Boss-level upgrades to my CNC machine

Описание к видео Boss-level upgrades to my CNC machine

The MPCNC is a cool DIY CNC router. But I wanted to use it for more than it was designed for -- cutting aluminum. Weeks of design and assembly made that dream a reality. See how I did it and enjoy the twists and turns of improv CNC engineering!

The original build was about $600 including all the electronics. This upgrade added about $500 total:

Raspberry pi: ~$50
Linear Rails & glide blocks: $65/2= $33 (I only used 1 rail + 2 blocks)
2020 and 2040 aluminum extrusions: ~$150
Fluted Polypropylene (sign board) for side and rear panels: $30
Cable/drag chains: ~$50
T-Tracks and clamps: ~$50
Other (wood, fasteners, etc): ~$100
Acrylic door panels: ~$40
