Me too, I have the same wave on X only.
I hope Bambu lab will have a solution.

Having still been unable to clear the artefacts I have decided and Bambu have agreed that the printer is going back for a refund. I will be keeping an eye on the situation and may return in the future. I wish Bambu Lab all the best with this printer and hope they get all their issues resolved quickly.

I wonder if installing smoother on the X and Y motors would help? https://www.amazon.com/gp/product/B071WG3SZQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I am also getting the same effect, especially on round objects. Almost like their might be a “ZigZig” X Y movement rather than a smooth X Y movement.
I have to replace my motherboard cooling fan, I may steal a couple smoothers from my Ender 5 and see if that helps.
I am also going to re-visit some of the Bambu Lab sample prints to see if it’s a slicer issue since theirs are pre configured and tuned.
Super noticeable on any “flat” surfaces. I’ve gone back to my Ender printers when I need buttery smooth prints. I hope BambuLabs fixes this sooner than later. I’ve put off ordering my second X1 Carbon and set my eyes on a Troodon v2.

Yep, when you’ll try I really want to know your result. It’s possible than Bambu works on this problem too. I hope…

Not sure it will help a lot but it maybe related to infill/wall overlap, as infill keep the sema direction and not rotate when turning the 3d model it still.make sens tha only X o Y is impacted : :Is that a problem ? micro-z-banding
Try -5% for overlap infill/wall (note the minus sign)
Try without or with tiny infill ratio
this really is annoying because most of the things I want to print have this effect also.
I did all the tensioning and else and dealing with support is a bit tiresome as they make you jump through the hoops.
Maybe we should post all the issues here and really get their attention, this is a big deal and one of the most frequent issues of this machine.
I think that if everybody does the test and report here, we can just simply redirect support here rather than having 40 people doing the same test with support.
We should all print the same model and report back with pictures. Thoughts?

It’s definitely a good idea to collaboratively test for issues. One has to take care not to overly criticize, but I see it the same as you that this issue might be important for some and ther should at least be a possibility to achieve a better result at a time when it is really needed. Maybe it contains a compromise, lower print speed for example, that would be fine with me.

I have two theories.
Poor K/PA values. The infill is over extruding at one end of travel where it touches the walls. This is causing a subtle ripple on the outer surface. Do you get poor seams on the same prints? does this disappear with gyroid infill.
Or
2x poor stepper drivers amplifying each others flaws when harmonizing in Core XY.

I’ve been having issues with this too. I swear it’s gotten more noticeable since the last firmware update. I thought vibration compensation was supposed to address this but it doesn’t like much better than my other core xy that has no compensation. Meanwhile I’ve added a sonic pad to my ender 3 s1 pro and have been getting really good results.

I am having the same issues on X axes efter updating the software. I hope Bambulab fixes this. The first half is printer at 50% speed. Filament Extrudr BioFusion quicksilver

I agree simple cylinder and a box.
I have not printed in PETG yet, only PLA and ABS and the results are the same.

Definitely agree on the doing a group test print.
Might also be worth saying what you have already tried doing in order reduce or remove the artefacts as well.
Come on guys let get the test prints done and results posted ASAP.

Seems to be the larger diameter shows it more. I had a test ring on my desk from a cup holder that shows it more.
I am adding a 90mm test to the Thingiverse link.
May also need to try one of the boxes rotated 45*. The artifacts are there, but faint.
I’d suggest changing it to vase mode to eliminate infill causing issues.
for the experiment sake and to remove any doubts to other parties seeing the results:
Please take a photo of the model while it is still attached to the plate, this way, the axis are self explanatory and will provide 100% proof of the defect orientation without further marking.
You can then identify them for your own sake once these are removed.

On round objects this could actually happen due to the way CAD software saves circles in stl, namely as n-gons, so a circle is approximated by a polygon with n sides, and n depends on your export settings.
Are you sure this is not what one is seeing on the photo of the round prints?

That would be symmetrical across both axes, correct?
I can’t tell orientation on the rings posted above.

That is a possibility. That question is beyond my skill set. My work is done on Fusion 360 freeware and exported as .3mf files. I don’t know how to smooth the circles out - if you know how to do that, post how or a link to teach me and others.
This I think where a box at a 45* on the X/Y axis my tell since the walls are straight…but again they are a bunch of triangles no matter what. The artifacts on my box prints are there, but very faint and I can not pick them up with the camera.
If you can make a 40-90mm ring, do a remix of mine and post it to try. We do need to see if it is a model issue or X1C firmware change.

The markings on my 40mm are at the bottom, and marked before I took them off the build plate. The large ring I don’t know what is X and Y, but it does not matter, it is there 360* around it. Before and after the seam which is vertical. That one is also 3mm thick with 3 count wall and 5% cubic infil.
If it’s there all around the ring, this could indicate in issue with the model.
Send me the stl you used and I’ll print it for comparison on my X1C.
