    First prints, looking for feedback on what to look for in prints

    Just bought my first 3D printer, Ender 3. Using tinkercad and freecad, with cura for a slicer. Ender 3 is stock except for filament guides I printed and just added a octoprint. Have bootloader coming soon, so I can replace bios.

    Have printed a few calibration items and a few other items. Looking for feedback on what I need to be looking at on print and help identify adjustments needed. All prints have been recommended/default cura settings.

    XYZ 20mm Calibration Cube - https://www.thingiverse.com/thing:1278865
    Hatchbox Black PLA - 20% infill , Layer height .2, no other cura settings changed, tool at 200, bed at 60
    Looks pretty good to me, but I am not sure if I should expect more of if someone with more experience can point out issues with it

    Didn't get any major stringing but have a few bumps on one side. Hard to take pictures...

    Getting other colors of PLA today, may be able to see more details/issues with a color other than black...

    Hi. On the XYZ block looks like you have some z wobble going on and you can bump up the extrusion a wee bit.
    On the second one in your slicer turn on random seams and not aligned seams. The bumps could be from overheating and/or hatchbox filament. I buy their stuff and it is known for doing that.
