deepnest

A fast nesting tool for laser cutters and other CNC tools

deepnest is a desktop application originally based on SVGNest

• New nesting engine with speed critical code written in C
• Merges common lines for laser cuts
• Support for DXF files (via conversion)
• New path approximation feature for highly complex parts

This Fork

The primary goal has been to get deepnest buildable again, which has been achieved. Now I'm going to fix the bugs, that are reported origin to deepnest-io/Deepnest and other forks.

Prerequisites

• Node 20+: Node.js. You can use the Node Version Manager (nvm):
  • nvm-windows to download Node and change versions.
• Python 3.7.9 and up You can use the Python Version Manager (pyenv):
  • pyenv-win to download and change versions.
• Visual Studio with Desktop Development with C++ extension
  • Install VS2022 from https://visualstudio.microsoft.com/vs/features/cplusplus/
  • or, as an administrator via npm install --global windows-build-tools (older VS version)

For ubuntu (or when you're not sure how to build) look at the build workflow:

https://github.com/deepnest-next/deepnest/blob/main/.github/workflows/build.yml#L28

Possible Problems

• On Windows 10 1905 or newer, you might need to disable the built-in Python launcher via
  • Start > "Manage App Execution Aliases" and turning off the "App Installer" aliases for Python"
• close-and-open all command shells and your IDE to activate the latest setup

Building

git clone https://github.com/deepnest-next/deepnest
cd deepnest
npm install
npm run build
npm run start

Rebuild

# If you change the electron-related files (web files, javascript), a build with
npm run build

# If you change the the Minkowski files (the `.cc` or `.h` files):
npm run build-all

Running

• npm run start

Clean builds

npm run clean  && npm run build

# full clean, incl. `node_modules`
npm run clean-all && npm install && npm run build

Create a Distribution

npm run dist

# During development, you can combine `clean-all, build-all and dist` via:
npm run dist-all

The resulting files will be located in .\deepnest-<version>-win32-x64.

Create a zip file of this folder for a simple distribution.

Debugging

If the environment variable "deepnest_debug" has a value of "1", deepnest will open the browser dev tools (debugger/inspector).
