Duet3D DuetScreen is a family of colour touchscreen controllers for machines based on Duet 2 and Duet 3. It is also compatible with other controllers running RepRapFirmware. The current hardware implementation is the DuetScreen 7; other screen sizes are planned in the future. The DuetScreen application is developed on LVGL and offers a modern user interface for machine control, initially focused on 3D printers. Its modular design allows the development of future versions for other machine types.
