Vibration dampers? Hey, For some times I have been wanting to make some vibration dampers for my printers but have kept putting it off... On slow printers it doesn't matter but on my new printer it does as it can print relatively fast (I am maxing out the RAMPS/Arduino processing power @16 microsteps so how fast it actually is, I have no idea). Now the printer stands on bubble plastic (yes) and as ridiculous as it sounds, it works really well for vibration absorption. But as forum readers may know, I am planning to make a heated enclosure and for that I need to wrap up the actual printer design... So that's the back-story, now: Anybody has any solid experience with vibration dampers? Or what do people do? Looking around photos I seem to have found a little of everything. Some just use normal table feet of the kind you can screw up and down to adjust, some put the extrusion on the table and done. The cool industrial solution is to get something like this: 34-16052012-077149L.gif mod_embed_images_loadimage('57ce15a7a6d92e4264bafb381f318986', '/forum/thumbcache/0da/abc/16b/ded/3fd/cf7/c6b/474/6e2/1cc/02_800x400.gif', 'http://www.tracepartsonline.net/PartsDefs/Production/GANTER/34-16052012-077149/pictures/34-16052012-077149L.gif', 'https://reprap.org/forum/addon.php?397,module=embed_images,check_scaling=1,url=http%3A%2F%2Fwww.tracepartsonline.net%2FPartsDefs%2FProduction%2FGANTER%2F34-16052012-077149%2Fpictures%2F34-16052012-077149L.gif', '', 596521, 800, 400, 'Loading image ...', false); And this is maybe also what I plan on designing but just wanted to ask here before trying to re-invent anything...

... in Marin4Due I have something like 3000 acceleration and 20 jerk on a much 'stiffer' system with 400mm/s what's performing pretty well ... was much slower when tested on a Mendel-frame.

For damping fast moving systems you'll need more mass in the frames ... for damping foot fall sound (for ultra precise moving) I used big/hards resin-dampers on the floor, a steel frame on them, medium-soft dampers on the frame, a granite-table on them, a dish with some Ferro-Fluid in it and NdFeB-magnets under the frame of the mechanic, sitting in this dish ... was even better, than an active pneumatic damper for >10k€ ;)

Riiiight, lets say I want something in between that and what Edvardas posted - Maybe slightly more in the direction of that printed suspension Edvardas had ;)

No movie tonight of it, will see tomorrow. Thank you for all the inputs thus far.]]> LarsK CoreXY Machines Mon, 14 Dec 2015 19:27:16 -0500 https://reprap.org/forum/read.php?397,596521,596775#msg-596775 Re: Vibration dampers? https://reprap.org/forum/read.php?397,596521,596775#msg-596775

Woa, floating printer. That sounds pretty awesome - But I can only imagine that the entire printer starts oscillating after some time? The same reason why you want both dampeners and springs in a system.


You are all talking about noise, but part of my motivation is the vibration from the sharp accelerations(?) To me it seems like the sharp stops are getting reflected back and forth in the structure because there is an imperfect contact with the table. The result is that my printed edges comes out unacceptable at very high speed (~150 to 200 ish I think is the real speed).

I will shoot a video to show it.

@Edvardas - You talk about Springy feets ? Is that a reference to some particular model or method or is it just that it stands on springs?]]> LarsK CoreXY Machines Mon, 14 Dec 2015 14:15:21 -0500 https://reprap.org/forum/read.php?397,596521,596536#msg-596536 Re: Vibration dampers? https://reprap.org/forum/read.php?397,596521,596536#msg-596536
Also, switching to 24V apparently also reduces noise, but I have not seen a comparison yet though...]]> gmh39 CoreXY Machines Mon, 14 Dec 2015 08:47:28 -0500 https://reprap.org/forum/read.php?397,596521,596535#msg-596535 Re: Vibration dampers? https://reprap.org/forum/read.php?397,596521,596535#msg-596535
Instead of making this mods, you can remove most of the vibrations made by the printer upgrading the steppers to 1/128. these steppers will remove almost all vibration and there is no need of this type of dampers.]]> filipeCampos CoreXY Machines Mon, 14 Dec 2015 08:44:42 -0500 https://reprap.org/forum/read.php?397,596521,596524#msg-596524 Re: Vibration dampers? https://reprap.org/forum/read.php?397,596521,596524#msg-596524 My corexy made of 2020 profiles sits on a metal cabinet and is really silent. I think its because of the TMC2100 stepper drivers that drive X and Y axis.]]> Edvardas CoreXY Machines Mon, 14 Dec 2015 08:01:43 -0500 https://reprap.org/forum/read.php?397,596521,596521#msg-596521 Vibration dampers? https://reprap.org/forum/read.php?397,596521,596521#msg-596521
