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.

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.

PERFORMANCE COMPARISON TEST
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.

KNOMI 2 STARTUP
Power KNOMI 2 via the USB-C or ZH1.25 connector. On power up, KNOMI 2 will display the HELLO
interface indicating readiness for network configuration.
This interface appears in three cases: first boot, after factory reset, or if unable to connect to the
previously set Wi-Fi within 15 seconds of boot.
If KNOMI 2 is already installed in the StealthBurner but you need to switch
Wi-Fi networks, you can also press the BOOT button using a thin tool like a
hex key.
CONFIGURING WI-FI
WWW.BIGTREE-TECH.COM
Before initial setup and powering on, ensure the external antenna is connected.
After successful configuration, the antenna can be removed for installing in the
StealthBurner. Note that the antenna will need to be reattached per this manual's
instructions after final assembly.
