Topic: Davinci Sounds changed

Before I start, I'm fully aware that 3D printers make the stepper motor sounds. Musical to some wink

But since I've had the printed it started off sounding smooth but a bit more often now it has some almost vibration sounds mixed in? Is that just parts loosening up from being new? Or does something need adjusting/maintenance on these things? I've probably done around 50 hours of printing at a guess.

Anyone who can weigh in on this if its normal or needs a tweak, it would be massively appreciated.

Cheers!

Re: Davinci Sounds changed

Sound like a good ear . Not a davinci owner but  IMHO . Sounds like it is time to lubricate check /inspect  and adjust as needed. I will let tHe davinci guys fill in the details. Time for some good old PM. And normal to need a little attention.

Re: Davinci Sounds changed

When I removed my original extruder motor I found the screws had come loose so it might be worth checking when you next pop your hotend off.

Re: Davinci Sounds changed

Cheers for the replies people. I've not taken anything apart on this thing but I would say that they sounds are when its tracking along on the X/Y motions. Does this give any more info? Or would it help to capture a sound byte?

Re: Davinci Sounds changed

Check if your Y axis bushings are loose... I can hear vibration from them when the carriage is doing movement on the Y axis.

Re: Davinci Sounds changed

I have been having major vibration noises as well on my 1.0, I finally had enough today and decided to check the extruder as no matter what I have done with the x and y carriages, nothing changed, and what I found made me print one of these!

http://www.thingiverse.com/thing:623274

What I found was that the stamped steel fan mount only had one screw holding it on the extruder and the bottom of the mount had also been vibrating against the cold end heatsink.  I still have some vibration and will need to track that down, but at this point that only crops up when speeds get to 90 mm/s or higher which really is pushing the printer I think since stock I believe max is around 60 mm/s but I could be wrong.

Re: Davinci Sounds changed

Sorry for the delay.

I've captured a short section in the hope someone will be able to shed some light on this. There are a number of sounds.

There is a Background rattling sound - Almost like a screw coming loose?

I know the musical sound of the printers there as the steppers move but that sound was also less prominent when I got the printer so assuming some things are coming loose/worn in a bit/ slackened off?

Any help would be really appreciated because when the printers off i cant hear the sounds to spot it. not to mention i dont ahve a clue where to look really.

Thanks

Like it or not, these are machines and like any machine they need to be maintained. I would suggest getting the proper sized torx bit then popping of the side panels and getting in there and tighten every screw you can find. Then make sure the belts are tight. Then check that the bearing are all snug in their holders. Look up in the top front and back and locate the bearing holder on the sides of the machine. make sure they are not cracked or damaged.

This needs to be done about every three months or more depending on use for this machine as they used no method to lock any of the screws.

Re: Davinci Sounds changed

Thanks for the reply. Yea I understand they would need maintaining. It's just without knowing, a diagram/or photo where to look for those prime areas that need adjusting/maintaining.

I would say the main noise of one element if you are looking face on at the machine is the left to right travel. In 3D programs I use its X -Left to right, Z -is back and front and Y -is up down.

So it would be in the Left to right X axis. As when the machine moves more front to back there is not the Vibration.

Hate to be a pain but do you happen to have a quick (even rubbish photo) or the primary areas that generally need adjustments?

Thanks
Chris

Re: Davinci Sounds changed

Had a vibration sound since the day purchased. Especially at higher speeds doing an XY travel. Done everything imaginable to my printer.
Youtube videos will also expose the same sound. Im thinking now that the steppers have resonance sounds.
Like CNC microstepping, when not setup correctly.
As long as I get good prints, live w/ it.

Re: Davinci Sounds changed

I recently printed a couple of the stepper dampers on Thingiverse in ninjaflex.
It helped with the x axis motor but not so much with the y axis.
So I made a couple of pads in ninjaflex for the metal bracket which holds the y axis stepper.
The pads are 5mm thick and coupled with the damper on the stepper this has greatly reduced the vibration noise.
