I just finished a print and on the print plate I found a small black plastic rubber thingy. I tried to look for missing/broken stuff, but couldnt spot it.
Any chance anyone knows what it is and what I need to buy/repair?
thanks

I think that’s the backside of the hotend heating assembly.
Take a look here:

Thanks! So I would need to buy a complete new hotend then?

I had the same with mine. Support told me to buy a new heating assembly. So far I haven’t noticed any problems with the part missing. Should keep the cable in position but they are so short there isn’t any movement anyway.
So does this appear to be a design or manufacture issue? From man1ac’s photos I thought it looked like maybe the wires had snagged but the photo from seahawk137 that doesn’t seem to be the issue. Is it getting hot and brittle?

It’s pretty clear that yes, there’s a manufacturing problem with this. I’ve only got 300 hours of printing on the P2S, with PETG, 255–260 °C… this is a huge pain to happen at this time, all the holidays with the machine down.
The A1 has a similar footer. IMO it’s doing its job, guiding wires without sharp corners or heat transfer. It’s a similar material as the nozzle sock, but a harder durometer. It’s closer and more exposed to the heater element than the sock is so its gonna be sacrificial. That being said, I havent had them fall apart on their own ever, only when I was also unscrewing stuff and already noodling around. Do you think yours self-destructed, or did it fall out when maintaining?
PodrĂa atribuirse a un manejo incorrecto, aunque sigo creyendo que una pieza de silicona bien diseñada no deberĂa romperse tan fácilmente durante la limpieza… Sin embargo, en mi caso especĂfico, eso no es lo que sucediĂł. No toquĂ© la pieza, ni cambiĂ© la boquilla. Las dos piezas que encontrĂ© muestran un claro cambio en la textura debido a la degradaciĂłn del calor; han perdido tanto la elasticidad como el color. Puedo entender que su funciĂłn es proteger el cable y que podrĂa ser una parte consumible… pero si ese es el caso, entonces lo fabricar y venderlo como tal; no fuerce la compra de un conjunto complejo de 38 € para reemplazar un consumible que cuesta 0,20 € al menor.
Ahora, mis preguntas son:
- ¿Asumirá Bambu Lab la responsabilidad de este fallo?
- ÂżEsto se puede reparar usando cinta Kapton y silicona a alta temperatura, por ejemplo?
Incluso si es reparable, es un dolor tener que quitar los tornillos cada 150 horas… especialmente teniendo en cuenta que Bambu Lab ha quitado los insertos roscados en esta impresora, y los tornillos van directamente al plástico. Esta impresora no será tan indulgente con el desmontaje repetido como lo es la X1C…

@albertoFabricacion, I hope you don’t mind, I ran your text through Google translate so I could read it and am posting it here. Hopefully it did not change any of what you were saying.
@albertoFabricacion, espero que no te importe. PasĂ© tu texto por el traductor de Google para poder leerlo y lo publico aquĂ. Espero que no haya cambiado nada de lo que decĂas.
Translation:
This could be attributed to improper handling, although I still believe that a well-designed silicone part shouldn’t break so easily during cleaning… However, in my specific case, that’s not what happened. I didn’t touch the part, nor did I change the nozzle. The two pieces I found show a clear change in texture due to heat degradation; they’ve lost both elasticity and color. I can understand that their function is to protect the cable and that they might be a consumable part… but if that’s the case, then manufacture and sell them as such; don’t force the purchase of a complex €38 kit to replace a consumable that costs at least €0.20.
Now, my questions are:
Will Bambu Lab take responsibility for this failure?
Can this be repaired using Kapton tape and high-temperature silicone, for example?
Even if it’s repairable, it’s a pain having to remove the screws every 150 hours… especially considering Bambu Lab has removed the threaded inserts on this printer, and the screws go directly into the plastic. This printer won’t be as forgiving of repeated disassembly as the X1C is…

same issue happened to me tonight, less than 300 hours.
mostly printing with PLA, tried PETG for the first time tonight and it clumped up at the nozzle, while I was cleaning it the rear sock disintegrated into pieces
Erlich gesagt hatte ich das gleiche Problem an der rechten seite einfach ab gegangen .
ich drucke seitdem ohne das kleine teil hab es mit Hochtemparatur Silikon einen tropfen drauf gemacht und hält schon seit zahlreichen drucken ohne Probleme.
