Boss-level upgrades to my CNC machine #mpcnc #hackaday

This video made it onto hackaday! https://hackaday.com/2024/05/07/mostly-printed-cnc-gets-a-few-upgrades/ 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 Links: * 3D printed anti-backlash TR8 leadscrew thingie: https://www.printables.com/model/729791-printable-anti-backlash-fixture-for-dual-tr8-leads * HGR15 linear rail adapters: https://www.printables.com/model/835864-mpcnc-primo-c-hgr15-upgrade-files ===TIMELINE=== 00:00 Opener 00:59 MPCNC Intro 01:48 OG Build Review 03:26 Linear Rail Upgrade 06:43 Anti-backlash Z-screw 09:36 The Fancy Enclosure 11:27 Raspberry Pi + CNC.js 14:59 Closer
