Material 2 Feeder Motor not working

[Pmcging 0]

We have a s5 and I am attempting to load PVA into the Material 2 feed but as I progress through the load steps, the motor does not spin when it attempts to feed. I have taken the cover off the feed assembly to verify the feeder wheels do not spin. We have not used the material 2 feeder on this printer. I have 2 other s5's running 2 materials as I write this. On problem printer, Material 1 loads fine. 

 

Is there a reason this motor would stop working? I have other s5's...would swapping motors be an option? Should I purchase a new motor? Is there a different error I am missing?

Well.. 5.5.x is incredibly old firmware..
There has been.. actually an uncountable number of updates to the firmware since that version number in relation to this issue and the cause of it..

I would recommend swapping motors (and cables) to verify if it still does not work.
If it does not work after those tests, you will need a new mainboard because the stepper driver has died.
