Surface Artifacts
Getting this weird issue lately. It was fine before, but now I have to drop my speed slider to 30% to get rid of it. This is a 100% infill print.

And yes, the nozzle was way too close to the bed on the first layer. The one time I don't babysit it at the start
I'm thinking it could be filament temp and cooling related. What type of filament is this?
Overture PLA+, that would have been at 200*.
Unfortunately it's not that, the PACF was doing the same thing
Are you printing fast enough? The artifact looks like from motor resonance. Try VFA test in Orcaslicer to see if it disappear at specific speed
I hadn't thought about that test. That was using the default slicer settings in orca, just in case my profile fucked it. I'll try that
Well it's not that...
Speed range, 100-300
Do you have good cooling? it seems like the faster you print the worst it gets
It's a 4028 set to max out at 70%
So yes
And I know it's working because I can hear it across my house
Actually... Turning the fan off cleaned up all those artifacts. I still have the resonant xy banding, but it's smooth otherwise. Running the test again with the fan capped at 40 now
Interesting .. i know that sometimes turning the fan of completely helps with filaments like ASA or Nylon but not PLA.
Yeah, it's just the first time I've seen surface artifacts from too much fan, versus not enough.
I don't have similar issue on my prints .. I'm also running 4028 and the higher i run it the better results i get but it gets too loud so i cap it at 70%. Could it be a faulty 4028 that resonates ? but even so it should not be transferred to the print as above
200 is also really low for those speeds. might want to try and bump the temps up

That first pic looks verrrrry familiar. 😜
