CNC Plotter Kit with Arduino Uno & NEMA Stepper Motors
Build a High-Precision CNC Plotter with Arduino Uno & NEMA17 Stepper Motors
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your Arduino Uno into a precise 2-axis plotter that reads G-code commands over serial and draws complex vector patterns on paper. This kit equips you with two NEMA17 steppers, an SG90 servo pen lifter, and a CNC Shield V3 to build a desktop pen plotter from scratch-whether for engineering prototypes, PCB art, or custom signage.
What You'll Build
A fully functional CNC pen plotter that takes standard G-code (like those used by laser cutters or 3D printers) and draws with ballpoint or felt-tip pens on A4 paper. You'll create a machine capable of intricate line art, circuit schematics, and even handwritten text, all driven by open-source GRBL firmware running on the Arduino.
What You'll Learn
- Fine-tune A4988 stepper drivers for precise microstepping and current control.
- Parse standard G-code (G0, G1, G2, G3) to convert toolpaths into motor steps.
- Implement servo-controlled pen lift with accurate Z-axis timing.
- Debug motion artifacts and ensure repeatability with homing routines.

Who This Kit Is For
Tailored for engineering undergraduates (B.Tech in ECE, EEE, or Mechanical) tackling precision motion projects, as well as Smart India Hackathon teams prototyping pen plotters for automated documentation. Also ideal for ATL Tinkering Lab students (Class 11-12) ready to move from Arduino basics to CNC-level machinery, and hobbyists seeking a reliable G-code drawing setup without hours of part sourcing.
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.
What if I get stuck during the build?
Our AI companion, trained on this exact CNC plotter project, provides step-by-step debugging for stepper calibration, belt tensioning, and G-code issues. You can also WhatsApp us for human support.
Can I use this plotter to draw on different sizes or materials?
The 400mm linear rails allow a drawing area up to roughly A4 (210 x 297 mm). By adjusting the pen holder, you can use pens, pencils, or even a light laser module (sold separately) for engraving with appropriate safety precautions.
Does the kit include the GRBL firmware, and is it pre-configured?
The Arduino Uno is not pre-flashed, but the AI companion will guide you through uploading GRBL v1.1 and configuring key parameters like steps/mm for your GT2 belts. This ensures you understand the logic behind the machine's motion.
What if a stepper driver fails or my servo is faulty?
Our 7-day defect replacement policy covers any manufacturing faults. Reach out via WhatsApp with a short video of the issue, and we'll ship a replacement component immediately from Bengaluru.
Two NEMA17 steppers drive XY axes and a servo lifts the pen. Draws G-code paths from serial input.
