Very loud noise and bad vibrations on Z-Axis  

Re: Very loud noise and bad vibrations on Z-Axis

same here since the last firmware.
with older firmware i dont have this problem

Re: Very loud noise and bad vibrations on Z-Axis

ok, interesting.
But i did not do any update.

Re: Very loud noise and bad vibrations on Z-Axis

Same here, been there since day 1. I can mitigate it to a large extent if I squirt some oil into the Z-axis bearings. I think that reduces the vibrations that makes something else resonate but haven't found out what part exactly.

Re: Very loud noise and bad vibrations on Z-Axis

I also tried some oil but without success! Nothing changed.

Is that not the PSU rattling?

Re: Very loud noise and bad vibrations on Z-Axis

no, i think it is not the PSU rattling. It comes from the z- spindles.
But this was not on my first 2 prints. There was everything ok.
But at the third print this problems come. In printing mode you don´t hear that noise. Only when you move fast. (for example: during calibration)
And you can feel the mechanic vibrations.

The PSU rattle is well documented.. Its caused by a plastic sheet of insulating material which rattles at certain frequencies.

Some people have poked things through the grill to secure it.. I am personally going to open up my PSU and "stick" it to the case so it doesn't rattle.

Re: Very loud noise and bad vibrations on Z-Axis

But when i move z-axis up it makes a horrible noise and the printer is vibrating very strong.
When i move down it is even worse. Something is wrong.

Loosen the screws that hold the Trapezoid nut.
If tightened too tight, the nuts may be slightly skewed to the motor shaft and you will have that sound.

Re: Very loud noise and bad vibrations on Z-Axis

ok, thank you for that hint! That sounds logical.
I will try it when i am at home in the evening.

Re: Very loud noise and bad vibrations on Z-Axis

I had this for a while... The issue for me was that the printed plastic cover for the LCD was loose, just press the front to clip it back on.

I also released why this was happening, I was not pressing the button but pinching it with one finger behind the cover. So occasionally I had been losing the cover off and allowing this to vibrate, but it was always worst during mesh bed calibration.

Maybe you should try this too.

Thanks. That fixed my loud Z.
