DIY 3 Axis CNC Milling Machine with printer parts

thingiverse

INTRODUCTION I'm driven to create another CNC DIY project, fueled by curiosity and a desire to push the boundaries of what's possible. After discovering the numerous CNC machines being built and shared online, I embarked on an investigative journey to explore this subject further. Initially, building my own CNC was a daunting challenge, but now that it's complete, I'm eager to share the design and inspire others to join me in this creative pursuit. The objectives of this CNC project are clear: * Make it affordable and simple to build * Accommodate a large number of 3D printed pieces with precision assembly * Achieve compactness and rigidity, allowing for the printing of plastic parts * Mechanize wood, plastics, and other soft materials – I've yet to try aluminum, but that's an exciting possibility Key dimensions: * Overall: 430x480x480 mm * Work area: X = 250 mm, Y = 255 mm, Z = 73 mm * Largest printed piece: 207x153x134 mm I've opted for GRBL Firmware on an Arduino UNO with a CNC shield, as showcased in the video at https://youtu.be/Zkqc9dgRoyQ.
