INTRODUCTION to Arduino Drawing Machine v1
The Crazy Engineer’s Arduino Drawing Machine or Arduino GRBL CoreXY Servo Drawbot is a CNC based drawing robot. It is open source and open hardware based project. It uses Arduino UNO (Atmega328p) as the brain of the robot and a special GRBL firmware for G-Code Interpretation and motion control. It also uses a core [X, Y] Cartesian movement to control both the X and Y axis. The Z axis is controlled by a servo motor to lift pen up and down.
Crazy Engineer’s Drawing Robot is a simple CNC Drawing Robot, capable of writing or drawing on almost any flat surface. It can write with gel pens, permanent markers, and a variety of other writing implements to handle an endless number of applications. Its writing head extends beyond the machine, making it possible to draw on objects bigger than the machine itself.
Suggested applications include:
• Decoration Drawing
• Computer artwork
• Technical drawing
• Notes and cards
• Writing signatures
• Signing diplomas and other certificates
• “Hand-written” lists

When I was in my 2nd year of my engineering I did some research and came across the term CNC and I got fascinated by that. That time I came across a brand called Inventables that manufactures Desktop CNCs for Makers and low volume manufacturing. My early research was on CNC milling and drilling but making a CNC milling or drilling machine requires good investment and that is what I was lacking. Finally, I thought to make a CNC Drawing Robot that required relatively only a fraction of the cost of the CNC Milling machine.
If you Google DRAWBOT you will come across few interesting projects and product out of which :
Collectively I studied all of these and found it cool. But they were mostly using A4 paper so I made one for myself with the largest work area of all above. My Crazy Drawing Robot can handle paper as big as ARCH B.
