Edit 23/03/26 : I can name the issue now: Z Banding issue - however all solutions available I've seen is not applicable on the K1SE model as the drive motor and other attachements are not located in same place or parts are not the same as the solutions I will link (incase some else find them beneficial). Great Vid on Z banding (various machines) https://www.youtube.com/watch?v=omKbSE_DWkY Article Creality https://www.crealitycloud.com/post-detail/6225cf9dfc277e6f868d50ba -------------------------- Hey everyone, looking for some advice 🙏 I’m struggling with these wavy layer lines and can’t quite pin down the cause. Adhesion is good, machine is stable, and it happens across multiple filaments (all dried). No drafts, new nozzle, machine cleaned, belts checked and seem fine. I’ve scoured Reddit, Google, and YouTube but haven’t found a clear answer yet. I’m printing on a K1 SE, so I’m starting to wonder — is this a machine-specific issue or something I’m doing wrong? At this point I’m not sure what else to troubleshoot next. I’d really like to dial this in and get cleaner, smoother layers. Has anyone experienced something similar or have ideas on what I should check next?
