Very likely due to the extrusion subsystem. Ultimaker uses 2.85 mm filament so filament motion is critical: a little slippage causes visible changes in the extrusion. If the teeth are worn out, this is the case. Worn out bearings (or dirty bearings) can also cause the same, since motion is not smooth.

@nowox That are worn bushings/rods as far as I can tell.It doesn't show the inside of the extruder so hard to tell if there might be other worn parts.

@0scar I've added a picture of what quality I am expecting. If it's not ringing I don't know how you call this default where the surface is rippled.

Is this old filament? My Ultimaker prints like the bottom. What material, what settings, see e.g. ["Help us help you!"](https://3dprinting.meta.stackexchange.com/questions/395/helpful-templates-help-us-help-you)>

The filament is not that old. I am sure it is caused by some vibrations somewhere.

Possibly a dumb question but the ringing is occurring on all 3 Ultimakers, correct? Possibly this has to do with a slicer setting that the Prusa can handle better then the Ultimaker printers (or an update to your slicing software).

@Dr.MantisTobbogan I don’t think it is the slicer’s fault. These machines are old and perhaps some components are causing this behavior

Okay, your call, just odd that all three machines developed a similar problem. I'm not sure how your Ultimakers are constructed but perhaps there are some rubber dampers that have dried out and aren't functioning optimally. Just throwing ideas out there really though...

@Dr.MantisTobbogan Actually that speaks of similar use: if 10 cars show the same behavior after the same distance, it might be the wear of the same part or a flaw in the design.

@Dr.MantisTobbogan You do need to do some maintenance occasionally by lubing the steel rods, lube is supplied with the Ultimaker. An Ultimaker 3E at work had a worn bearing bushing, I think they haven't properly lubed the rods.

Ringing with Ultimakers, what is the cause?

# Ringing with Ultimakers, what is the cause?

(Asked by: username_0 on 2020-07-14)

At my work, we have 3x Ultimaker 2+, 1x Ultimaker 3 and 1x PRUSA i3 mk3s. The Ultimakers have been used quite a lot for the past three years, but the belts and bearings seem ok.

I got heavy ringing with all Ultimakers, but the print on the PRUSA is neat even at a higher speed.

I have a Ultimaker 2+ which I use together with CURA. I print in PLA at 210°C. The print bed is set to 60 °C. I use a print cooling fan at 60 %. The layer height I set to 0.2 mm, the line width 0.8 from the 0.4 mm nozzle. The Printing Speed is set to 30 mm/s for walls and 50 mm/s for infill.

Is this a known issue with Ultimakers?

How can I fix it?
