MMU Filament Selector Stepper Motor Grinding During Homing

I have been having issues with my mmu loading so I broke it down and got it going but now a new problem as risen. During the homing movement, when it gets past the 5th slot and it is suppose to do that hit and click a few time and be done, well now it will just grind for about 15-20 seconds and then will continue on it path. Trust me this does not sound normal. 

There is nothing in the way and the threaded rod and smooth rods are all clean and lubed up. Any suggestions?

Sounds as though you have the Mk3+MMU2?  This is the Mk2+MMU section.

I will see if I can get your post moved...
