Plywood Arduino Based EggBot

prusaprinters

EggBot is a machine that can draw anything you want on an egg. It's a great introduction to CNC machining and a relatively inexpensive project to build. And it's a lot of fun once it finally works.More info in the video:The list of parts is quite short for this project, basic soldering skills might be required. I am adding links to some parts, some parts (laser cut and 3D printed are explained in depth in next steps):Arduino UNO - you can use any Arduino board you want, Arduino is the most basic one and is very popular. You can use a clone board (not a original board from Arduino, in most cases it will work just fine)Stepper motors (Nema17) - I tried experimenting with 28BYJ48 but the backlash is so terrible that there is just no way to get it working fine in such a project. You can see 28BYJ48 on the image above, I took this picture while starting to work on a project, I advise you not to use these motors.Micro servo motor - the most popular 9g blue micro servoA4988 stepper motor drivers - incredibly cheap stepper driver that was widely used in 3D printers, you can also use some TMC drivers if you want it to be silent.Breadboard - here we will attach stepper drivers to the Arduino, alternatively, you can use a GRBL shield or a proto shield with breadboard mounted on top.Some cables - breadboard male to male cables.608 bearing - this will let the egg rotateSome M3 screws3D printed parts and laser cut plywood parts - you can buy a kit of those parts from my store: https://indystry.cc/store/ My Instagram: https://www.instagram.com/nikodembartnik/And patreon: https://www.patreon.com/nikodembartnik
