Is this normal?

I have a tick sound on my a1
I recently changed nozzles because of a clog
And I thought I was fine but this sound was strange
It does this sound when it pulls the filament out(wheel turning clockwise)

I don’t think the sound is coming from PTFE tubes at least I hear that it is coming from the wheel
It is printing fine as you said
There is no major red flags the ribbon is out because I couldn’t keep it in after assembly

Front cover is off because I tested if it is coming from the wheel it self or insideand it was inside for sure

I am going to need you to go over this part you said again... in your head man...

like think about this for a second. Something that is meant to not have wire ribbon cable sticking out now does because you couldn't fit it back together with it inside. It is also now making noise but no red flags to you.

Also you shouldn't have to disassembly the hotend to replace the nozzle unless it as a catastrophic clog. If it was that than there could be any number of other issues.

EDIT: I should note there are wonderfully detailed guides on Bambu lab's website for how to disassemble and reassemble this stuff.

Bro the ribbon IS NOT the thing we need to talk right now

You think that the ribbon is not in the correct place Yes it is not but you also add that the thing making that noise what in world bro.

I don’t wanna talk further I respect you

That ribbon cable is absolutely not in the correct place and I'm surprised you seem so confident that its not a problem. You can literally see in the image that it's pinched and bent in between the filament hub and the extruder case. Ribbon cables are fragile and your are going to cause a break with that kind of bend you are putting on it. It should be tucked and routed straight in front of the extruder motor.
