Poor wall quality after overhang

Bambu Lab P1 Series Troubleshooting

I’ve started getting an issue where the part of the print AFTER an overhang will be blotchy or have large gaps in it and the rest of that side of the wall will have a bad finish. It’s not an issue with supports since its there whether the supports are there or not, rather I think it’s an issue with how overhang walls are printed slowly and then immediately after it tries to return to the normal wall print speed and that difference is both messing up the wall immediately after the overhang and also messing up the speed of that section of wall compared to the rest.

Are there any recommendations on how I should address this? Faster overhangs? Slower outer walls? Smoother acceleration? I’m on a 0.2 mm nozzle and generally using the .06 High Quality preset.

Sorry about that, here’s a picture. Also I was able to find that the issue resolves if I check “Don’t slow down for overhang” but I’m wondering if that’s the best solution or if anything can be done to fix the root issue.

I am having the same issue. Walls printed right after overhang walls have a bad quality, almost under extrusion kind problems. Did you find any other resolves than checking “don’t slow down for overhang”?

Nothing so far other than that setting.
