blurps or zits or bumps showing on exterior
I'm getting tiny bumps showing up sporadically on this side of print. What is this caused by and how to fix?
Material is PLA+, 220°C, 18mm3/s, 0.6 nozzle with 0.3 layer height

Could that be where your layers are starting? 220c seems really hot for PLA... Also seeing some artifacts that look either like belts too tight or input shaping disabled?
I lowered the temperature to 205°C and ran input shaper calibration. Looks much better! Thank you!
It's really incredible seeing input shaper work first hand!
@gywilo a good trick is to align your seams or place them on corners.
if you're using PrusaSlicer, i often tend to rotate parts 45 degrees, set infill direction to 0 degrees and then align seams to "rear". That places the seams at the far end of the part in a straight line and since it's rotated 45 degrees that's usually a corner.
@miklschmidt this is a good trick, will start using, thanks!
I aligned, this print like you say; actually still getting some bumps
That thing has no corners, nowhere to hide! But yeah those can be optimized, try "retract on layer change"
there's actually no Z/layer change in this area, layer change happens on opposite side of part
