Idler door not flush with filament inside, unknown if it is an actual problem

So today I had my first real filament jam when attempting to swap filaments for a color change mid print. All seemed fine until I went to put in the second filament and it started grinding, I was able to find help on the website to fix that ( https://help.prusa3d.com/en/article/removing-filament-from-extruder-manually_121491/ ). However, after fixing this I noticed for the first time that the door started moving when I entered in the filament. I hadn't recalled seeing this before, and all else seems well with the printer (although I haven't tried to print anything new after the initial issue).
It's  not "a lot" of bend but enough that I noticed the movement when feeding in the filament. I used about as much tension as previously and it's roughly flush in accordance with the assembly pictures. I've taken some pictures below that show how much the door moves out of the way before and after filament is entered. Thanks ahead of time for the help!

TLDR: I'm just wondering if it's normal for the door to bend or move after feeding in filament into the idler.

yep, based on the images you shown and the description, your idler screw is way to tight. it is however normal for the door to protrude a bit with filament loaded, its designed to do so.

 

Good Luck

It's a spring mounted part; intended to move a little in action.

Cheerio,

The end of my bolt sits more of less flush with the nut on the door and doesn't stick out like yours.  I'd suspect you have the idler adjusted far too tight which would cause grinding.

Have a look at this video here, the idler adjustment is jut less than 1 minute in but worth watching the entire video for tips:

Yea I noticed that as well and backed off the screw a bit just after I took the pictures and tried again but just didn't retake pictures. Thanks all!
