CNC Pen Plotter from Scratch: Arduino Uno + Dual NEMA17 Stepper Motion System

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

You'll command two NEMA17 stepper motors to move a pen in precise X-Y paths, turning vector art or hand-drawn sketches into plotted drawings. A servo lifts the pen between strokes, just like a full-fledged CNC machine. This kit gives you the exact electronics and wiring needed to build your own working plotter, perfect for learning motion control and G-code generation.

What You'll Build

A functional pen plotter that reads G-code and traces designs on paper. Use it to draw circuit layouts, create hand-lettered art, produce custom greeting cards, or prototype CNC routines before scaling up to a laser cutter. With an open-source toolchain - GRBL firmware, Universal Gcode Sender, and Inkscape - your drawings move from screen to paper with repeatable accuracy.

What You'll Learn

• How to configure and control two NEMA17 stepper motors using A4988 drivers and a CNC Shield V3
• Generating and sending G-code to an Arduino-based motion controller from a computer
• Calibrating a belt-driven XY stage to achieve consistent line accuracy
• Integrating an SG90 servo as a pen lifter to handle multi-stroke and multi-colour plotting

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for B.Tech ECE/EEE students building a mechatronics or embedded systems project, CBSE Class 11-12 students exploring automation and robotics, and ATL tinkering lab mentors guiding intermediate-level hardware builds. Makers preparing for Smart India Hackathon hardware tracks or anyone who wants to go from blinking LEDs to real CNC motion will find this kit a structured launching point.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
