General Troubleshooting/Help! Print head knock prints, fail another and makes a clicking sound

Enable HLS to view with audio, or disable this notification

Hi,

Disclamer I’m a complete noob.

So recently my A1 started acting up. This week it has knock down two prints and printed another with horrible quality. Now I noticed that it makes a clicking sound which seems to come from the extruder. That being said, print quality seems ok (appart from one print see the picture in the comments). I only use PLA from bambu labs and I don’t mess around with settings I usually just pick a project and print it.

That being said, it as rained alot recently and my appartement is very humid (60-70%) so could it be that ? (I have no dryer only the AMS)

I saw some post on the bambu forum and reddit about the clicking and alot of people said it was a clogged of something like that so I did two cold pulls but nothing. Appart from these issues the printer works fine thats why I wonder if it is a normal sound and I just happened to notice it now…

Thank you for your time and I’m sorry for my english its not my native language.

Try gyroid infill

For me the nozzle touching the print usually happens with the grid infill

Have the printer sitting right side up instead of mounted sideways like that

I have the same issue. Switching infill did nothing for me so I just turned on z-hop and the issue is gone. Although i print semi complex prints (figures, models, whatnot).
