Bambu Printer Seam Tuning

I am seeing an obvious seam line on my PETG prints and would like step-by-step guidance on which settings in Bambu Studio and on the X1C itself will eliminate or disguise it. I haven’t pinned down whether it is technically a vertical, horizontal, or random seam, so I’m open to trying the different coasting, wipe, or random-start options you recommend. I can share photos, a copy of the current project file, and the exact machine firmware if that helps you reproduce the issue. What I need back from you is: • A concise list of slicer values to change (layer start point, seam hiding, flow, pressure advance, etc.) with the reasoning behind each tweak • A short set of validation prints or G-code snippets I can run to confirm the improvement • Any Bambu Studio profiles you create, exported so I can import them directly If we get smooth walls with no visible seam, the job is done. Happy to hop on a quick screen-share or provide log files as needed.
