Hey guys. I'm doing a mini project for the high school in my area. They found a MaxNC 15 covered in dust. I've managed to get it working, it uses an older version of the control box that manually controls the speed of the drill bit using a black knob. It turns on and works, They also have a lathe attachment. I plug it into a pc using a parallel port but it doesn't seem to read it. I tried several programs to no avail. While I was researching throughout the internet people have been saying that I should scrap the controller and build my own. Problem is i have no clue how to. I searched a bit and was wondering if I would be able to use a TinyG as a new controller for it. Any thoughts?
These are the specs on the website for the mill but the controller seen on these pictures has 8 cables protruding from it while the one at the high school has only 3 cables and a black knob
