Hello, new to cnc, when I watch the video's I can see the road runner drawing loaded and I can see it in the window, when I load it, its the size of a pinhead. I can use the mouse wheel to zoom, but that takes an hour and it never really gets to the size I want to see. The same thing happens when I create my own drawing? I can start the program and it runs, but the mill never moves more than an inch if even that. my spindle motor is not working yet, so I'm just trying to do test runs, just set it up, think its a bad board, hope it does not take long to fix!
