A cross-platform 3D printer control app built with Flutter. Connects to printers via serial (USB) with a real-time terminal, temperature monitoring, movement controls, and macro system.
At this moment only build for macos in releases but if you have flutter installed you can compile your platform version.
- Serial connection — connect to printers over USB with configurable baud rates and auto-reconnect
- Real-time terminal — send G-code, view responses, filter system commands (M105/M114), comment syntax highlighting, persistent command history with up/down navigation
- Temperature monitoring — live nozzle and bed readouts with target controls, separate nozzle/bed sparkline charts over selectable time windows (30s / 1m / 5m / 15m)
- Movement controls — XY radial D-pad with adjustable step sizes, Z-axis panel, home buttons (All / X / Y / Z), coordinate display
- Extrusion — feed rate and amount sliders with E‑/E+ buttons
- Speed & Flow — live speed and flow rate override sliders
- Macros — collapsible panel with custom G-code macros (add, edit, delete, execute)
- Multiple printers — save and switch between printer configurations
- Theming — Tokyo Night (dark) and Tokyo Night Day (light), auto system theme
- Responsive UI — bottom navigation on mobile, vertical navigation rail on desktop (≥600px) with multi-column layouts
