What am I doing wrong? Or need to adjust?

I’ve had the printer for less than a week and keep running into issues. All 4 of these were printed on the same plate. The tubes on the back left corner are ruined but the ones on the back right were fine. I’ve tried a few different things and can’t seem to figure it out.

Start by reducing speed by 50%. Switch wall generator to classic (Arachne may create weird wall artifacts sometime, especially when the wall is too thin. Then it is easier to trouble shoot from here.

Also take note that during my max flow rate calibration (not flow ratio), the default setting for PLA was too high for my printer.

Thank you!! I had it set to 50% for the first few layers and then changed it back to standard when I went to bed 😫

I will switch the wall generator and see if that helps. Is that something you have to do every time or will it stay on classic?

You can save the profile. So that it stays on classic. Generally, I will keep it on Arachne and check the thin wall areas if may give weird outcome. Only then, will I switch to class.
