Clicking sound on bondtech

Recommended Posts

Hello !

I recently changed my PLA supplier (now PLA economy from Colorfabb) in 2.2kg spool and I started to hear clicking sound on both my UM2+.

I have bondtech feeders, tinkergnome and (normally) I set everything up correctly. I do not have underextrusion at all... I tried to loose the tensionning screw on the feeder and to increase the printing speed but I still have this (VERY ANNOYING) clicking sound. It occurs each 5 or 10 seconds.

Maybe I did not hear it before because of the size of the spool and the lack of resonance... 

Do you have an idea ? 

 

If you need any extra info and/or pics, do not hesitate ! I am note sure what could be of use here...

 

Thanks a lot ?

If you start to hear clicking sounds when putting a 2.2kg spools on the back instead of the standard 750-1000 gram, the last thing you should do is speed up the print, and loosen the tension, try the other way around.

thanks @phantom

the problem was the increased friction due to the increased weight of the spool

the tension was building itself on the filament guide and every 5/10 seconds the tension was released and it "clicks"

I strongly advise a separate spool holder for this size...

Now the spool is on a spool holder with bearings and there is less friction than with a regular spool (but it's taking a lot of place XD)

I took care of the angle from which the filament enters the feeder and it's printing like a charm now !

Thanks @phantom ?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
