Where does your printer stand?

This is the Ikea Platsa cabinet. The cabinets are screwed to the wall. Until now I have not done this yet. But I have a 2 cm thick granite plate under the printer, which seems to have enough mass to dampen the vibrations a lot. In general, the printer is already much quieter in the cabinet. You can only hear the chamber fan in the next room. The mechanics can hardly be heard anymore.

Guys, Friends, 3d Printing Countrymen, Lend me your ears!

You donā€™t need to absorb vibrations. Thereā€™s a rumour going around that you have to go by 70 pound concrete pavers to put your printer onā€¦ This is simply not required. In fact, in my opinion, I think itā€™s harmful. Not allowing your printer to vibrate will cause more damage in the long run.

I put mine on a wheelie stand like this, and when it shakes back-and-forth it cancels out its own vibration.
The high tolerance for movement actually compensates for the travel moves.

Trust me, it works. Amazing. Hereā€™s a picture of one of my prince and hereā€™s a picture of my set up.

Embrace the vibration!!! Just make sure you do a calibration every time you move the printer to a new location.

Why would that be so?

I donā€™t think it applies to forces within an object. When a motor rapidly moves the print head in one direction, the whole printer wants to move in the opposite direction. Whether the printer is solidly anchored or floating does not change the amount of force and stress generated within.

Punching yourself in the face will hurt whether youā€™re wearing ice skates or football cleats.

I had a long reply here, but I decided to edit this post.

My long reply had a very long and complicated example, but I thought of an easier one.

Forget about punching yourself in the faceā€¦ How to use a more real world example, letā€™s talk about buildings designed to withstand earthquakes.

Same concept. The building floats. There are different mechanisms to make this happen, but generally speaking, the building is floating on itā€™s on suspension system. When an earthquake hits the building in the ground or separated, so when the ground shakes, the building is cushion from the back-and-forth shaking motion. This is the same concept Iā€™m using in my set up. Hello, my printer is not actually floating above the table on a suspension system, there is a half an inch in either direction of play, and the table is on wheels. Basically cushioning emotion, and allowing the table to move with the printer ever so slightly.

I hope this makes sense.

I can only recommend you to get familiar with CoreXY motion system and resonance compensation.
It will be a great ā€œlesson learnedā€.

Sure thanks for the advice. Youā€™re obviously super smart when it comes to this stuff. I can tell because of how condescending you are.

My results donā€™t lie. My opinion still stands firm.

But then donā€™t breach others with an opinion, which is based on years of testing of the CoreXY and real measured resonance data just wrong.
Have a good one. :slight_smile:

Except most of us using pavers arenā€™t using them to make a completely rigid surface. Thatā€™s why we have something underneath the paver to dampen the vibrations the printer is making. Most use foam. I use sorbothane hemispheres.

The printerā€™s stepper motors vibrate at a high frequency, especially on the Bambu Lab printers because of the speed they can move at. The acceleration of the tool head creates additional vibrations. These vibrations make a lot of noise. The vibrations then transfer to the the rest of the printerā€™s parts like the frame and the metal panels, which creates more vibrations and noise. The table that the printer is on will resonate these vibrations and create additional vibrations and noise, almost acting like an amplifier.

Those point of the paver is to have a nice, large, flat surface area for the printer to sit on. But the key is whatā€™s underneath the paver, which decouples the printer from the table. The foam absorbs the vibrations and releases them in kinetic energy (heat). This essentially removes a lot of the vibrations from the system, but still allowing for the printer to move as a whole unit at high speeds.

So those of us with pavers and foam are kinda doing what your table is doing, weā€™re just doing it much, much more efficiently, with less noise, and probably with better print quality.

So Iā€™m not disagreeing with your train of thought. Your thought process is headed in the right direction, itā€™s just poorly executed. Core XY is doing more legwork than it needs to with your setup.

Had to build a tiny maker space for myself, table is made out of 5/8 plywood and secured to the back wall and the adjoining table but that is it.

That does help! :slightly_smiling_face:

I went with a slightly more evolved version - I have two IKEA LACK table on top of each other. I printed brackets like the ones in the top post and screwed the legs and top to make it more solid.

On the bottom of each table I put a $3 concrete paver stone (12x12 inch) held with construction adhesive and 4 screws, left upside down for 24 hrs to set.

Finally I put washing machine pads under the feet so the whole thing can move slightly. I used these:

https://www.amazon.com/gp/product/B08HVNP45W
The result is a very quiet and stable base that also has some freedom for movement. Works great, much better than I expected.

