Make a CNC Drawing Machine

Design, build, and program a machine that draws a pattern, performs the task accurately, and repeats the task.

Think about these questions:

• What is the best way to attach a pencil or marker?
• Which type of motorized mechanism can move the pencil or marker in two dimensions?
• What design features will ensure the machine’s movements are accurate and repeatable?

Hints
Use typed notes, a handwritten lab notebook, sketches, photos, screenshots, or videos to document your design process. Make sure you explain:

1. Any challenges you are facing.
2. How you are working to overcome these challenges.
3. What resources you need.
4. Ways in which your classmates or teacher can help.
5. Any early signs of success you are observing.

Communicate the results of your work by:

• Creating a video that demonstrates your design process starting with your initial ideas and ending with your completed project
• Creating a presentation that connects your projects with real-world applications of similar systems

Ask for feedback and conduct a self assessment. Use the evaluation tools your teacher has provided.
