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!

    I bet your temp is way too high and causing the stringing. 8.5mm retraction seems pretty excessive as well so try reducing your temp and retraction settings. I personally print PLA at 195 and I believe Bowden extruders should be around 4-6mm retraction (don’t quote me on this. I have a direct drive extruder). You can print out a temperature tower that’ll increase the temps every few layers so that you can see which one gives the best results. After this you can do a stringing test print to see if there’s an improvement.
