CNC, Pt. 4: Frame Construction

Construction begins! It's pretty straight forward, just start building in reverse of how it was designed- steel frame first. It is very important to be as precise as absolutely possible when constructing the frame since the rails are bolted directly to it, and you only get about 1/8" of adjustment or less when it's all said and done. Those rails, when locked down, need to be withing about 1/100th of an inch of perfectly parallel or they will bind up and bring the machine to a disappointing halt.

Once the frame was done we mounted the rails (loosely) by drilling and tapping directly into the steel beams.
