Being a field service technician means working weekends.
Today's job, machine keeps running after stop button pressed, serious safety concern.
My money's on a missing or inverted index signal at the encoder.
Best way to confirm... put an oscilloscope on it. Multimeter won't show you a dropped pulse.
This is the kind of fault independent FSTs fix every week.
