Squeaky Servo
The Glentek DC servo on my X axis squeaks when it rotates under power or by hand.
I removed the brushes and rotated and it's whisper quiet. Brushes look fairly new.
I blew all the carbon out and rotated the armature while blowing out the commutator.
It squeaks as soon as I installed the brushes. None of the other motors make any noise.
Why is this one make noise and the others aren't?
