show them this forum post, and point out the bed wobbling in the video.
Going to keep updating thread incase anyone else has this issue in the future:
Heard back from Snapmaker team for the wobbling bed video they suggested to fix it like this: What should I do when the slider of the Linear Module comes loose? ā Snapmaker
I responded about voiding the warranty and it hasnāt been a year of owning so waiting to hear back about that.
For the smooth vertical bumps they are tweaking a gcode I sent them but havenāt recieved one back to try yet.
Overall customer service is a slow and lengthy process. One response in the middle of the nightā¦If anyone else has suggestions let me know

I suspect this is the whole answer to the problem. The seams are consistent with the X or Y axis directional changes. Rotating the print orientation will prove this out.
This is basically the same guide I referred to, but in this case from the official support website. As they are asking you to do this, this should not void your warranty. I think the guide on the form actually is more detailed and easier to follow than the one on the support site.
@jgb Yeah the lines donāt appear to move regardless of the seam moving. i have been print just tubes now for faster printing and checking.
@brvdboss Right, I was afraid it might come to that.
I will wait to hear back from Snapmaker and hopeful they can send me new linear modules for the bed but doubt it since I couldnāt even get replacement magnets for my Enclosure doors as they are too weak to even keep the door shut. I use gaffers tape now for that haha. Also rather not have to play around with internal mechanics as I have no faith in myselfā¦Re: bed frame upside down. SMH
UPDATE: As predicted I was not successful with the fixing of the linear modules.
Snapmaker sent me 2 linear module replacements. It appears now that after two test prints the vertical Lines are gone.

Thanks for the update!
This means that you were able to fix the play in the linear module but the result was still the same, or that you basically broke the linear modules and needed new ones 
?
but it were the modules. Which ones did you replace, the y-rails?
Yeah so basically it only affected curved lines or at least thatās when i started picking up on the vertical lines. My modules i took apart as instructed by snapmaker but 1 out of the 4 bearings would not adjust to spec. I then tried to put them back together and thatās when things went wrong for me. They sent me a new set for the Y and replaced them and now everything seems to be printing good. no vertical lines. I have printed 1 tube like i have to test and 2 of my ghosts and they have printed now with no issues. This leads me to believe that MooseJuice was correct on the bed rocking and was the culprit.

@designsbywilliam yeahā¦ unfortunately @MooseJuice has far more experience with weird issues than a lot of us on here, much to his chagrin. I remember when it pretty much took the entire forum to help him solve one of the weirdest issues ever seen. Heās like an MLB pitcher, print results are the ball and the machine is the batter, machine will just slam that ball right at his head full speed.
Updateā¦So printed another shark which i use gray filament for and i actually notice one vertical line still, its much better now like not as noticeable as before but i guess this issue is still a mystery.
Wanted to let everyone know incase of someone else with similar issue in the future.
@designsbywilliam could you post a picture of the latest result?
@designsbywilliam is it possible to share the stl so I can inspect the model itself?
I can send later but at the moment it happens to anything that is circular in shape. Still happens to the ghost and the tube i just didnāt realize it because printed on white so hard to see it. When I changed filament and printed another couple shark heads I realized it was still there its just more faint and less noticeable. But if I print something square-ish I donāt get it at all.
@designsbywilliam you said anything circularā¦ that sounds like linear advance calibration is needed. Itās gotten better from what you stated, but not resolved, so I donāt think itās a hardware issue.
I did linear advance but after replacing my linear modules was having gaps in layers. I did a extruder calibration and linear advance again. Maybe the new linear advance was the reason it does look better? Iāll try it again and see if I get a different result.
