It’s a Blurry Customs mill http://www.blurrycustoms.com/ , with modifications. I got it a few years back when prices were a bit better, it’s just been an “in the works” project. All the blue plastic pieces came off my Taz, the sideplates of the Z axis column, the bed, and my attempts at swarf guarding are modifications, with a STDR4C http://www.soigeneris.com/stdr_4c-details.aspx control box tied to a USB smoothstepper and a Gecko G540 4 axis controller (currently controlling 3 axis) . The flood coolant thingy is also a modification.
Next steps will be finishing the basin base for the flood coolant system, waterproofing all the cables, and then assembling the upper guards.
I bought this particular mill before Blurry Customs had a few less than quality mills released that hurt their reputation a bit (you can see those threads if you do a search) but this one is very solid, square, and seems to have no problems whatsoever so I can’t say I have any complaints with it.
