A round desk dashboard for Bambu Lab printers. It connects to each printer's own MQTT broker on your LAN, so the printers can stay on Bambu Cloud and the monitor keeps working when the cloud doesn't. It shows a two-printer overview, progress with "done at" times, temperatures (both nozzles on the X2D), AMS and AMS HT spools in their real colours and HMS codes. Prints that finish, pause or fail trigger a full-screen alert with sound.
Every part of the board is used: the knob and its push switch drive pages and menus, touch handles swipes, the speaker plays alerts, and optional Qwiic sensors add room climate and auto-brightness. Both panel revisions are detected at boot. It installs from a browser flasher and updates over Wi-Fi.
I wrote up the build, including the LVGL crash I caught with a PC stress test, in I Turned a $32 Knob Into a Bambu Lab Print Monitor.
