Sorry, I'm not trying to be funny or rude. The issue is that in order to fix this, the machine told you there was a hardware problem. There is no magical fix I or anyone else is going to tell you about the 5th gen system.
It's closed source, MakerBot honestly doesn't event want us a community messing with the machine- they want you to call them and all support through them.
The days of tips and tricks is over.
