Alumina Interface

Alumina is an integrated CAD/CAM, physics simulation, and motion control solution written entirely in Rust. It is intended to control laser and plasma cutters, 3D printers, CNC routers and mills, and lathes.

Alumina Firmware and Interface get linked together at compile time and fit in the onboard flash of a single microcontroller, reducing design complexity, part count, and cost.

• Alumina Firmware
  • targets the xtensa and risc-v esp32 microcontrollers
  • sets up a Wifi AP called "Alumina"
  • serves the Alumina UI via HTTP
  • responds to commands from the Alumina UI via HTTP
  • performs motion planning and step generation
  • (planned) port to embassy and FoA and smol
  • (planned) port to other embassy hardware targets
• Alumina Interface
  • targets WebAssembly
  • draws geometry using WebGL and egui
  • works in any browser, desktop or mobile
  • CAD using csgrs and egui_node_graph2
  • calculate and display 2D slices of 3D models
  • Communicates with Alumina Firmware to display diagnostic log, graph, and photo of the controller
  • Fits in < 4Mb microcontroller flash, including firmware
  • (planned) multiple controllers in sync
  • (planned) use wgmath to move most CAD and geometry and toolpath calculation to the GPU

Todo

• implement picking for lines and vertices and faces
• single-click for individuals and click-drag for multiples.
• https://github.com/JeroenGar/jagua-rs and/or https://github.com/JeroenGar/sparrow for bin packing
• generate toolpaths from slices
• send toolpaths to firmware
• echo sent / received commands in Diagnostics console
• finish SD card support
• enable persistence via https://docs.rs/eframe/latest/eframe/
• implement tweening for snap view
• ensure font picker in truetype text node works / gets pre-populated
• ensure pin logging works for OUTPUT and INPUT modes and reports apropriately per-pin
• add command stream to architecture graphic
• switch to shift-scroll for zoom, so two-finger scroll can be used for pan in X and Y for mobile
• figure out improper rendering in Chrome Android Pixel 6a
• get UI building for native so that "cargo bloat" can be used
• get long-click as right-click working for Design tab Central view, or add button for opening node menu on mobile
• convert Diagnostics and Design tabs to collapsible tool panels
• implement settings dialog
  • automatically re-render on graph change checkbox
  • wifi information
  • IP information
  • URI setting
  • Enable / Disable SD checkbox
    • Enable / Disable logging to SD checkbox (greyed out when SD is disabled)
• implement about dialog
  • device image
  • pin configuration information
  • build date
  • build stats
  • feature flags
  • github links
  • github sponsor link
  • Licenses notices
