Hi guys, so this instructable will help you out to make simple, less budget Arduino cnc plotter.
In this project i had used some recycled parts like printer rail, smps box cd drive mechanism etc..
so the supplies that you should buy are less and less in cost too.
I was very curious about all these kind of stuff so that i had started building this project couple of months before. well i thought i can draw the school records using this great 2D machine. This instructable will cover almost all the area to build a high quality cnc machine.
Firstly I will step into building the mechanical setup of the cnc machine. I had used Fusion 360 to express my idea into reality in making this project. Since i am using Fusion 360 for first time, I took lots of time in designing some of the parts. I have given the resultant model below.
Coming back to the software and hardware parts, I had used Arduino UNO ,which acts as motherboard for this project. Used grbl v1.1h. I will give a detailed explanation on about how to load firmware, creating custom G-Code, handling the user friendly G-Code Sender.
And you can use this machine to draw birthday cards, record drawing works,writing letters,decorating pages with your own ideas…… :).
