Industrial grade CNC router (that can mill steel) with concrete

[Bongodrummer]

Hi friend, this is probably the most ambitious project I've tried - certainly the biggest tool I've made.

It has an 8x4 ft bed to do sheet goods and almost 1.5ft of z travel to fit in big parts, and is rigid enough to handle steel (and aluminium is easy )
Wasn't simple or easy, for me at least, I was starting from zero with this CNC jazz - had no experience with using CNCs let alone building them. Plus I didn't want to go the usual t-slot extrusion route and keep costs very low. So yeah, a big learning experience which I hopefully captured some of, in this ridiculously condensed vid of the build process.
