Homemade CNC with 3D Printed Parts - Redesign

Update 28 sept 2019: I’ve created a new version, check it out here: --- This is the second version of my DIY homemade CNC. It’s a complete redesign because of some issues that I’ve had with the first one. The main issue with the first version was that the wooden Y axis was getting warped (by moisture I guess). Also the bearings were too small and the aluminium X rails were not strong enough to carry the weigth. That’s why I’ve switched over to use 20mm x 20mm square steel tubes for both Y- and X axis. I’ve designed the 3D printed parts with Fusion 360 and used Inkscape for the Y axis drilling template. To control the machine I’m using an Arduino UNO with GRBL firmware and an Arduino CNC Shield. There are plenty of tutorials to find on how to connect and use it so I did not show it in the video. Here are some useful links: * [GRBL]() * [Arduino CNC Shield]() If you want to build one yours
