Ringing\Ghosting on printed parts

Dew_Controller_Box_v2a_0.2mm_PLA.gcode.zip.txt Knowledgeable Ones,
I'm sure someone here can point me in the right direction, but I have an issue with my CoreXY printer, adding lateral 'ghost images' of any hole in the sides of printed parts i.e.
I'm using PrusaSlicer 2.2.0 to generate the gcode, and using the same slicer, but sending the 'same' gcode to my Prusa MK2s machine, allowing for differences in gcode flavour etc, I do not have this problem.

I don't think its anything with the machine configuration, as all appears to be ok, apart from a hardware tweak I need to make to the bed to level it off, so is it due to PrusaSlicer adding artefacts, or is it the Duet board interpreting\caching things ??
Hopefully I've given all the info you require, including the gcode file (zipped & renamed to a txt file)
All hints gratefully received.

Reduce your jerk values
M566 X2400 Y2400
Try 600

Thank you, thank you, thank you,
Those settings came from the configurator, as I've never changed them, but at least I now know where to look, I'll also have a look through Prusa's code to see what they have set as the default..
FYI, I've tried 600, but there are still artefacts, so I'm printing multiple parts to find the optimum settings....

https://duet3d.dozuki.com/Wiki/Gcode#Section_M593_Configure_Dynamic_Acceleration_Adjustment@Veti I also suffering from ringing on Z axis and would like to try DAA. AFAIK jerk settings should be increased when using M593?! Currently I have 600. Is there any recommended jerk value to start with?
Thanks, Martin

i have not heard of ringing on the z axis before.
as describes in the documentation only acceleration has an effect on daa.
-
@Veti Ehhh...sorry....Y axis
Current accel is 2000. Can I keep that or should I increase it? -
keep in, measure the the distance of the peaks and calculate the frequency based on the speed printed.
then print the same object and judge if it improved the result.
if you change to many variables at once, you dont know which effect each had. -

Now to the last issue: my Z axes problem. Just ordered metal mounts for my three SFU1204.
