GeoSlicer-GCode Exporter 🛠️

📌 Overview

GeoSlicer-GCode Exporter is a Blender addon that allows you to export geometry node toolpaths as G-code for CNC machines, 3D printers, laser cutters, and pen plotters.

🚀 Features

• Topology Slicer (View3D > Sidebar > GeoSlicer > Slicer):
  • Slicing strategies: Planar, Geodesic (equal surface distance), Vase (topological, between boundary loops), Weight (paint your own slicing field, Tissue-style).
  • Layer modes: fixed Count or Height (count derived from max layer height).
  • Toolpath-aware output: seam alignment, ping-pong direction for open curves, uniform resampling, CCW loops ordered bottom-to-top.
  • Slices the evaluated mesh (modifiers applied). Numpy-vectorized; uses scipy if installed.
  • Outputs <object>_curves for preview/editing, and Make Toolpath Mesh converts to <object>_toolpath — an ordered point mesh with draw/path attributes ready for the G-code exporter.
• Export Blender geometry node paths to G-code (.nc files).
• Supports multiple machine modes:
  • 🛠 CNC Mode
  • 🖨 3D Printing Mode
  • ✍ Drawing Mode
  • 🔥 Laser Cutting Mode
• Customizable feed rates, extrusion values, power settings.
• Supports custom start/end G-code.
