Homemade CNC with 3D Printed Parts

Update 2018/08/18: I’ve made a new version, check it out here: This is a video about making my homemade DIY CNC with 3D printed parts. I’ve designed the 3D printed parts with Fusion 360. 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: To power the NEMA 17 stepper motors I’ve converted an old ATX PC power supply and used the 12V output. The type of stepper motors I use for the Y- and Z axis are: 17HS19-2004S1, the type for the X axis is: 42BYGHW811. For the wiring I’ve used CAT5 network cable. Software that I mostly use to generate and send GCode: bCNC () Universal Gcode Sender (
