I think you really need to get a pro out to inspect the entire unit. If you have the feed rate wide open and set it to the QUAD setting that thing should be ripping so hot it trips the over-limit sensors on the unit (Yes I had a customer do this, they actually disengaged the feed rate slider off its track and bent it all to hell).
Again, nothing beats a trained set of eyes on the thing. I suggest a pro to do a full cleaning and inspection of all components and functions. If you do have someone come out, let them know about all the things you have been tinkering with so they can set it all back to factory default settings.
