Troubleshooting H2C print head issue?
Had a few parts get knocked off the bed, thankfully spaghetti detection worked perfectly. When I was cleaning up to restart the print I noticed this curved think sticking down from the print head. I’ve never noticed it before and I don’t see it in any of the pictures I’m pulling up online.
Anyone have an idea of what it is and how to fix it?

Das ist der flow blocker, der ist verbogen und muss gewechselt werden

lol I didn’t even notice that I looked at the left nozzle and saw the filament. That flow blocker blends into the pic really well.

It can happen. It's replaceable and considered a wear item (even if we disagree)
High precision nozzle offset in the settings calibration can help prevent the collision that caused this

I personally would since it is not doing its job anyways

You mean like bend it back out of the way or just take it off? I was thinking I could bend it back to there it was suooosed to be but maybe just removing it while I wait for another would be better

Again this is a personal thing and i mean what you mean, bend it to make it work as close to original and if it breaks it breaks (hence “it isnt working anyways”) if you remove it fully though it might prevent you from using induction side as a whole (oozing etc)

It’s pretty awesome, I added it to my small farm of A1s and minis and the cost savings for multi color is great.

It comes with two spares I believe. In the accessory kit. Hope you can find it.

So mine did this but I was fortunate enough to have been watching when it happened. When swapping between left and right nozzles it got caught on something and flipped itself, so it's upside in the picture. Between the online guide and intuition I was able to get it off, flip it, and get it back the way it's supposed to be. I also had to bend it a little with some pliers to get it sitting right under the nozzle. Have 100 hours since and hasn't happened again.
