[UM2 to UM2+ upgrade - did I break it?]

Thanks for the replies.

 

I know what happened now:  The little pressure indicator thingy popped out of place when I first took it apart and then I put it back together wrong. 

 

I took the gearbox off and rebuilt it using that guide.  I just printed a test robot and it looks great!

[UM2 to UM2+ upgrade - did I break it?]

I did the upgrade kit to take my UM2 to UM2+.

 

At the point where you install the new the geared feeder, I couldn't immediately get the metal mounting bracket off, so I thought I should try unscrewing the 4 screws on the face of the gear box.  I heard and felt what seemed like parts under tension shifting around when the screws came out.  I'm guessing I broke that piece?

The piece I'm talking about is at: https://ultimaker.com/en/products/extrusion-upgrade-kit

If you scroll down to "What's the in Kit" - it's #4

 

 

On a different note, the black braided bundle of hotend wires comes out right where the PLA goes in from the spool.  Seems they will rub on each other, which seems like a bad thing.

Is this a known thing?  I was going to do something janky to force the black bundle out of the way to the side. 

 

Thanks!
