RE: Creaking noise coming from extruder assembly
Hi Makers
This squeaking sound has been driving me crazy since I took my MK3 and transformed it into a mighty MK3s....
I read this post yesterday, while I was still running a long print, anyway, took the idler door off today when I got the first chance I could.
With the idler door off, and that checked. I could see some small plastic residue under the gears, the gears had been rubbing on the top of the PTFE tube and had been making these psycho noises. Anyway a stanly knife blade was used in situ to trim the PTFE tube flush with the black plastic angled support holding it.
Anyway, after assembly, WOW, I am so back to the good old stealth days of mk3'ism.... Sat here close to midnight with the heathy hum of my now mk3S and the silence of the family sleeping somewhere in the backfground......
Long live stealth mode.
Alistair.
Thank you @alistar-m2! This was the fix for mine as well. PTFE tube was rubbing on the metal gear. Cut the PTFE tube flush with an X-acto blade, and no more squeaking.
Well darn it. Was fine for about an hour. Went to bed. Woke up. Started another print, and the squeak is back. Will wait for this print to completed, and will check it again. The thrill of the hunt!
Attempt #2. This time I cut the side facing me. Assuming its rubbing against the gear we assemble. I also put lithium grease on the bearings and shaft this time. Both sides of the shaft were evenly fitted BTW, or none of them ever fell off, as in some other problem/solutions. Hopefully cutting both sides of the PTFE tube and greasing the gear/shaft will quite her down. 30 minutes in and no noise so far. Will see.
3 hours later squeaky noise returned. It appears the PTFE tube rubbing against the gears, is not what’s making the noise for me...or going down the wrong path. I’m going to print a new PETG extruder-idler from Martin’s post next. Sorry for all the previous false positive posts. Wish I could delete them.

(UPDATE: 07-20-2020)
I printed a new extruder-idler with Black Prusament PETG, and the squeaky noise was not there, while printing it. Makes me wonder if its just certain filaments that is making the squeaking noise.
Some others are saying noise will go away after 50 hours or printing. I am 60 hours in. Squeaking noise still there.
Some other posts with lots of validated responses are saying, "It's caused by filament rubbing against the printed extruder parts above the bondtech gears." and reference printing new parts: https://www.myminifactory.com/object/3d-print-86329 . Read the comment section in that link. I will try this and report my results.
If this is the fix.. I was way off base (focused on the bottom, instead of the top). Makes sense actually as there was no squeaking before with the MK3. i.e new MK3S self printed parts being the culprit.
