It can write with gel pens, permanent markers, and a variety of other writing implements to handle an endless number of applications. The Z axis is controlled by a servo motor to lift pen up and down.Ĭrazy Engineer’s Drawing Robot is a simple CNC Drawing Robot, capable of writing or drawing on almost any flat surface. It also uses a core Cartesian movement to control both X and Y axis. It uses Arduino UNO (Atmega328p) as the brain of the robot and a special GRBL firmware for G-Code Interpretation and motion control. It is open source and open hardware based project. The Crazy Engineer’s Drawing Robot or Arduino GRBL CoreXY Servo Drawbot is a CNC based drawing robot. I have given most details so that you will not feel any problem if you are new to making projects of this kind. The guide is quite long with both text and video. Below I am writing a step by step DIY guide to help you build your own CNC Drawing Robot. It took me a month to make this Project and I had fun building it. This Project was my engineering’s final year capstone project. Thank you for showing Interest in this project.
