Bumps on one side of the slope?
Hi there,
I just printed a pedastal for something. The pedalstal's got two slopes. One looks fine to me, the other got small nudges all over the place.
Has anybody seen something like that before and could give me a hint on what I've done wrong?
Printed it with PLA, 0.15 speed nozzle setting on the 0.4 standard prusa nozzle.

Most likely from uneven cooling. More air gets blown from one direction than the other and the part geometry shields one side from getting as much airflow.
Easy to check, if you rotate the part 180 degrees and print does the uneven side stay in the same position.

Thanks. That might be an idea. I checked with the print-file. The lower (and bumpy) side was pointing to the front. I'd expect this being exposed to the airflow more than the backside (airflow coming here from the right in the picture).
Just out of curiosity I'll give it a try with the rotation to 180dg. If this stays the same I assume a rotation of 90dg should give me even results on both sides (not saying it will be fine, just equal result).

I would also try the Structural setting (I hardly ever use Speed, not worth the drop in quality for me), and raise the infill to 20%.
