An Electron app for creating radially symmetric patterns.

And then generates G-Code to carve the pattern on a CNC machine with a V groove bit.

Requires Node.js.

In top-level directory do npm install to download all of the required modules.

Do npm test to run the unittests.

• The Reflection checkbox controls whether two mirrored copies of the curves should be included.
• The Grid checkbox controls whether a grid should be displayed.
• The Clear button deletes all of the curves.

The final group of input controls are used to generate G-Code.

• The Φ field is used to set the maximum diameter of the V bit in mm.
• The ∠ field is used to set the angle of the V bit.
• The next field is the name of the generated G-Code file.
• The Generate GCode button will write the current scene to the file.
