okay I completely dis-assembled and re-assembled the mmu... did the upgrade  on the back ptfe tubes  with thread in holders.  replaced the PTFE tube with capricon tube.   The mmu loads irraticaly  (sometimes to the wrong location), does not eject fully, sometimes.  When I try to load to nozzle it wont load( end clipped at a sharp angle).  The extruder bondtec gear spins so fast it is hard to even see the gears.

Im done...friends who also have a prusa mk3s dont even want the unit to try.  Back to the Pallatte 2,  after  a day  I was printing 4 color minions...20 hr prints and 744color changes(splices). I will figure out the pallattes  dislike for solubles.

I was interested in the up comimg larger Prusa printer...now I am reluctant.  Thanks for  help from the readers.

I would most definitely contact support.  Something is wrong with the loading and unloading.  They (support) can most likely help much better than we here on this informal forum can.
