Hi everyone, I’m extremely new to 3d printing, and have taken over a printer from a friend who doesn’t use his. I’m trying to get those smooth prints I see people having, and I understand I need to get a smaller layer height to achieve the details. However my stuff keeps coming out looking like the pictures below.

Any idea what’s going on and how I can start fixing it?

I’m printing PLA filament.

  • Nozzle temp: 215
  • bed temp:70
  • nozzle size: 0.3mm
  • Layer height: 0.1mm

Thank you!

    To add to this, I would highly recommend not worrying about using a .10mm layer height until you have reliable prints at .20mm height.

    Trying to get finer detail is just compounding issues onto a print that looks to have quite a few things wrong.

    I agree with you on underextruding. Easiest way to test would be for OP to measure 150mm of filament from the entrance of the extruder and mark it. Set nozzle temp to 215 or so, and manually extrude 100mm. Then re-measure to your mark and see how far off you are. If it’s way off OP needs to calibrate his extruder motor steps.

    Also as other people have said, might be worth trying a different filament, especially if that filament is really old.
