First off lets get a project started. I just bought a whole crap ton of this...
Basically the failures of my past attempt at building a CNC machine could be summed up in several things....well one. Hand tools are not very accurate in my hands. Ive performed a lot of things with hand tools. Anything from hanging drywall to cutting the frame of a truck to add air ride so Im pretty capable of most tasks. But cutting a perfectly straight line for 48 inches is just as hard as it looks using a skill saw. This is where the T-Slot (extruded aluminum) comes in to play. Its straight and easy to tweek if its not perpendicular.Its cheap enough to get in mass quantities from eBay and hopefully easy to work with. That point will be determined when it gets here in the next week or two.
Keep a look out for other posts pertaining to a couple arduino projects Ive got going on and possibly the rooting of an EVO 3D.
