Every time I print something I get these random bands on my prints that look like layers that are just too thick. I’ve tightened my X-axis belt to the best of my ability, and my Y-axis belt is tightened as well. Though I don’t think it’s that because it goes around the whole print.

I’m using Cura, .28 mm layer height, 20 % infill, all on my Ender 3 in PLA at 200 °C nozzle temp and 50-60 °C bed temp. I’ve attached some pictures of a calibration cube I printed, it is squished a bit because my Z-axis wasn’t calibrated properly, but I’ve since fixed that and the problem still occurs.

    $\begingroup$ @kosteklvp Supposed to be 20mm, ended up 17.3 mm. I printed another after calibration and it ended up with the same dimensions and layers, so now I’m thinking I have a whole other problem on my plate (haha) $\endgroup$

    $\begingroup$ Yes, check and tighten everything around Z-axis. Check also, if your Z-axis isn't missing steps. $\endgroup$

1 Answer 1


Problem solved everyone!! Turns out I was actually having two issues caused by the same thing. My inaccuracy in the z axis and those weird lines were both being caused by either my z axis stepped not receiving enough current or that the collar around the z axis lead screw wasn’t tight enough. I tried both of these solutions at the same time so I don’t know which it was.

Link to a post with the same issue, with possibly the same solution. Thank you @0scar for showing me this!
