Keep Getting Error 2

I have a Yora silverback and installed a laser on it. At first, I was able to click on the object to burn in absolute coordinates or current Postion and it would travel towards there, but it would only travel about half the distance. Not sure what I did, but now, after homing and then clicking on the object to burn. I get error 2, on or near line 2. Very frustrating. Please Help
