CoreXY's (mostly) parallel kinematics mean that the motors, typically the largest source of inertia on a DIY-grade stage, are stationary. So reduces machine weight as you can now use lighter rods and mechanism on the X axis as now it doesnРІР‚в„ўt have to carry the heavy stepper motor.Р”Р‡ast: CoreXY believe in speed. CoreXY is a technique of motion control in 2D axis using a single continuous belt for both the axes.Р”Вesign Advantage: The Design of the Drawing Robot is Compact as the Y axis motor as well as X axis motor is also on the main chassis, which keeps the centre of gravity closer to the chassis. Miscellaneous Tools and Components CoreР”В¬ore makes things easy and have added advantage in my build.4 x Special Liquid ink PEN of multiple colour.3 x BLDC Fan (Not Necessary if you are not in tropical climate).

2 x Pololu Step Sticks A4988 Stepper Driver.

1 x Micro Servo SG90 (Later I Used a Bigger Servo for Quality).

10 x F623ZZ Bearings (I used Plastic Pulleys to reduce cost).

8 x SC8UU (Will suggest u to use SC10UU/SC12UU).

4 x 8mm smooth rods (I used 8mm, will Suggest you to use 10mm/12mm) 600mm Long.

2 x NEMA 17 Steppers 1.8 Degree Step 12v Torque more than 5kg/cm.

Not bad! CNC After Drawing Project Bill of Material AxiDraw costs 475$, Crazy EngineerРІР‚в„ўs Drawbot costs 150$.AxiDraw can write with a fountain pen, Crazy EngineerРІР‚в„ўs Drawbot not (yet).Crazy EngineerРІР‚в„ўs Drawbot is Made of Wood to reduce cost, while AxiDraw is in metal (? this is not very clear watching the pictures).Crazy EngineerРІР‚в„ўs Drawbot has a large working area (45Р“вЂ”38), like an ARCH B paper bigger than A3, while AxiDraw has a normal working area (30Р“вЂ”20), like an A4 paper.Crazy EngineerРІР‚в„ўs Drawbot is based on Arduino, while AxiDraw is based on the EBB Driver board.Crazy EngineerРІР‚в„ўs Drawbot is a Cartesian CoreXY movement (H-bot I think) similar to AxiDraw.Project Comparison with AxiDrawР”В¬razy EngineerРІР‚в„ўs Drawbot is similar as well as different from AxiDraw:

We predict too much for the next year and yet far too little for the next ten. The dreams of yesterday are the hopes of today and the reality of tomorrow. My Crazy Drawing Robot can handle paper as big as ARCH B. But they were mostly using A4 paper so I made one for myself with the largest work area of all above.

AxiDraw is very fascinating and quite a beautiful product.Р”В¬ollectively I studied all of these and found it cool.

If you Google DRAWBOT you will come across few interesting projects and product out of which : Finally, I thought to make a CNC Drawing Robot that required relatively only a fraction of the cost of the CNC Milling machine. 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. That time I came across a brand called Inventables that manufactures Desktop CNCs for Makers and low volume manufacturing. 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.

Signing diplomas and other certificates.

Its writing head extends beyond the machine, making it possible to draw on objects bigger than the machine itself. 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.Р”В¬razy EngineerРІР‚в„ўs 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 EngineerРІР‚в„ўs 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 engineeringРІР‚в„ўs final year capstone project. Thank you for showing Interest in this project.
