What you will get with this upgrade?

NEW FILAMENT SENSOR

The previous sensor didn’t work well with some specific filaments. The new sensor is using the optical sensor which is triggered by a simple mechanical lever. This sensor doesn’t care about the optical properties of the filament (it can be completely invisible) and cannot die because of mechanical wear.

EASIER SERVICE

Thanks to completely reworked extruder you don’t have to take apart the whole extruder if you want to change the nozzle or PTFE tube. As a bonus, the nozzle and the extruder motor is much closer to the X axis, this means less resonance and better prints too. Better Y axis belt tensioning is just the icing on the cake.

BETTER COOLING

Thanks to the better design of the whole extruder, air flow is increased and as a result, cooling capabilities are improved. We have also focused on cooling of the the printed object and MK2.5S/MK3S is better for printing from flexible materials.

This package includes:

  • IR filament sensor + cable
  • PTFE tube
  • Fan-shroud-black
  • Bolts & fasteners
  • Textile sleeve
  • 300g Black PETG for self-printed parts

Fantastic.

This hardwar + firmware package is a substantial leap forward that has solved some of my persistent problems with my Mk3. The design is much more elegant; particularly the fan shroud and heat exchanger cooling. The new filament sensor and auto loading capability is superb. The single screw adjustment of the bonden feeding gears is a blessing. All in all, I highly recommend this upgrade for all Mk3 users.

    Recommend upgrading

    This is a solid (and cheap) upgrade. I really wanted the filament detection to work on the MK3, and now the the upgraded extruder and the accompanying firmware update I am printing with reckless abandon. Will the printer run out of filament while I sleep? It doesn't matter! Now the printer parks and waits patiently for me to return and start the next reel. Super happy with the functionality.

    Extruder Upgrade Adventure

    With the kit installed and the firmware updated, it's like having a new printer again. Plus I really love the new autoload sequence.

    This upgrade is pretty serious, it took me about 3 hrs, but the instructions are good, like you would expect.
    There were a few issues that I documented in this video: https://youtu.be/3liw5eaWm1c hopefully you won't make the same mistakes I did. Especially correctly positioning that little connector for the sensor on the board.
