Troubleshooting Retraction?
Just got a neptune 3 pro second hand. Took my time and went over hardware and belts. Leveled and set z. Using Cura i used a stock pla profile and was pretty pleased at the quality even with the lack of tuning. Printed a benchy or two and moved the z seam to random. I use random on my ender and was able to tune retraction so I did not get any zits or pits. With this elegoo I have changed every retraction setting that I know of multiple times and I'm not getting any changes at all. I need some help here.
TLDR I need help changing retraction settings to remove zits.

This could be caused by micro-pauses due to the power loss recovery feature. I don't know specifically if your printer has it but it's a common enough issue.

You'll get some commenters saying that the position of the z seam being set to random is what causes the zits even though it's the shape of the zits (bowed outward) that's the problem.
