to damp the vibrations of my printer I designed and made ​​of ABS a presser foot up two neodymium magnets in opposition.
Most are big magnets greater is the force that opposes the weight of the structure.
my printer that exceeds 30Kg I used two cylindrical magnets from 18x5 mm, but are just enough

Nice use of the threads library :)

Neat idea!

The magnets would definitely help separate the printer from the table top, but it's not going to convert much of the energy down to heat.

For silently dumping vibrations down to heat, I've been very happy with the (overkill) set of 2" sorbothane hemispheres I bought through amazon. The funny thing is, I've been so lazy that I haven't even attached them properly, so they're sitting on the bottom of some bench-cookies, thus actually allowing the printer to slightly roll on them and freely sway side to side (but still with generous energy-waste do to adhesion to the workbench).

One of these days I'll actually print out some proper mounts for the feet, but I'm curious if that'll make them more or less effective than the silly setup they're in right now. :P

yes thank you, maybe you're right
