Product information & technical details


With the Bigtreetech KNOMI you always stay well informed about the current status and the individual steps of your 3D printer! The round touch mini screen is an open-source product specially designed for Klipper 3D printers.

Control via touch

With the intuitive touch controls you can operate your Voron StealthBurner directly on the screen. The following functions can be controlled via touch:

  • The extrusion and unloading of filaments
  • Selecting the model and starting printing
  • Setting the temperature for the nozzle or heated bed
  • ABL/QGL/Homing

User-friendly UI

With KNOMI you get all the data presented at a glance. Enjoy the printing progress with meaningful and visual feedback:

Standby: When idle, KNOMI's gaze moves left and right. The Voron logo appears every 10 seconds.

Heated Bed – Warming Up: While the desired temperature is displayed at the top, the history of the temperature change appears at the bottom.

Nozzle – Warming up: The desired temperature is displayed at the top and the course of the temperature change at the bottom.

Leveling: The printer is currently levelling itself (Homing, ABL, QGL).

Ready to print: The print bed and nozzle have reached the target temperature and the printer is ready for printing.

Start Printing: The print head moves.

Printing Progress: The progress displayed in percent, a circular bar and bars on the X, Y and Z axes visually display the printing progress.

Print Completed: The printing process is completed.

The KNOMI user interface can be customised in colour (with an incredible 16.8M colours) to suit your wishes and preferences.

Print parts yourself for the Voron Stealthburner

You can easily install KNOMI into your Voron StealthBurner using the assembly print part files provided by Bigtreetech. Download this here. Before you begin the installation, you should have the printed parts handy.

The fan retains its original position in the specially developed StealthBurner housing, which has been equipped with additional ventilation openings on the top for better heat dissipation. This means that KNOMI has no impact on the performance of the StealthBurner!

Note that the EBB SB2240/2209 CAN can be purchased separately!

Video angle for the optimal view

KNOMI features a 178° wide-angle screen that provides a clear view from any perspective. This means you can easily monitor individual steps in your 3D printing processes at any time.

Flexible connectivity

KNOMI comes with an external WiFi antenna that easily communicates with a 3D printer via a WiFi connection. The mini device also supports OTA firmware updates.

Thanks to expandable IoT functions, external modules such as cameras (OV2640), button modules, temperature and humidity sensors (BME280) and wireless charging modules can be connected for greater flexibility.

Open source and adaptable

KNOMI is open source and can be adapted to your 3D printer without much effort. Its user interface can also be personalised according to your wishes.
