How to Make Polar CNC Drawing Machine

Introduction: How to Make Polar CNC Drawing Machine

About: Electrical engineer by profession

Hello friends welcome back in this new instructbales

Here I have made a simple Polar CNC drawing machine, I kept is as simple as possible complete structure is made out of wood.

I avoid to use 3D printer to keep it simple, so anyone can made it. So basically you think what is polar CNC means, so I will tell polar CNC's are quit different in comparison of traditional CNC,

Polar CNC are work in 360 degree format while traditional CNC are work in Cartesian coordinate system like X, Y & Z axis. In this this machine the Y axis (turn table) is polar format,

I have used a Custom made PCB to give professional look to my project, I ordered my PCB from JLCPB.COM they have very affordable rates for PCB like 2$ for 10PCB

Also there are not charging any extra fees for color PCB. $2 for 10 PCBs (Any Color):

Step 1: Video

Watch video for complete tutorial

Step 2: Item Required

Step 3: Software and Firmware

You need arduino IDE to upload code to arduino

and need a special software to process normal G-code to polar G-code Special thanks to bdring they have developed a software which can convert normal G-code into Polar G-code..

    Question 11 months ago

    helloo, can you tell me which program did you use to send the g-code to the cnc? i am making this project, and i'm using ugs but it don't work correctly


    Question 1 year ago

    could you post the file for the polar conversion


    Question 2 years ago on Step 1

    Can you share the gerber file so I can order the PCB?

    Nice! I love the idea of doing writing on a circular system. As they say, a Polar Bear is just a cartesian bear under co-ordinate transformation. Thank you for sharing your impressive project :-)
