Ringing on single wall print

[johna 0]

Was printing this single wall last night, and it just seemed like the ringing was really, really pronounced:

It wasn't particularly fast (unless I messed up a setting....) but it seemed excessive. Anyone else having similar results?

what speed did you print ?

did you have the cooling fans on fully ? maybe the vibration of the fans could have added this wobble to the surface.

I'm not convinced all of that is due to ringing. Could some of those artifacts be part of the actual model?

To try and reduce ringing it seems that acceleration is the biggest culprit:

Model is from here, I don't think it's got any of that as part of the model?

Nope, that looks surprisingly smooth coming from OpenSCAD, I'm used to seeing all kinds of faceting on those models.

In that case I would look at slowing down the print and lowering acceleration as mentioned in the post I linked to.

Don't slow it down! Just reduce acceleration.

Here are the results of someone's experiment - only lowering acceleration helped - consider 1000mm/sec - posting #8:

HOWEVER, looking at his pictures and your picture they look quite a bit different. I'm not convinced that is ringing.

It's official, that's the first time gr5 has NOT recommended to slow down :eek: Also, I already linked that post

The size of the artifacts is what threw me off as well but I figured if he slowed down and reduced acceleration we would remove those variables.

:lol: :lol:

 

educed acceleration we would remove those variables.

 

Yes.
