Your browser can’t talk to the device over USB. Web flashing needs the
Web Serial API — please use Chrome, Edge, or Opera on desktop
(not Firefox, Safari, or a phone).
Web Serial isn’t available — see the note above.You need to allow the serial port to continue.
Plug the board in via USB-C, click the button, pick the
USB-Serial CH343 port, and let it flash. ~30 seconds.
How it works
Connect the board to your computer with a USB-C data cable.
Click Connect & Install and choose the serial port that appears.
Confirm the install — the orb is fully erased and flashed with the latest firmware.
On first boot it opens a Wi-Fi setup hotspot printorb-setup-xxxx;
join it to configure your printer.
Stuck in the bootloader? Hold BOOT, tap RESET, release BOOT,
then retry. Already running PrintOrb? You can also update wirelessly at
printorb.local → Update tab.
