Print not clean from inside

[shaihem 0]

Hi!

This is my first participation in this wonderful community.

I printed a vase but within the print there are lines all over.

While it should be empty from inside.

Retraction is enabled.

PLA and ABS not working.

Slow speed wouldnt make a difference.

What do you think?

Hi @Shaihem,

welcome to the community and our forums!

Could you tell us what 3D printer you are using?

Do you have some screenshots of your settings?

You say retraction is enabled, but based on the output my first thought would be that it isn't.

Can you verify that while printing, the feeder is actually retracting the filament? (so there is a quick back and forth motion?)

Any print that I print and is hollow from inside, the printer acts as if the retraction is off although it is enabled.
