Kiri:Moto CAM & Workflow

Kiri:Moto is a free, browser-based CAM (Computer-Aided Manufacturing) and toolpath generator designed for desktop CNC machines. It works with 2D, 2.5D, and 3D operations, making it a perfect companion for your Ender 3 CNC build.

Why Kiri:Moto?

  • Browser-based – no heavy installation required.
  • Supports milling, carving, and drawing operations.
  • Compatible with GRBL, Marlin, and Klipper.
  • Familiar interface for makers already comfortable with 3D printing.

Getting Started

  1. Open Kiri:Moto in a modern browser.
  2. Load your 3D model (.STL, .OBJ, .SVG for 2D operations).
  3. Set your machine parameters:
  4. CNC type: “Cartesian”
  5. Bed size: Match your Ender 3 build
  6. Tool diameter: Match your spindle or endmill
  7. Configure the workspace and stock:
  8. Define material dimensions
  9. Set origin (bottom-left or center of stock)
  10. Choose your operation:
  11. 2D pockets, traces, or cuts
  12. 3D carving
  13. 3D adaptive clearing for larger parts

Workflow Tips

  • Link stock and model – Ensure the model is positioned relative to the material to avoid collisions.
  • Work Coordinate System (WCS) – Use the coordinate system to define origin and orientation for each part.
  • Output – Select your post-processor:
  • Klipper (.gcode)
  • GRBL (.nc)
  • Marlin (.gcode)
  • Simulate – Always check the toolpath simulation before milling.

Integration with Ender3CNC

  • Kiri:Moto output works directly with Klipper and GRBL-based workflows.
  • Toolpaths generated in Kiri:Moto can be sent to your Raspberry Pi or Ubuntu laptop running your CNC controller.
  • Supports dual Y-axis operations, ensuring synchronized movement across your upgraded Ender 3 CNC.

Tip

For complex parts, break your workflow into multiple operations: * Roughing pass → Finishing pass → Engraving or drilling * This reduces load on your motors and improves surface finish.
