One month ago, I didn't really know what 3D printing was. Yesterday, I designed in FreeCAD my first model and printed it. What an amazing experience. (lemmy.world)

I still have no idea what I'm doing really. Just too determined to give up I guess, and it's been such fun. Anyway I made a guitar pedal light switch cover. Still a lot of work to do, and every time I look at FreeCAD the wrong way, the model breaks, but it's been a fun experience nonetheless.

On a side note, anybody have any idea why the face of the model is rough textured, while the foot switch on the lower half is flawless?

Seems to be underextruded a bit.

Probably something to do with temperature or your nozzle being slightly clogged.

See if you have the setting for "ironing" turned on in your slicer.

    Thanks, everyone seems to agree on the under extrusion bit, so that definitely seems like what it is. I'm pulling my hair out trying to figure out exactly what. I may look at the e steps next. Ironing is not turned on, and I just cleaned the nozzle.

    Before you go through a bunch of calibration, I'd see if it happens with a different filament. Those black particles there are likely something with a higher melting point than the surrounding PLA, otherwise they'd "smear" during printing. I'm betting you're hitting some intermittent clogs. See if the problem happens with a single color filament.

    Thanks, I hadn't considered what made the marble in this marble white. I noticed this with my previous filament as well. This was a dual color PLA with under extrusion issues. I still use the original plastic extruder, and I bought it second hand, so no idea how much wear is on that arm but it's been in use for several years at least. I ordered an aluminum upgraded one and a filament dryer, and they should be here tomorrow. I'll upgrade the extruder, dry the filament, and check esteps afterwards to see if that was my part of the under extrusion.

    I don’t have a prusa, but can you calibrate E steps on that printer? That can definitely result in a nice looking first layer and following less-filled layers if it’s off.
