For a project for school I am making a game board. Its a pretty simple design and all, the only thing on it is letters carved into the board. But for some reason when I go to start the operation on my schools milling machine there are two things that happen. Either there is an error message that pops up and says "Run Time Error Subscript Out of Range". Or the spindle will start up and the program will say that the machine is paused and even if I click resume it won't let me resume the operation. If anyone could help it would be greatly appreciated. I attached the file as well.
