Little layer gaps randomly in prints on both my MK3S & MK3S+
Hi,
I have both a MK3S & MK3S+ along with a few Enders and for some reason both my MK3s give me these little layer gaps in my prints when printing them up vertically. I have used the Discord channel and made sure my Live Z was right so I don't think it's my Z and I can't seem to fix them where they can print a smooth vertical wall without the random little gaps. I've attached a few pictures of items.

Could those be where retractions are happening?

Possibly? Do you think I need to increase my retraction rate and test it or decrease it? Though looking at where they are don't most retractions happen no a layer change? those seem more randomly in the middle of the print

I've seen gaps like that if I had retraction too high or I forgot and had PETG retraction settings(3-4mm) in my PLA print profile. I don't think PLA needs near that much. when it happened to me I saw gaps in places just like that.

Thank you, I will test the retraction settings and see if that helps!

I'm printing something right now in PLA and I'm relying on the printer defaults:
Retraction Length: .8mm
Lift Z .4mm

Adjusting the retraction has helped a lot! Thank you.

in my limited experience, I've found that I've not needed to depart from the prusa defaults at all for PLA. PETG is a different story. Every vendor's filament is it's own beast. Which is why I'm using up most of my different vendors and standardizing one 2 to 3 and getting those dialed in. To compound things, each model can present it's own challenges...
When I get a new filament I usually print one of these: https://www.thingiverse.com/thing:923097
It helps me get my settings dialed in and it adds to my luck, which I don't think you can ever have enough of!

how are your settings now?
