DIY 3 Axis CNC Milling Machine with printer parts

cults3d

INTRODUCTION Why another CNC DIY? After seeing all the amazing CNC machines people were building and sharing online, I was intrigued and started researching. Building my own CNC machine was initially a challenge, but now that it's done, I'm excited to share the design with others. The goals of this CNC project are: - Make it affordable and easy to build - Accommodate large numbers of 3D printed parts - Achieve precise assembly for 3D printed pieces - Keep it compact and rigid enough for printing plastic parts - Mechanize wood, plastics, and other soft materials – I've even tried working with aluminum, but that's yet to be tested Overall dimensions: 430x480x480 Work area: X = 250 - Y = 255 - Z = 73 Largest printed piece: 207x153x134 I'm using GRBL Firmware on an Arduino UNO with a CNC shield.
