I recently had the same thing happen to me. I would run the cut motor test and it would not run at all (even though it showed that it was running). Lucky for me I have another machine so I just started swapping parts from my "good" machine. I changed out the XBoard and still had the same problem (no running cut motor). I actually took out my motor, opened it up and blew it out. I checked and brushes were fine. I also noticed that on my "good" machine I had those brown glue marks...however it was my good machine that was running fine. Only thing I did notice with (bad machine) cut motor is that it did not seem to be turning as easy when I manually spun the shaft. So I ran my compressor on it a few times where it actually got better. Seems like maybe there was some sawdust that worked it's way in there cause after several passes, it started turning easy again. This might be what caused my board to get hot and cause the "brown glue" heat up on the board.
What I finally did was to bypass the connection from the cut motor to the top lid (connector located on right as you face the flip up window). I know this is not recommended, but I did not connect that and when I ran the test again the cut motor ran fine. This tells me either the connector was bad or likely had dust in it causing the motor not to run. So......... I'm back up and running with both machines. However, here's a pic of both of my XBoards.
