MMU Help Please

Well this has been a bad experience to say the least. Very disappointing that Prusa does not offer a completed package for multi color. 

Can anyone help me understand why the (brand new) extruder now has a bad clicking sound internally after I put the new items in it for the MMU upgrade? What can I look for while disassembling this?

Something else I do not understand is now after slicing a print it looks like the layer height is like 10mm not .2. I've tried to add a pic in these posts but cant so I apologize.

Hi Joan

I tried insert pic and attach a file and they did not seem to work ALTHOUGH it does appear now that there is a clip in the post that was not in preview. Do you see this "Duck-snip.PNG"?? I have just figured out the PLA has now jammed up the heater and nozzle on the extruder (never before happened) so I am in the process of pulling all back apart. I hope the snip shows you more about what I am asking.

Thanks for the reply

Kinda owe Prusa an apology

Well after a bit of beating my head against the wall and yelling I have finally figured this out. I will say this is a game changer for me and it appears its working perfect for now. I did want to blow this up but now I want to hug it. I really think Prusa should put just a bit more time in on manuals and make them dummy proof but I understand its difficult to get that done. I hope there are no more issues going forward.
