Topic: Da Vinvi Jr filament feeder making terrible noises

My printer starting making noises, so I took apart the filament feeder.  The only thing that was odd was there was black plastic dust in side the case.  So I did some texting and narrowed the sound down to the two "gears" that push the filament.  Is there replacement parts I could try?  Here is a link the the noise: https://www.dropbox.com/s/f6fs31u2kxgq8 … 1.m4a?dl=0

Re: Da Vinvi Jr filament feeder making terrible noises

I know I am really late to the party for this... but if you take apart the feeder you will notice that there is a plastic disk attached to the gears.

What has happened is that the disk has probably came dislodged and is rubbing against something. You might need to re-glue it in place.

Also make sure to clean everything good using the included brush, it might not hurt to check the inset screw on the one gear and make sure its nice and snug.

Here is a post that might help.

Re: Da Vinvi Jr filament feeder making terrible noises

Hello All
I'm new to the forum but have had my DaVinci 1.0 for about 6 months now.
A little over a week ago I had a problem where the feed rollers were making this loud Clicking sound
and at certain points the filament would not come out during a print.
Asked around and it seems that I needed to adjust my bed height.
I did so and afterwards everything seem to flow good.
At this point I started noticing an odd noise, sort of a "creaking" noise while printing which
seems to be coming from the Extruder housing.
Prior to the above the printer was very quiet.
The filament seems to be flowing fine but this noise has me concerned.
Tonight I will be removing the housing and doing a closer inspection.
I read the above link on where the member was having jamming problems
but in my case I am not. Would it still be advisable to look over this?
I guess it couldn't hurt hmm
I have attached a video for your listening pleasure smile
Thanks much in advance

Re: Da Vinvi Jr filament feeder making terrible noises

If your filament is feeding continuously without strange flow problems (too much, too little, varying or unpredictable flow), it could be either that filament dust (or a broken chunk of filament maybe) has simply gummed up the works and is causing some rubbing, or perhaps something was slightly damaged (bent, misaligned). Your earlier problem was filament grinding, I guess caused by the nozzle being too close to the bed, blocking the filament flow. When that happens the hobbed gear will quickly wear away the filament until it can't grip it anymore.

I'd first suggest removing the outer housing and using compressed air to blow any remaining dust away. Check for anything that looks bent or damaged. Make sure that both the drive gear and bearing are tight on their shafts, and can be turned by hand (the gear might give a little resistance but the bearing should be smooth). Also check that the shafts are still parallel and the grooves on the gear and bearing are aligned.

If all that checks out and it still makes noise, try feeding filament with the housing off to try and find the source of the noise. You won't be able to extrude or print like this naturally, but it'll at least tell you where to look further.
