Topic: Need to replace broken selector knob for Fireface UCX

heylo all!

a friend of mine's roommate dropped a stack of books on a table next to my UCX. the books caught the selector knob and broke it off. i've tried super gluing it back on, but it doesn't stick out far enough to push it in.

i'm thinking i should just replace the knob with a new one.

this will be very easy or very hard, i think. smile

any ideas?

thanx!
b.p.

If the shift broke off then the encoder on the PCB behind the front needs to be replaced. Very hard, then.

Re: Need to replace broken selector knob for Fireface UCX

the selector knob technically still works. using an object, i can push in the knob and select just fine. when i glue the broken piece back on, i can rotate the knob with no issues.

the problem is that when the broken piece is glued on, there isn't enough of a gap between the knob and the plate to push the knob in.

Re: Need to replace broken selector knob for Fireface UCX

Hi all,

I was wondering about a reply to the last post here.

I have the same issue. The button response when I push it in a certain angle (and no other issue with the device). I think its only the actual plastic knob that is broken.
If that's the case- Is it possible to DIY? by ordering a new encoder from your shop?

bump....

any luck finding a replacement for the knob, leftech?

Re: Need to replace broken selector knob for Fireface UCX

I'm needing the same knobs... My local dealer was supposed to get me some before Christmas but has never gotten back to me.

It would be nice to order them directly from RME.

Re: Need to replace broken selector knob for Fireface UCX

my UCX isn't under warranty anymore and  Synthax says they'd have to replace the encoder. they didn't give me a cost estimate, but i'm thinking it'll be more than i want to spend.

i don't care if it's the exact knob. i just want to find another knob i can fashion to superglue onto the stem i have left.

any suggestions on where to find something that could possibly work?

Re: Need to replace broken selector knob for Fireface UCX

Sorry for the kind of necro but...Have you managed to replace the knob yourself?

Re: Need to replace broken selector knob for Fireface UCX

Hello, I had the exact same problem with my fireface uc. I also saw a person selling his ucx for 500 € on willhaben because of the broken selector knob. The knob looked exactly like in the photo, with one part broken off. What I did, was the following:

Purchase a replacement encoder on rme.

https://www.rme-shop.com/acatalog/RME-- … -3534.html

plus the cap, because it was glued and i could not get it out.

https://www.rme-shop.com/acatalog/RME-- … ml#SID=113

THis is for UC, for UCX:

https://www.rme-shop.com/acatalog/RME-- … ml#SID=113

The parts came with PostNL out of the Netherlands, the ratings are very bad for this carrier, but I had absolutely no problems. Only thing is the tracking link does not work sometimes, so you have to enter your barcode on postnl tracking page

Then I saw, how the status changed. Can take up to 2 weeks, but better than no knob. Patience is key!

So then, the encoder and the cap came. The encoder normally gets soldered on the board but it still worked with the old knob (very loose and wobbly), so I though why not only put the one black part in. So I disassembled the encoder. I bent away the metal pins, disassembled everything. I cut the plastic (yes, you heard right. I cut it open with a knife) and got to the part I only needed. Then I put the new cap onto this part and put it into the hole and voila!!!! It worked. Now I have a working knob again and I am very happy not to have to pay repair costs which probably are high. I´d love to post some pictures of the process, but I am no admin. I also hope in the future RME will make solid knob solutions and find a better solution for this, because this knob breaks off a lot it seems. Especially with such an expensive device, I am disappointed that the knob breaks off so easily (I broke it off with my spinning chair) When I look at the audient id14 I had, never would there have been the possibility that the knob breaks off.

Here are the photos. You can see I disassembled the encoder and put the knob back into the UC and it works now. I hope this helps someone with similar problems.

Re: Need to replace broken selector knob for Fireface UCX

Hi, anyone knows if these would be the required parts to repair the small knob of a UFX+?

Re: Need to replace broken selector knob for Fireface UCX

Here is the state of my encoder that still somehow works:
https://i.ibb.co/VLRs9zH/20230520-103943.jpg

I also thought, at first, a new plastic attachment part could be inserted instead of the broken one to avoid soldering. This idea seems to work for you fritzi on a Fireface UC.

Seems an interesting thing to try instead of :

  • Sending the interface to a first company (I'm not living in Germany) without any idea of the fixing cost

  • Having an estimate established by first company. If I refuse the estimate, I'll have to pay for the time spent on estimate. No idea what it could cost.

  • If the first company is not able to fix it, the UCX will be sent to RME for fixing

  • All in all, a probably lengthy and costly process with some risks included

I'd really like to keep my UCX working. Don't think the world needs more interfaces sold for the sake of a broken knob wink
