after installing the MMU I think I’ve got it working but the printer is really loud. When moving the extruder or the bed (can’t tell which is causing it) it seems to occasionally have a loud grinding noise.

If anyone is having this problem- I figured it out. 

 

1. The MMU Buffer hooks according the the instructions are on the top and if you hook them on the back of the printer it actually blocks the bed from moving all the way back which causes tons of issues.  I ended up inverting the hooks on the MMU Buffer so they hook on the bottom.  

2. After that I had to do a layer calibration.
