Is there a reason why I'm suddenly getting ripples in my print?

    A1
  • Slicer settings used
    I’m using a .4mm nozzle with a profile provided by Overture.
  • Type of filament used
    Overture silk pla gold
  • Photos that clearly show the problem
    The objects on the left were printed after lunch. The ones on the right were printed before lunch.

Some obvious things to consider or rule out.

  • Your filament may require drying. This can happen even after periods of good quality.
  • Has the printer moved at all? You may be experiencing more motion during printing.
  • Have you lubricated the y-axis recently?
  • Have you tried a different filament?
  • Is the filament spool catching in the edges as it is being rotated?

Maybe too many carbs at lunch?

Could be a partial nozzle clog, try switching up the nozzle…or manually purge the hell out of it.

Did anything change between before and after lunch? Temperature in the room, humidity? Maybe a fan was activated? Was there a filament change between before/after?

The same thing happens to me, did you manage to solve it?

The surface that was ‘rippling’ was quite thin so I thickened it up. I think i might have been the infill showing through???. Also moved the printer a more solid table.

Hi, I found the following solution and it worked for me. In the quality - Advanced section, I activated “Smooth Speed discontinuity area” and lowered the “Smooth ciefficient” to 0.1. I also went down in the Speed Box - Acceleration “Outer Wall” to a lower rank. I hope this helps you too.
