I am working on a system that will drill holes on a ribbon wire. The wire is continuous in length and comes off a roll. I plan on using a take up roll to advance the ribbon. As the take up roll gets more wire on it the diameter will change so I have an encoder wheel that can measure the distance the ribbon travels. The machine is basically a 2 axis (X and Z). I will drill a hole then move 0.2" drill again and repeat every 2" down the ribbon. I am thinking that I might need to do this through brains or c code. Unless there is a better way. Thanks for the input. Eddy
