Help with possible retraction issues

[Yagabaga 0]

Hi all,

 

 New here, so I hope this is an appropriate place to post. Having trouble getting test prints to have good results, possibly retraction? I've ran test prints (auto towers) and thought I'd be getting close. But I still seem to be missing something. New to FDM printing, so any help is greatly appreciated. Please let me know if there is more information I can provide to help diagnose where I need to make adjustments.

 

I'm also inclined to think some of the "zits" are due to my filament age, and not being dry? (Gave up months ago and has been sitting). Have new filament on the way since I'm on the last roll.

 

Thanks in advance for any help that can be provided.

A lot of them look like they correspond with the Z seam (here's a close up of where the Z seams are on the... rear end):

You don't have Retract at Layer Change turned on and some of those seams don't require travels so they're definitely not retraction problems, which probably means overextrusion (more filament in a spot than there should be). Try lowering Walls > Outer Wall Wipe Distance to 0mm. If that leaves small bits that are underextruded (there's a tiny gap) try moving the wipe distance up to 0.1mm. If it's still overextruded, leave the wipe distance at 0mm and turn on Experimental > Enable Coasting (you might need to play around with the with the Coasting Volume to find the ideal amount).

Don't forget Slashee's Silver Rule™: Small scale testing is your friend.

 

The zits on the helmet's visor are a little more confounding: they're definitely not retraction related because there are no retractions up that high:

(Retracted travels are light blue). If that looks like a crapton of travels, that's just because that view is all travels. There's not too many on any given layer:

 

But there also aren't any Z seams in the centre the visor:

However I notice you have Infill > Infill Before Walls turned on. This can make the infill push the walls out a bit, and some of them look like they might correspond with the ends of infill lines. Try turning that off. Especially when using Gyroid infill, you're losing the main benefit of printing infill first (which is that the walls can grab on to the infill when they get printed, but that's not really needed with PLA anyway) because there's so few points of contact with the walls.
