Deneb, a local-first firmware detour for the UltiMaker 2+ Connect
An independent community firmware project that adds a rebuilt touchscreen interface, local-network printing, and a trusted-LAN Web UI to the UltiMaker 2+ Connect.
- For
- UltiMaker 2+ Connect owners who want local control
- Worth noticing
- Network setup uses wifi.txt or eth.txt on a FAT32 USB stick instead of the stock captive portal.
Field notes
The project rebuilds the printer’s LVGL touchscreen rather than merely adding a browser dashboard, with swipe scrolling and draggable sliders replacing tap-only stock controls. Its local-network workflow combines Cura discovery, USB jobs, and a trusted-LAN Web UI behind one native print backend. Setup documentation covers both Wi-Fi and Ethernet, including FAT32 USB files named wifi.txt or eth.txt. The project is experimental, independently maintained, and licensed under MPL-2.0.
