I have just finished setting up my two X1CC’s on my new workbench. Currently each printer is sitting on a 16"x16" (40.64cm x 40.64cm) concrete paver and those pavers are sitting on a single sheet of 1" (2.54cm) thick polyurethane foam pad. One of the printers is sitting on the Anti-Vibration Feet from Bambu and the other one is using the stock pads. I have recalibrated both printers one at a time while the other one was turned off.
What I would like to do now is run a print that will show if I have any resonance issues due to this setup. I will run each print one at a time on each printer. Then I will run them at the same time on both printers. Hopefully that might be a good indication on how stable everything is. The question is, does anyone have any suggestions on a good test print out there in 3D Model land that I can use for this not so scientific test?
That is a tough question but sounds like you have done some stuff that might help out.
All my printers are on their own stand for this reason.
I guess print something that will get one printer shaking around then on the other printer run the klipper ringing test and see what happens before and after with two ring test to compare them.
Thanks @3DTech . I will run a test with that STL and settings your provided and share my results. My first test provided some results I weren’t expecting already. I downloaded the Android app “Vibrometer” (Vibration Meter - Apps on Google Play) and printed a simple 25.6x25.6x12mm cylinder with the word “TEST” enbedded into the side. I printed them one at a time while the other printer was turned off.
As shown below, the “Printer L1” with just the stock foot pads, caused a lot more vibrations than “Printer A1” which has the Anti-Vibration Feet installed. Yet, while visually watching the printers running, “Printer A1” was bouncing all over the place and “L1” barely moved. My phone was sitting directly on the foam pad in the middle of the printers and it wasn’t touching either of the concrete pavers.
My view is that for best results, you want the printer “coupled” to a heavy mass, which is why many of us put a concrete paver under the printer. Flexible feet may dampen vibration transmission to the surface, but they will allow the printer itself to move more, which you don’t want.
@holmes4 I understand what you’re saying, but don’t I need to come up with a “happy medium”, so the printer doesn’t shake too much AND doesn’t send too much vibration to the other printer on the same table. The pavers each printer is sitting on are 1 inch thick and weigh 36 pounds (16.33 Kgs).
I am running @3DTech test recommendation at the moment on each printer one at a time. I think the real test will be when I run them at the same time. Do you agree or is that not a good test?
The suggested test is OK by me. You could also experiment with sorbothane discs under the paver - I plan on doing that, though I don’t generally run more than one printer at a time.
@PrinterMcgee I’m in the same boat as you, in an apartment on the top floor with neighbors below. I’ve already asked them to let me know if they feel or hear any weird noises above their 2nd bedroom (which is what I use for my office in my apartment.)
By the way, that Vibrometer app I am using is super sensitive on my Android phone. I had one of my cockatiels walk around on the pad on the table and it even detected that. Each one weighs around 85 grams.
The Anti-Vibration Feet seem to dissipate the vibration of the printer from the table quite a bit. Once again, both prints turned out identical. (Escuse my horrible picture taking ability. A1 is slightly blurry.
Almost identical results from the test running L1 by itself. So far it is looking like 1 inch pavers with 1 inch polyurethane foam and the Bambu Anit-Vibration Feet are doing a great job. The prints are identical again and no different from the previously posted pictures.
NOTE: I am actually using 2-inch thick (5.08cm) pavers, not 1 inch like I kept saying previously. Sorry about that.
I ran several tests today on all kinds of prints, including @Jrock recommendation. No issues in any of them. All with the specs shown below, except I used PolyLite PLA Silk for part of Jrock’s test.
Both prints turned out identical with no defects of any kind. I bumped up both printers to “Sports” mode as shown below. I didn’t have the courage to go to “Ludicrous” mode.
I feel quite confident that this setup works very well in preventing excessive movement to each printer and to the table and ground. I will ask my downstairs neighbor tomorrow if he heard or felt anything but I am pretty sure the answer will be “No”.
By the way, for about 20 minutes of one test, I put my phone on the leg of the foot of the table right above the ground and the meter never went above 1.6. @PrinterMcgee I would say this is a winning combo to prevent your neighbors from murdering you. (Well, at least for this issue. )
@PrinterMcgee I was thinking about that and one thing I didn’t mention is the Anti-Vibration Feet from Bambu Lab are a pain in the butt to attach to the printers. As soon as you get 1 or 2 set correctly, they get all screwed up when you try to attach the other ones. I purposely didn’t use any adhesive with them because I plan on using your Super Feet tomorrow when those pads arrive from Amazon. I think your setup will be much easier to deal with than just the Bambu feet.
Will it lower the vibration even more? Who knows. But I will give it a go and let you know.
I tried printing them without supports like Bambu Studio recommended. They came out okay except for the fact that the bottom is somewhat bowed. When I got the pads from Amazon this morning I attached them to your feet and realized they won’t work because of the bowing. So I am printing them again with full supports.
By the way, except for the bowing issue, the pads fit perfectly into your feet.
By the way, if you pick up those same pavers, make sure to put the chamfer/bevel side down, otherwise your feet and the pads will not sit flush on the concrete.
but sounds like you have done some stuff that might help out.
