You'll need to swap or replace your hot end on the Series 1 or Series 1 Pro in situations where the hot end has either reached the end of its service life or if you are switching between it and another hot end with different specifications.
- 3mm Allen Wrench
- New Hot End
Start by bringing the bed to home position, then turn off your machine. If you were just printing or heating the extruder, please allow time for the hot end to cool. (Fig. 2)
Once the hot end has cooled and is ready to be removed, take the 3mm Allen wrench supplied with the printer and remove the single bolt in the middle of the extruder. (Fig. 2)Set aside your front extruder block on the print bed. (Fig. 3)
Next, remove the hot end plug from the printed circuit board on the side of the toolhead. Once removed, the hot end should be set aside or thrown away if broken. (Figs. 4, 5)
Note in Fig. 4 the clip connecting the blue and salmon colored wires. Squeeze and pull on the clip to disconnect the wires.
Start by pushing on the connector to the hot end. Next, you may want to add more thermal paste into the channel of the extruder block if there is not much left. (Fig. 6)
After installing the hot end connector put the front block on making sure that the gap around the block is closed. (Fig. 7) Tighten the 3mm allen bolt on the front of the extruder, securing the two halves together to clamp the hot end in place. (Fig. 8)
Now you should be ready to get back to printing!
