Hi

I bought a "cheap" (well for someone) 3D printer for prototypes and iam trying to figure out the settings. The documentaton for the printer is really poorly made, the user manual is a joke, so iam seeking help on the internets.

My printer makes the surfaces really rough and bumpy, with ocasional small hole like this: [spoiler][/spoiler] If anyone would have an idea what causes this, it would be apreciated.

Material: ABS
Ex.Temp.: 230°
Surf.Temp.: 70°
Nozzle: 0,5
Layer:0.25 (awailable: 0.08, 0.125 or 0.25)
Fillament 90%honeycomb (or whatever it is called in english)
