Turned my $600 MPCNC into an aluminum-cutting beast with about $500 in upgrades! Full enclosure, HGR15 linear rails, T-track for workholding, cable chains, anti-backlash Z drive, and a Raspberry Pi for CNC.js.

* I will publish a discussion video about this build for anyone who wants to learn more about it: [Video TBD]
* 3d model for the HGR15 linear rail upgrade (please read the description regarding stiffness): www.printables.com/model/8358...
* The rails were cheap-but-good-enough Chinese rails from Vevor. About $90 for 2x 1,500mm and 4x glide blocks! Here's the link (not affiliate link): www.vevor.com/linear-guide-ra...
* The QQQ system (referenced at 07:40) is best suited for a table saw with a dado blade setup, but most of the cuts can be done on a single flat sheet using a CNC. You only have to flip two pieces and make a single dado on each to complete it, which I was able to do with a CNC.js macro. Original source: www.thisiscarpentry.com/2014/...
