UM2 to UM2+ upgrade - did I break it?

Recommended Posts

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!

Well, there's a spring inside...

This guide contains a lot of pictures:

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!

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
