I have a new setup I quite like but from the previous one I had, it has a vibration issue.
Specifically in the left to right direction. I am fixed in 6 points on the back wall.
I know the shelf (Ikea IVAR) is light compared to what I had. Should I stiffen it? Increase the weight? Fix on the left? Isolate the shelf?
My civil engineer mind tells me to brace/ isolate but the how is unclear.
Throw a concrete paver under the printer
That’s the thing, I am not sure the shelf can take that weight…
Usually, it is best to address vibrations as close to the source as possible. So the usual paver + foam of course comes to mind.
On my X1, I have great success with the HULA’s although I reduced the z-“Dampeners” to two layers for them to work properly. Also, I feel that the spring stiffness is not tuned to the Eigenfrequencies which may explain why I have seen comments of them not working as well on the A1 series.
Just note that vibration isolators will reduce the transmitted vibration, i.e. the printer will dance around more on top of the isolators.
You could frame the underneath of the shelves so its more like a table with something to sit on , although not being an engineer i dont know if will help alleviate vibration , mine sit on a steel framed table and i still get some vibration
mainly from a print set up and a little creeping during printing
My guess without seeing anything other than photos posted is that you need a couple cross bars in the back to help stabilize swaying left to right.
Open backed shelves usually require addition support since there is no backing to be that support.
A couple diagonal supports across the back should help a lot.
Edit: This is kind of what I am referring to.
Ya I can install them but I thought that my rigid anchor at the back where enough
Are we talking about shaking or vibrations?
Aren’t they the same? the vibrations from the travel of the plate induce shaking to the shelf?
I think that is way too wobbly. Those should be 2x4 and cross reinforced to make a “workbench” level desk or shelving as if you were going to sit a table saw on it and trust your life with that saw running…I…wouldn’t on that haha.
Instead of explaining the setup I’ll just tell you the best setup ever. you go buy a huge slab of granite or marble and sit the printer on that. The end. But none of us have 4 ton chain hoists in our living rooms, so next best is a huge rock. no giant rock? ok, stacked 16x16 patio pavers, that kind of thing alone (go to the dollar store and get those anti-skid rubber hole matt rolls for lining and your spoons dont fly everywhere? place that between the bricks when stacking), again most of us cant do this putting 20 bricks in our living rooms I get it, so → down the weight line you go…heavy furniture like a 200lb+ desk, the single paver underneath yada yada… until you eventually reach…your wickity wobbly setup above. haha
I am not typing above to insult, honestly. Just how i statically look at the scale of how far off you are and where you need to be. hehe
To explain -why- and not leave you hanging, all movement = vibrations. and sadly these new printers move so damn fast it translates to directly moving the surface they are on if not 2-3-4 times the entire weight of the setup TO not be able to be moved type thing. The weight just eats and kills any possible vibrations IE: granite slab. On your setup above I predict the speed will shuffle down the legs and “walk” your entire desk - yeah! - left and right -a hair- and juuust enough to drive you insane with banding and ghosting. 
I’ll cleanup and add my own setup pic tomorrow, but I would get some much heavier legs on that thing to start for sure, and at least 1 patio paver stone (they cost 2.50) and a rubber something under to make sure it sits put. I bet this will add weight on those legs tho and cause vibrations still if not secured =/
catch you tomorrow!
