I can't remember what happened to tell me to check the brushes - obviously something stopped working. I can't believe I didn't ever check them before they went bad. There was about an 1/8th of an inch left of the brush part before going in to the spring. In fact, I felt like an operating doctor trying to get the part out because there wasn't any 'spring' left to the spring to pop the brush out it was so far gone.
I'm usually pretty proactive about machine maintenance, but completely overlooked the brushes.
The sensor is going to be ordered and replaced soon. I'm pretty sure that is the problem for this time. We have little humidity issues this far in to the valley on the west coast - nothing like the eastern part of the country. I'll start with the sensor and see where I end up. With a machine this old, it could be multiple things going on.
I've really decided to keep this machine going because I love it, but I will be purchasing a laser also, hopefully in this year. That will help if the engraver ever goes down - back up machines are great to have. Lessens the stress factor by a bunch.

Your description tells me why you replaced the brushes. It started sputtering, going intermittent. Some brushes are made with short springs to cause that to happen. others have a slot down the side that ends near the spring. There is a tab in the housing that latches on to the end of that slot when it gets too short and stops the brush from being pushed any farther.
The Dahlgren motors used the slot system and saved many motors. Of course the RF snubbing system in the motor burned out the commutator really fast, duh.

This is how I felt when I saw those brushes
:-$
I was so ashamed of myself for letting it get that bad.
