Okay, it's actually a REbuild. I 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.
* If you're new here, watch the first video showing how I built the original machine for $600: https://youtu.be/VFPeR6i1BvE
* 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): https://www.printables.com/model/835864-mpcnc-primo-c-hgr15-upgrade-files
* 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): https://www.vevor.com/linear-guide-rail-c_10531/15-1500mm-2-x-linear-guideway-rail-4-x-square-type-bearing-block-hgh-15ca-p_010407324347
* 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.
