I haven't yet built the machine, so that probably is my problem. But, I've downloaded and/or bought Rhino3d/MadCAM/Mach3 and can't seem to find the answer to a very obvious question:
How does the CAM software know the dimensions of the rough stock I am milling the parts from? MadCAM seems to just generate a cube around your model and assumes that the stock is going to just fit the part. I want to work in wood. Where do I tell the software what the block I'm cutting from actually measures and where on the block I want it to cut?
Again, sorry about such a basic noob question. The answer is probably obvious, but sometimes when you are working something out by yourself you just blank on things.
