Help me make this thing quieter.

This is on the folgertech 2020 i3

I am trying to eliminate the Y axis vibrating noise that I am getting. It is the same noise the person who posted this youtube video is having. [www.youtube.com]

I can't replicate it by using the manual controls in Repetier it seems to depend on the speed the bed is moving. I have tried using the dry run feature in Repetier but it doesn't work for me.

Any troubleshooting ideas would be great or if you know what it is that would be even better.

Judging from the noise it made, it seems like the rails are somewhat loose, making it vibrate

The Y axis smooth rods are tight in the blocks on the frame.

It also seems like it gets worse after it has been printing for awhile.

What about swapping the motor to another axis?

Also the pot current and motor temp during the run?

The Y motor is actually larger than the others so I can't try to swap them. I have been printing for about 5 hours and the Y motor is still cold.

Try increase the motor current on step stick pot, let it somewhat warm to touch, if you have something to measure the temp, let it be around 30'c

How would this help against the noise?

The rattling sound is clearly a sign of cheap linear bearings. You can try to use grease instead of oil on the rods ( better: IN the bearings ) or buy better bearings.

I found last night after my print was done when the bed was still hot if I slowly slid the bed by pushing in the front edge center I got the noise. I am going to try some grease in the bearings and maybe some kind of pad between the bearing blocks and the metal bed.

Any recommendations for grease?

I tried some grease in the bearings and that didn't get rid of the noise I used Krytox because I had some. It doesn't happen until after it has been printing a while so it has to be something changing with the heat right?

That´s why I like the classic prusa threaded rod y-carrier better. The threaded- and smooth rods are both steel with the same temp-coefficient.
No misalignment from different temp- expansion.
You can try to loosen the clamps on one side of the smooth rods. So they can float axially instead of deforming the hole frame.

at about 4:30 he starts talking about resonance... could be the problem. I have the folger tech 2020 as well and I also get the Y axis noise. In my limited testing I've found the noise to be dependent on the shape of the print and the speed. You can't really change the shape of the print, but I have found that lowering the speed or feed rate, usually helps.

My Y axis is the quietest on my Folger 2020. My x-axis however....... sounds exactly like that video. And to be honest, I think its cheap bearings and or an alignment issue. It gets louder with resonance, but is still there the whole time regardless. I have tried everything short of replacing the bearings. I thought about bushings, but mine has gotten a lot quieter with time, so it doesnt bother me much anymore.

Also my Y motor is ice cold, even after 14+ hours of printing. So I don't think that the motor has much to do with it. I just think these bearings are super cheap with poor tolerances allowing them to rattle. If anybody has made the switch to bushings please chime in. I haven't decided if I want to or not yet.

I am starting to think maybe it's so loud because it's being amplified from the table. I tried placing the printer on a carpet tile with attached pad and that made no difference but it's not a very thick pad.

My behaves exactly the same way. I found one thing that was vibrating was the left vertical smooth rod in the motor holder at the top. If I jammed it in there or held it, most of the noise went away. I haven't gone looking for a solution since it doesn't seem to affect anything (except my nerves).

Had the same thing on the right smooth rod. I also think my X axis got quieter after some use. I now just want to get rid of the Y axis vibration and replace the PSU fan with a quieter one.

Do you think it would be worth printing some plastic bushings to try?

I also had a lot of Y axis noise. I was thinking of plastic bearings, and printed several designs, but all of them had high static friction. That is, when I applied a force to them they stuck then suddenly moved. I was doing this by hand with them on a spare piece of chrome rod, so it might not be an issue when driven by a motor.

I started to take apart the Y assembly to replace the bearings with some new LM8UUs, and in doing so found that the bearing mounts were not completely tight. The nylock nuts were apparentlyt right, but were actually in some cases as 1mm down the M3 screw away from the mount. When I tightened it up, most of the noise went away. It was mostly the aluminum plate vibrating and sounded very like that video. There is still a little noise on very slow and very fast long Y moves probably from a bad bearing, but the nasty resonance as in the video has gone away. I used to notice it most on 45% infills, and now no longer get this.

I got a 1/4" thick silicone pad at a surplus store today and put a 4"x6" piece under each corner and that has made the printer quieter. I took them out during a print and it got much louder. I don't know about the rattle noise that I started the tread about I didn't hear that with or without the pads today yet. I wonder if a big pad under the whole machine would be better or worse?

I pulled out the fan from the power supply and it's 60mm x 16mm and it's a two wire one but it says that it's 16v on the tag? What can I do to get a quieter fan in there? I could just get an ATX power supply I guess but it wouldn't really fit on there nice like this one does. I suppose I could just wire a 12v one to the 12v output on the power supply but then the power supply couldn't control the speed.

I am seeing threads about using an xbox 360 psu is that really enough power?

I got a 60 mm fan and ran it off the 12v out on the PSU it was as loud as the one in there already. How much output do I need to run this machine? I am thinking I will just get a passively cooled PSU but the largest I can find is 20A.

I now think the vibration noise I am getting is from only using one bearing on one side of the Y axis. I printed another bearing holder and drilled some more holes in the bed plate so I could attach 4 holders to the plate. After doing this I do not get the noise but I did not get the holes located perfectly.

Has anyone found a good printable Y carriage or a plate I can buy that will accept 4 bearings? I see many printable ones but an not sure if they would be good.

I got a badly drilled acrylic y-frog with my sintron i3 kit. I had to drill the holes 4mm wide to make it run smoothly. I used washers and nyloc nuts to fix the bearings, once aligned.

I'm having same kind of noise from my extruder. If I connect it to the pins of another axis, it runs smoothly, without problems, but on the pins of E0 it trembles a lot, what's causing this noise, and worse, ribbled innacurate prints. I'm starting to think perhaps my stepper skips some steps (problem on the ramps board?) I can eleminate bad wiring and bad stepper/extruder because it works fine on other axis.