I have a CR-10S that I had on a heavy duty rolling cart like some have enthusiastically endorsed. It had a bunch vibration problems. A stable but cushioned base is much better. Been there, done that, it failed to work anywhere near as well.

If you look on YT for CNC Kitchen he did a bunch of engineering tests instead of ā€˜opinionā€™ and he reached a similar conclusion.

Yourā€™s helps, but for a few dollars and a bit of time can be even better! :wink:
Cheers!

I like your reply. Youā€™re basically agreeing with me from the perspective of the concept but you donā€™t like my execution. I can appreciate that. Actually, thanks for showing me those hemispheresā€¦ I will have a look. Iā€™m not a big fan of bringing a concrete block into my house but I am open to other options.

My current set up is working fine. The only aspect of what you said that I didnā€™t think of is that, although my current set up is dampening vibrations it might be dampening too much and causing the motors to work a little harder than they need to. Iā€™m not sure how I would prove or disprove the theory but itā€™s good to think about.

So far for the last three weeks everythingā€™s been smooth as silk and my prints have been coming out great but thereā€™s always room for improvement.

Sir, Iā€™m not breaching anyoneā€™s opinion I am simply offering my own. If you could show me where the years of CoreXY data is that you are referring to I would be more than happy to review itā€¦ And donā€™t tell me itā€™s on the Internet. lol. Please be specific.

And just for some background, Iā€™d like you to know that Iā€™ve been using a fusion3 F410 for the last six years at work. Iā€™m pretty familiar with the technology.

Iā€™m not trying to be a pain in the ass, but this is a forum and the whole point of a forum is for users to exchange ideas.

I am open to suggestions and new ideas.

Have a great day!

Oh, absolutely not, me either! There was never any question in my mind. Weā€™re all here learning from each other, eh? I try my best to be nice even when disagreeing. Sometimes text doesnā€™t come across right and translation to other languages is even worse! Overall this place is pretty friendly.

You want wild jacka$$es attacking you? Pop over to FaceLess or Discord and post something controversial. LOL

I was pretty specific - CNC Kitchen on Youtube. Iā€™ll find the exact link since Iā€™m a nice guy. He did two - 1st six years ago (!) 2nd a couple years ago -

Those are not the only ā€˜engineerā€™ looks at the issue, thereā€™s a lot more.

But this is a controversial subject with many opinions of varying skill and training levels espousing their firmly held opinions. Being open to learning from others is the sure sign of a scientific mind ā€¦ IMHO :stuck_out_tongue_winking_eye: :grin:

Like I said ā€¦

My solution is the same principle executed more elegantly since I hid the blocks below the table so they donā€™t show, then did the vibration pads on the whole table, but it does the same thing as CNC Kitchenā€™s approach, just a bit classier.

I also donā€™t skin my knuckles on the concrete ā€¦ :rofl:

Ummm thanks for the dataā€¦

But I was replying to rovsterā€¦

The way to settle this is objectively by a simple experiment. What is a model thatā€™s highly susceptible to X1C printer vibration, such that it is shown in the final print? Print it without the paver and then print it with the paver (with or without an underlayment of some kind). Compare results. I think CNC Kitchen has already done this and found benefit on a Prusa printer, butā€“who knows?-- maybe the results will differ on an X1C.

Okey. Nevermind. :slight_smile:

Very hard to say how impactful it is on a X1C, since we donā€™t have access to the tested resonance data.
So we canā€™t inspect the curves at which frequencies of resonance the printer is having a hard time and will impact the print-quality.

But produced data by other CoreXY based printers, show that any low-frequency resonance has quite a bit impact on the print quality. Here is a good example of VZBot, comparison of a rigid mounted printer vs not mounted: https://www.youtube.com/watch?v=86SfLaKpROU (Actually proves the cool theory of sfazzina wrong :slight_smile: )

Personal opinion but I doubt it. Core XY vs Cartesian but vibration is vibration. BL at least has Vibration Damping.

On my CR-10S I spent literally years modding and tuning it. One thing I did was upgrade the electronics to a Duet motherboard which supports dampening. It did help, but getting off that cart helped a lot more.

Apparently many people offering the same opinion no matter the amount of experience, evidence, or logic will fail to convince some people.

Classic you do you. :grin:

Guys, maybe no one is wrong and no one is rightā€¦ lol.
Logically speakingā€¦I am getting great results so I know my method isnā€™t wrongā€¦

I agree we should all just agree to disagree.

btwā€¦I like the reply from ThanksForAskingā€¦

Lots of good info there.

Have a great day all. Ciao
