[Help] Prints look pitted or bubbly
I've had my MK3 for about 2-3 weeks now and the first few prints were great. I didn't really see issues with any of the prints.
I've been printing a jet engine from thingiverse and the first dozen prints were fine and didn't see issues. Then all of a sudden my prints are turning out bad. I've been using the same settings and nothing has changed.
I did run a calibration check again to make sure but still am seeing issues.
Here are two prints. The grey is Prusa PLA and the white is Milca PLA. The surfaces should be smooth like the first few layers on the grey print. But then it just turns out pitted or bubbly (blobs).
When not using my PLA I it store back in its original bag with the desiccant packet. It's not in direct sunlight, but it is just sitting there.
Prusa support gave me a link to troubleshoot a clogged nozzle that I will try later.
Thank you in advance for any advice.

try Tom's reviews on Filament types... he gives some good advice on properties and what to look for... my first guess is your a bit to hot.
Re: [Help] Prints look pitted or bubbly
Thanks, I'll try that as well.
Like I said, the settings have mostly been default and the first 2 weeks of printing were fine: 210 / 55 or 215/60 are my usual settings.

Firmware 3.1.2 RC1 adresses issues like that with small layer heights, might be worth a try.

[update]
So I watched it print and found that it was leaving globs of PLA when it lifted or started a new layer.
Instead of using PrusaControl I used slic3r so I could tweak some things. I increased the retraction from .8 to 1.5 and also decreased the flow rate from 95 to 90.
So far it seems to have helped with my issues. Still tweaking it and might bring down the temperature too from 210/215 down to 205 or 200. Melca PLA says to have it between 180-220
