I have a plasma table that I believe the controller is bad in. I can start up the machine and software. I was able to home the torch. Then when I went to run a program, I would get a message stating "surface block not detected". I am new to the company. The issue happened before I started. The company tried switching out controllers with another controller we had in house. This did not fix the issue. Is there a way to reprogram the controller to work again, or do I need to buy a new controller?

Thank you for any input on this subject.
