Steps to clean and reassemble the Tevo Tornado stock hotend

Step 1: Take everything apart and clean it, you have to be able to look through the throat and the nozzle without obstacles.

Step 2: Remove the PTFE Tube from the pressure fitting and inspect the tube for damages/compressions and cut off the damaged part.

Step 3: Put everything together nice and tight and mount it on the axis without the fans and do not insert the PTFE tube.

Step 4: Heat up the nozzle to 230°C and when heated carefully retighten the nozzle, let it cool down after that.

Step 5: Insert the PTFE tube and push it all the way in until it doesn’t move anymore.

Step 6: Install the fans, level the bed and try printing.

Upgrades i made to my Tevo Tornado

The Tevo Tornado is in my opinion a quite good printer out of the box, however there are some things that can be upgraded very easy that help raise quality reliability and safety.

  1. Level Knobs

    The leveling nuts on the Tornado are small and it is difficult to level the bed, this makes it easier.

  2. Heat bed cables strain relief

    The power cables of the heat bed are connected to mains voltage this helps protecting the cables from movement stress. Later i replaced this with the ultrabase mount.

  3. Ultrabase mount

    The “Build Tac” sheet from Tevo is quite good but is damaged quickly when trying to remove parts that stick very well, for that i decided to replace it with a 310x310mm anycubic ultrabase and used these mounting brackets.

  4. Wire guide

    For the horizontal profile to guide the cables going to the hotend.

  5. Z-Axis fine adjustment

    Helps to fine adjust Z height very easy.

    Link to the thing will follow.

  9.  Self centering Z coupler

    The coupler installed on the Tornado is not the best and can cause wobbling. I replaced it with this design.
