Ticking noise at low speeds

Hallo,

I assembled my MK3s+ kit and it prints fine.

I noticed that during the first layer, at lower speeds there is a "ticking noise".

The noise disappears, or at least I cannot hear it anymore at higher speeds

can it be that the x or y belt is too tight?

 

.

 

PS: I added a link to a dropbox file with a video, not sure if that works. I was not able to add a video to this post.

RE: Ticking noise at low speeds

Your video doesn't play.  Try posting it to youtube and then a link to it from here. 

 

What is the source of your ticking sound?

RE: Ticking noise at low speeds

If the ticking is caused by the XY belts, I'd expect it to occur when not extruding.

Do you hear it when just moving the nozzle around without extruding? IME, ticking is caused by back pressure in the extruder.

  • If everything has been fine previously, a partial clog is a likely culprit. Read up on doing some cold pulls to clear the hotend and nozzle of debris. I do cold pulls whenever swapping nozzles and often when switching from higher-temp filament to lower-temp stuff.
  • Adding 5C or so of heat can help when some filaments start causing ticking, though this can contribute to stringing.
  • Ticking can also indicate you're over-running your hotend capacity. This will occur at areas with higher speeds though (e.g. when printing infill) and simply backing speeds off can help.

@dimprov

I don't know the source, I cannot locate it. 

My suspicion is the belt from the Y Movement. I was wondering if someone else had the same experience.

maybe this link works https://www.dropbox.com/s/rqdgjzbtlspt0fu/img_2180.mp4?dl=0

I listen to the video, it sounds like the belt might be to tight.

Thanks for the suggestion, I will loosen it tomorrow, and let you know.

I'm guessing partially clogged extruder, like what Muppet Labs said.  Here's a way to test that hypothesis: disable filament detection, unload the filament, and then run the same gcode so that you're air printing.  If you still get the same sound, then it's something else.

I will check it, thanks for the suggestion.

The print however is perfect. I would expect that a partially clogged extruder is visible in the print with under-extrusion.

In the video his extruder is laying down a beautiful first layer, it doesn't appear to be clogged or under extruding.

By the way, how did you get your MK3S+ so quickly?  I thought that the MK3S+ was only just very recently announced about a week ago or so.

Some were sent out before the announcement.

I had ordered a MK3S. Delivery time 1-2 weeks. I received the MK3S+. very happy.

I released the tension of the Y-belt a bit.

The ticking stopped, so that was successful.

I am still worrying a bit about the Y-stepper motor pulley.

The belt is all the way at one side of the pulley (see picture) touching the flange. I cannot change it. I cannot move the pulley on the motor axis more, I already have a minimal distance of the pulley to the motor. Also the belt is all the way in on the holding mechanism of the bed. 

Maybe this is not a problem, maybe this was causing the ticking sound in combination with the tension.

RE: Ticking noise at low speeds

Mine have been like that, on my older MK3 units for almost 3 years now and neither has had an issue to date. I was a bit paranoid about it and ordered an extra belt to replace it, in case it abraded. I still have the new belt in the bag and I still keep an eye on it but nothings happened.

I can actually walked them back over by applying gentle pressure to them top to bottom while slowly moving the carriage back and forth, but they always seem to end up back there when I'm not lookin. at this point I just figure it's their home.

Thanks for the answer, I will not worry anymore.

I also must say the print quality of this printer is way better then my previous Davinci Pro.

RE: Ticking noise at low speeds

Yes, I have to agree the print quality is very good, as I mentioned I have a total of three of these machines and I'm not disappointed in any of them. like you I most recently purchased an MK3S just a couple months ago. They are work horses, theirs been times they were rode hard and put away wet, and they keep on going.

I do regular maintenance, but the print quality is as good on my oldest machine as it is on my new one.

Now that it's working, you can measure the tension with this https://www.thingiverse.com/thing:2230598

and then you'll have a reference you can use in the future to repeat the same tensioning level, without having to guess.  😀

What does your Mk3s+ report as the belt tension?

I checked under Support > Belt

It tells me:

X 266

Y 283

I have no idea what it means and what and how it is measured.
