Spark

🚧 Under Construction 🚧

Spark is an OSS/OSH desktop EDM tech stack. It'll bring the ease of 3D printing to fine metal parts.

Maybe. Someday.

This repo is mostly about software & machine CAD.

To construct a Spark machine, you need these too:

• https://github.com/xy-kasumi/Spark-corefw
  • Zephyr-based firmware for main board (currently only supports BTT Octopus Pro)
• https://github.com/xy-kasumi/Spark-pulser
  • EDM board (PCB design & firmware)

Directories

Directories are roughly divided into two groups.

Build & Use

• docs: contains assembly manuals and specs
• dicer: web page that generates G-code from STL for the machine
• shell-dashboard: web page to control the machine
• shell-spooler: Go program that acts as interface between shell-dashboard & physical board
• mech: CAD files for the machine

These are necessary for building, testing, and using the machine.

Development & Operations

• sim-machine:
  • purpose: visually validate G-code, iterate on machine kinematics
• sim-wear: particle-based tool vs work simulation
  • purpose: validate & iterate on "sweep" patterns without physical experiments
• brand: contains project's visual identity such as logo

These are useful resources to further the development of the machine and/or the Spark project.

Simulations should be independent of each other. They should actually add net value to the project. Typically they do so by allowing quicker iteration.

dicer can send G-code directly to sim-machine (if they're served from the same origin), by using Broadcast Channel API.

Tips

Note: "localhost" and "127.0.0.1" are considered different origins.

When ./build.sh or ./watch.sh cause directory listing page to show up:

• Configure liveServer.settings.wait to be larger than build time. e.g. 1500 (ms)

When log output from spooler is causing refresh:

• Add "**/logs/**" to liveServer.settings.ignoreFiles.
