Extruder motor too loud

[ericpudding]

After having installed motor dampeners for all three axis, I now know that the extruder motor is causing the loudest noises in my printer. And If it torque the motor to the side little the noise level drops considerably since the motor is making as much contact to the wood. Has anyone thought of a way to dampen the extruder motor?

I loosened the screws put felt between it and the board and stuffed felt on either side of it in the small rectangle cutouts. Thus making sure it did not touch the mounting board anywhere to transmit sound. That dropped the sound to almost nothing. I could not see any reason why it need to be tight to the structure. It has been working that way now for several months.

My extruder is ridiculously loud too, resonating noise from the arm into the top where its being amplified. I'm going to try the felt idea, I'll post back if its successful.

That wood arm transmits all the vibration of the extruder motor into the top hollow base. It amplifies the noise significantly.

That is the best solution IMHO. I have to rig up a similar solution - I also stuffed some A/C insulation in the top to reduce the overall vibration and that seemed to help a little bit as well. It's the same concept as putting cork/astrodyn dampers on the XYZ motors - get them off the wood and you reduce the vibration through the entire thing.

If they ever release the V3 or update the V2, it should include dampers as a part of the normal build procedure.

I did the felt thing too. Just 2 small strips jammed along the bottom left and right corners. Made a HUGE difference.
