare wire should be covered

Step4:

Thermistor goes into the small hole the side of the heater block

(it is secured by kapton tape)

steps 5-6

Step5:

Place the heater cartridge into the smooth hole on the heater block; a small amount should be poking out each end. The M3 grub screw secures it.

Step6:

Screw the heatsink onto the long end of the heat break.

steps 7-8

Step7:

Place the heatsink into the printed fan mount. Screw down and secure the fan to the printed fan mount.

Step8:

Final step- using software heat the now complete hot end up to 290C, then once up to temperature you need to do a final tightening of the nozzle against the heat break to form a good seal. This prevents any plastic leaking.
