Gaps between layers?

[User_7465]

hi guys, can anybody tell me why these gaps occur between the layers?
the filament is fresh out the box,
happens with other filaments too
motor driver is high ventilated
nozzle is not clogged.

any thoughts?

Most likely you are underextruding e.g. not enough material is being fed into the nozzle. Have you tried increasing the flow of material.

What printer are you printing on and what are your printing settings?

actually everything is fine when there is not so much retraction or not small perimeters.
retraction seems fine though
