I bought the HobbyCNC 200oz kit, primarily for cost, and I actually enjoyed putting the board together. The motors seem to have plenty of power and speed for my JGRO using 1/2" Acme lead screws.
For the aluminum angles, I marked the space to be cut on the angles with a Sharpie and took most of the material off with my bench grinder. The width of the cut isn't critical and the size of my grinding wheel was just about right. I finished it up the cut with a hand file to get it flat.
If you don't have a grinder, use a hacksaw and make multiple kerf cuts, then finish it up with a file. It's also easier to drill the holes after the flat is cut. |
