High Pitch static noise
Recently my printer has been making a wierd high pitch noise from the Einsy board whenever the motors have been used, it didn't do this before, and I've tried to look for reasons or solutions but haven't been able to find any, I would greatly appreciate some help so I don't get tinnitus from my printer.
When I turn on the printer there is no noise, but as soon as I do something that makes the motors move, like home it in this clip, it turns into high pitch static noise after its done, and it makes a weird tune down sound when turned off.
Sound: Prusa Noise
(apparently the embed didn't work)
I don't know how you embedded the sound file, It did get embedded but there were some formatting information embedded with the URL, which prevented the file from showing...
In the image above, you can see a copy of the original information, with the red lines denoting the un necessary formatting information.
the shorter line underneath is what I edited the link, to, so that it would work. (You are not the only person who has had this issue... Would you mind letting us know what operating system your computer is using as this may help the DEVS...)
I will link this post to the developers in the hopes that they can work out what is happening
regards Joan

Just wondering its definitly not comming from the psu. Does it do it on certian motors or all. Does it do it when preheating heatbed and nozzle?
Please help me out by downloading a model it's free and easy but really helps me out https://www.printables.com/@Hello_474427/models
RE:
No, the noise is 100% coming from the box with the Einsy in, I've tried putting my ear up and around to listen to the motors also, but its definitely the board.
It seems to be only the X and Y motors, haven't tried the E motor, but the Z motors don't seem to cause it to make noise. I also tried preheating the bed and nozzle but didn't make noise there either.
Also for the Edit to my post by Joan, I'm on a Windows 10 Desktop.

Thanks,
I have used win 10 on the last laptop, so that's probably not the cause.

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK
RE:
If it is coming from the controller board it could be coil whining or ceramic capacitors acting as tiny speakers due to the piezo effect when switching current. Use tygon flexible tubing with one end at your ear and the other to scan and isolate precisely where the noise comes from. You may have to remove the cover to expose the board and isolate the precise part.
Ceramic caps are notorious for that. Coils usually have varnish or are potted but with age the individual windings can break free. The magnetic force generated by the current will rattle them with the same frequency.
The cure is usualy a generous dap of silicon RTV on the ofending part or changing it altogether.
