Building a J-head Hotend
- pre-assembled j-head hotend
- heating element 40W with cables
- hotend clamp
- isolation for the thermistor
- 2 small ferrules
Adding the heating element
Adding the thermistor
First prepare the cable you gonna use for the thermistor, and strip about 1cm of isolation from it. It should look like this:
Then add the ferrules to the cables, cut the thin isolation into half and add it to the thermistor:
Then carefully wind the thermistor cable around your striped wire to make good contact:
Finally move the ferrule over the wire connection and crimp it together using pliers. Do this for both thermistor cables. If you like, you can also add some isolation tape to make sure it doesnt make any shorts. The finished thermistor should look like this:
If you have a soldering iron ready, you can also solder the wires to the thermistor if you like.
Now you j-head hotend is ready. You can either push on the hotend clamp onto the top and mount the hotend between you carriage and nearly any extruder, or if your extruder supports this, you can push it directly into the extruder body and fix it with screws.
