First 0.05 mm print on my Prusa Mk3, no clue what's wrong, appears to be some underextrusion, it was sliced through Slic3r prusa edition using the default 0.05 profile with infill reduced to 20%, combining infill every 4 layers, and support material enabled with detect bridging perimeters enabled too.
printed with the silver PLA that came with the printer and the Prusa PLA profile
just did another print at 0.15 mm this time slicing through Prusacontrol with default settings and supports enabled and it turned out just fine.
also printed with the silver PLA that came with the printer and the Prusa PLA profile
just started another 0.05 mm version sliced through prusacontrol before i head off to bed, I guess won't learn, fingers crossed! will update tomorrow!
