CNC canvas painting system

There are two goals of IfThenPaint v2 project:
1. create canvas paintings that I would be proud to display in my own home
2. enjoy the technical journey to get there

I have been fascinated by the technical challenges of CNC painting for nearly a decade. This project is my latest design.

What makes this system unique?

  • Thick paints. Paints straight from the tube. No thinning necessary. 
  • Paint mixing. Paints can be dispensed and mixed anywhere in the workspace. Palette optional.
  • Automated tool change. The machine automatically configures itself for paint dispensing and tool manipulation operations. No user interaction required.
  • Canvas size. Up to 18x24in. 

What is novel about this system?

  • A custom "painterly" bitmap to paint stroke algorithm.
  • A custom hobby-level two-stage tool change solution. The first stage tool change is a hacked heavy-duty tripod mount and magnetic electrical contact. The second stage of the tool manipulator head uses a quarter turn bicycle mount. The second stage of the paint dispenser head is a laser cut magnetic plate design.
  • Custom CNC painting software under development.

  • Operational Testing

    Recommend watching at 2X speed or faster. 

    This video demonstrates some of the initial operational tests. It is a result of extensive testing of each operation. Some minor mechanical issues, but overall nothing that can't be fixed with small tweaks.
