Just a quick note about the motor brushes...I don't know if the majority of your problems are related to the cut motor or not (I suspect the bit might be "grabbing the wood" occasionally during some of your deep carves causing some of the error messages). However, we can't always tell by looking if the brushes need to be replaced. Mine have been worn down almost to the "nub" and were obviously in need of replacement and was easily spotted just by looking at 'em.
But I had a surprise one day when a friend came over with his machine because he was getting a lot of cut motor errors. First instinct was "needs new brushes". I took out the brushes and they appeared to have plenty of carbon left, so I dismissed the need for replacement...but, since I had some extra brushes on hand, I went ahead and replaced them anyway (thinking it wouldn't make any difference). Well, to my surprise, THAT WAS THE PROBLEM! After replacing what I thought were good brushes with a lot of life left in them, the machine worked perfectly after installing the new ones.
