UMS5 vibration dampener

Recommended Posts

The vibration is typically more with the belts and head.  I don't think those dampeners will help much unless you have 2 UMS5s on the same table.  You could put the printer on a folded towel.

 

Beware that if things are too slippery the printer can slide (slowly over a few hours) right off a table and "suicide".

Makes sense. We recently (~two months ago) tightned the belts, but should check it again probably.

If you want dampers, I would recommend using professional and tested damper mats, of which the damping specs are listed. Each material has a resonance frequency, also dampers, in which they absorb less energy. A wrong "damper" could cause the opposite effect: the thing getting into resonance, like on a spring. So I wouldn't trust a spring-like design like that.

 

Such damping mats should also be antislip, as gr5 says, so the printer can not vibrate off the table (we have seen a couple of these here on the forum...)

 

In the early days of harddisks (late 1980's) I have seen harddisks crash *because* they were mounted on dampers: the at that time very heavy heads swinging around caused resonance. We had to mount the disks directly and firmly on the metal frame.

 

If the effect you notice is "ringing" after a 90° corner in a print, this is due to the head changing direction suddenly. It won't help putting a damper under the printer. Then a solution could be to tighten the mechanical tolerances of the rods and bearings, and mounting the steppers directly on the driving rods, instead of via belts, I think?
