PERFORMANCE COMPARISON TEST¶
DOES USING KNOMI 2 IMPACT YOUR STEALTHBURNER'S PERFORMANCE?
We have customized installation print parts for KNOMI 2, facilitating its easy installation into your Voron StealthBurner. In particular, our StealthBurner Main Body not only retains the original fan positions but also incorporates a circular ventilation opening at the top, enhancing compatibility and optimizing heat dissipation.

MOUNTING PLATE
Before you start the assembly, we recommend preparing these two printed parts in advance. The Mounting Plate is designed with a snap-on feature due to size limitations and considerations for the air duct design. This may cause some wear and tear through repeated disassembling and reassembling. Hence, we suggest printing several extra copies of this part for future use.
We conducted a comparative analysis measuring wind speed and acoustic energy levels between the original StealthBurner and our customized version featuring vents and KNOMI 2 add-on. The results showed that both versions performed similarly, indicating that adding KNOMI 2 will not compromise the performance of the StealthBurner.
PACKING LIST¶
OVERVIEW¶
CONFIGURING WIFI¶
ROUTER ENCRYPTION MODE
Due to device compatibility issues, KNOMI 2 cannot configure networks with WPA PSK encryption mode. If you're having trouble getting your network to configure successfully with KNOMI 2, please check the encryption mode of your router. You may need to switch your router's encryption to a mode like WPA/WPA2 PSK mixed mode, or another mode.
CONNECTION LOST
This status on KNOMI 2 indicates it has lost connection to the WiFi hotspot. Potential causes:
- You changed the WiFi name or password, requiring a long press of the BOOT button to get to the HELLO interface and reconfigure KNOMI 2's network connection.
- KNOMI 2 is too far from the WiFi hotspot, resulting in poor signal quality.
INSTALL KNOMI TO STEALTHBURNER¶
POWER CABLE ROUTING
As shown, guide KNOMI 2's power cable through the hole in the printed part, and then direct it towards the rear of the EBB SB0000 CAN.
Power Supply
If you are not using the EBB SB0000 CAN or a similar tool board, after routing the power cable as shown in the diagram, connect it to your motherboard or other power source.

KNOMI 2 supports full-screen touch, swiping up, down, left, and right, as well as long press operations.
Main Interface
HOW TO EXTRUDE AND RETRACT FILAMENT？
Swipe right from the Standby UI to access the Extruding/Retracting Filament interface.
HOW TO ADJUST THE TEMPERATURE OF THE NOZZLE/BED?
Swipe left from the Standby UI to access the Nozzle/Heated Bed Temperature Settings interface.
MANUAL TEMPERATURE ADJUSTMENT IS NOT REQUIRED
1、Advanced setting - please only use it if you fully understand its specific function.
2、KNOMI has built-in mDNS. You can enter "http://knomi.local" in the browser (The default hostname is KNOMI. If users have modified it, please use the custom name instead of “knomi” in the URL, the URL characters are case-insensitive), or view the IP address on the "Knomi Info".
HOW TO ADJUST KNOMI UI COLORS?
You can further customize the saturation and brightness: After selecting a color on the wheel, long press the black area outside the wheel to cycle through saturation, brightness, and back to the RGB wheel.
When you pick a saturation/brightness level, returning to the RGB wheel will show that saturation/brightness.
