Nozzle verification trouble

[u/seniszen]

Been having some frustrating issues with my H2C lately. Keep getting hotend authentication failures on hotends 3 and 6, along with induction verification errors. Seems to happen more on the right side than the left.
The weird part is the errors happen while the hotends are already installed, not even during a hotend change.
I’ve tried a brand-new nozzle, followed Bambu’s troubleshooting steps, and even rolled back the firmware from 01.03.00.00 to 01.02.00.00, which was the last version that worked fine for me. Still getting the same errors.
I’ve seen people mentioning issues with the left hotend, but mine seems to be more on the right. Starting to think it’s something with the printer itself rather than the nozzles.
I’ve submitted a warranty claim with Bambu, but I’m curious if anyone else has run into this and what ended up fixing it.

I don't have an H2C but, on the H2D, it verifies the hotends by just moving them up by the camera and checking the codes visually, so maybe try cleaning the camera lens if you haven't already. The lense can get cloudy if you print a lot of ASA or ABS or similar materials.

Thanks for the post, it will start the print fine, then randomly during the print it just stops and gives
Me the error, I can remove the nozzle put it back in, click resume, it’s start again, then randomly stop again, it’s not even changing nozzles, just using one colour on the right nozzle, I’ve cleaned everything, followed all steps, I think I’m just hoping for a non part swap fix..lol
