What could cause the strange part on the right? The whole surface should be the same, it’s a 90° wall, so nothing that should look like this. Can’t see anything strange in OrcaSlicer. BambuLab A1 Mini with Creality PLA+

    Spontaneous ideas for troubleshooting:

    • Disable the stepper motors, slide the head to the position it would be in when printing this section, and check for any irregularities in the rail or belt.
    • Clean the hotend.
    • Try to print the part again, see if there is damage at the same section.

      Started the print again because i need this part multiple times anyway. It starts to “fail” at the same corner again.

      Edit: Not exactly the same damage, but at the same height. Looking at the last print, it’s not just that corner, it’s all around at the same height.

        If it’s a band one thing you can check is if the build plate is sufficiently torqued down. I spent ages chasing down a weird z issue, to the point where I converted my ender 3 z axis to being belt driven, and would still get really weird bands at certain heights. Turns out the bed was ever so slightly loose and at certain z heights would go into a tiny resonance frequency causing bands in the z axis. I’m not too familiar with the a1, but it’s a possibility that no matter what I researched I never saw mentioned

            Let me know if that helps! I hope so since it was a pain for me that nobody suggested. I got frustrated with that one enough that I got a p1s but still decided to tear down the entire enter and put it together to see if it fixed the issue (it did) so I could give it to my buddy

          Just a band. But not all the was around. It is at overhangs and a little bit after them. But not before overhangs.

            If it’s only overhangs then you may want to look at increasing the time between layers or increasing the part fan speed on overhangs.

            This way there’s time for the layer before to solidify enough before adding more heat and melted plastic above it.

            May not be it but it does have a kind of “overheated” look to it.

        Same height? Check if the vertical axis has a bump/rough spot right there. I’ve found that single vertical point issues tend to mean I need to lubricate the rod again.

        If prints are failing at a certain height, you might have a z axis issue. You can try cleaning, lubricating, and calibrating the z.
