I'm seriously looking for ways to eliminate every printing sound. I already managed to reduce the noice by finetuning stepper currents though according to my neighbour it's still to loud. Mentioning the noise level from a recent party in his house didn't seem to even things out. Not sure if it is me but I really spend some time to reduce noise and I still get complaints...
Any idea's what might help?
I've played with a foam pad that reduces the vibrations in the base (that acts like a sound board)
I finetuned the stepper currents. this worked fine for the X an Y but the Z axis is just VERY loud compared to the rest. (and i think that this is mainly what leaks trough to my neighbor.)
The beltdriven Z axis looks like a step in the right direction.
Spikes, like the ones used to decouple loudspeakers from the floor, didn't help at all. In my case the table top all of a sudden incarnated as a sound board and it resonated most at the frequency of the Z axis motor. So this actually resulted in more noise.
Also stepper decoupling with a gasket is something I still have to try. But since the Z motor is part of what makes the Z axis more sturdy that just doesn't work. If i put a gasket or rubber rings between Z motor and baseplate then that affects the straightness of the Z, and it also makes the Z 'flexible'. All in all not a good idea..

The Z-axis mainly screams when doing the bed level probing.
I don't have a video camera I soon will upgrade my stone-age spy device that can also make phonecalls to a more versatile spy device. :-D

O thanks!
I’ve played with the acceleration though haven’t yet touched the feed speed. What are your settings? Then have some idea in what range I have to be.. I’ll put them in and have a listen. I see I need to learn a lot more about the firmware.

Experimenting with feed rates and acceleration now, i hear differences in tone but not yet in loudness.
I must find some good info on these settings how they relate to the motors and how the 2 settings work together / against each other.
I hope i don't damage anything.
I'll try to get the neighbour interested in the future. He seems to be more 'traditional' and thus into beer and sunshine. :-)
Thanks for all the suggestions, i will try them all.
UPDATE!
Turns out to be all about energy absorption afterall.
I made a little gaffatape 'gasket' that i placed UNDER the z-axis stepper that made all the difference. This absorbs the vibrations before they go into the wood.

Neoprene is a good idea! For now i keep the hacked solution as i'm curious how the belt driven Z axis performs. I have the feeling that might be the best way to get rid of the noise.
Also 0.9 degree steppermotors are said to make less noise and have a bit more power.
I'm having a little break until the weather is a bit more humane. (its still 30C inside in the middle of the night) I'll also try to post some pictures of my Y axis hack.
