Performance Comparison Test¶
Question
Does KNOMI 2 affect StealthBurner performance?
Our custom-designed StealthBurner Main Body integrates KNOMI 2 seamlessly while maintaining optimal airflow and heat dissipation. The modified design includes a top ventilation opening, ensuring no compromise in cooling efficiency.

Mounting Plate¶
Before beginning installation, make sure you have both printed parts ready. Due to size constraints and airflow requirements, the mounting plate uses a snap-fit design. Note that this design may wear out with repeated removal and reinstallation. We recommend printing extra copies for convenience.
Our performance testing compared airflow velocity and acoustic levels between the standard StealthBurner and the modified KNOMI-equipped version. The results demonstrated equivalent cooling performance and noise output between both configurations, confirming that the KNOMI integration - including its additional ventilation features - maintains the StealthBurner's original operational performance without compromise.

Overview¶
CONFIGURING WIFI¶
Wi-Fi Compatibility
Due to device compatibility issues, KNOMI 2 cannot configure networks with WPA PSK encryption.If you experience connection issues during setup, please verify your router's encryption settings in the admin panel and change it to WPA/WPA2 PSK mixed mode or another supported encryption protocol to establish a successful connection.
Knomi Disconnected¶
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.
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.
