Hi guy
I have some question.

  1. For 1st photo. Support around base sometimes look like this. How to solve this?
  2. For another photos How to solve this ? I have two assumtions about it.
    I notice that the problem spots are where the hot end stop to change moving direction (cw to ccw or ccw to cw) My first assumtion is that spot is too hot because hot end stop at that point and I print it with out print fan. Other assumtion is extruder motor run too fast. I print it with PLA and I print 2 vases and there are spots on same positions for both vases.

ps. Sorry for my english skill.

What printer and material? And are the edges supposed to be sharped or fillited?

@Orion_Stargazer welcome to the group. You have valid questions, but as noted above a few pieces of information will be needed.
It can be derived you are on a prusa i3 variant. Also noted, you have a large brim setting and you are attempting a spiral vase.
Which slicer and what is intentional in your print?

About spot! Even big spots is gone, small spots still remain! So use knife!

Sorry for little information. @Griffin_Paquette @Brandon_Satterfield
I print it with Prusa i3 rework 1.75 mm PLA 0.4mm nozzle generate Gcode by Cura
layer hight 0.2
Shell thickness 0.8

Bottom/Top thickness 0.6
Fill Density 20

print speed 70
print temp 210
Bed temp 75

Support type Touching buildplate
Platform adhesion type Brim

@Orion_Stargazer truly most settings there are pretty acceptable.
I might slow speed to 55mm/s, layer thickness .32, width .5, temp back to 200.

You can see these are all minor changes. I think what is happening is the speed and layer height are causing the plastic to push to one side when turning.

Again, these are just opinions.
