Diagonal wavy arifacts
Hi everyone,
This is not a first print issue, but an issue that has developed with our Core One. All prints, regardless of material, have these diagnoal wavy artefacts on the perimeters. They are easy to see and feel. This print is in Prusament Pritine White PLA. The printer is running 6.4.0 and the model was sliced using the 0.10mm fast detail setting in PrusaSlicer 2.9.4. The print did not complete due to bed adhesion issues, but it still illustrates the artifact problem
Has anyone seen this issue before on the Core One, and what can be done to recitfy it?
Thank you!

The boat on the right was printed on a MK3 using the same filament and the 0.10 mm detail preset, the quality is much better
I also tried printing cubes on the Core One with a single perimeter, the cube on the left used the 0.2 mm structural profile, and looks under extruded. The cube on the right used the 0.10mm fast detail profile, and looks under extruded, but also has the wavy artefacts again
RE:
Have you done gantry alignment and belt tuning? The more information you provide, the more ideas people might come up with.
Eyeballing the pattern, it could be possible that it's related to one of the two motors (depending on print orientation: One axis ripples, the other axis adds offset, that is, shifts the pattern). If belt tension is ballpark-accurate, maybe check whether the pulleys on the XY stepper motors are still tight on the motor shafts. The flat axle in combination with a slightly loose grub screw could - in theory - cause deterministic slipping / hysteresis that might look like in the picture.

Yes the belt tension has been checked and gantry aligned several times to both the tigher and looser ends of the belt specification.
The printer has also had the calibrations factory reset, so all self tests and calibrations have been completed again and passed.
And thank you for the suggestion, I will check that next. I have already checked both motor mounts and they are secure

I have checked both motor pulleys and they are also tight
