Cheap CNC Router
thingiverse
A homemade CNC machine with 608zz bearings and plumbing pipes is showcased in a new version available at http://www.thingiverse.com/thing:1659021. The BOM includes materials like plumbing pipes, 608ZZ bearings, U-bolts, threaded rods, aluminum angle, MDF, stepper motors, a Dremel, and electronics. A cheap Chinese stepper driver board from eBay was used, but it may have issues with missing steps. Better options include Gecko G540 or breakout boards combined with the cheap drivers mentioned in the BOM. The software used are Mach3 and Linux EMC2, while Lazycam is the CAM program. A poor video of the machine in action is available at http://www.youtube.com/watch?v=MEzmb7wuGx0, but the creator may add more instructions if there's interest.
