Hey all, it's time to put together a CNC router. The one I opted for is the Ox machine from OpenBuilds. http://www.openbuilds.com/builds/openbuilds-ox-cnc-machine.341/ This machine uses nearly all off the shelf parts, with the exception of the 4 gantry plates for the X and Y axes. The DXF files for the plates are provided and can be sent to a local shop for cutting from 1/4" material. I had a local laser cutter cut a set from 1/4" aluminum. Here are the gantry plates. I still am going to clean up the edges and smooth out the surfaces with a palm sander: I ordered the 3 NEMA 23 stepper motors off ebay. They're monsters with 425 oz of torque and they only draw 2.8A per phase. Also ordered a 24V 14.6A power supply off the bay, and a TinyG controller from Synthetos. Here's a quick vid of testing the electronics: And a large box of extrusions and various small parts arrived today from OpenBuilds.
