First finished print - Some issues. Any specific advices?

K8200 3D Printer K8200 - Issues while printing
1

Hi guys,

I tried to print this ( thingiverse.com/thing:732516 ) with the following settings:

  • 3 mm PLA filament
  • 0.3 mm extruder
  • 190° hotend temp
  • 50° mirror bed temp
  • 0.2 mm layers

and I obtained the following:

Generally I’m not completely disappointed, but there are many things that I’d like to solve, in particular:

Uneven layers in the z direction (the surface is “rugged”):

Burnt filament, together with general messy finishing

And last but not least, look at the bottom: it seems that when filling layers, sometimes the extruding material “bursts” and leave a stripe of excessive, melted plastic.

Any advices would be greatly appreciated!

Thanks in advance.

Hi

It looks like your extruder is a little hotter then 190C
You should check your thermistor for correct positioning.
That might clear up some of the problems.
