Top of print (weird)

[ubi90 0]

Hi Guys,

I got a problem on the tops of my prints... some holes and bad "finish".

I tried to print same models files on others printers (other brand) and no problem.

Any ideas ?

Please see pic attached.

This is called "pillowing" and is caused primarily by a lack of cooling. Get the fans going top speed to help with this issue. Increasing layer height may help as well, as will increasing the thickness of the solid top fill.

Fan speed already at 100 /// cant do more

for layer height... i like it at 100um

increasing the thickness of the solid top fill => how do you this ? this might be the only solution :(

thx for help

Increase the top/bottom thickness setting. Make it a larger multiple of your layer height - you might need 10 layers or more.

Thx, where about in Cura do you change this ? cant see thos options even in expert settings (maybe they are called differenty)

On the left side on the "Basic" settings tab under "Fill" you have a setting called "Bottom/Top thickness".

So, if you want 10 layers on the top surface, and you are using 0.1mm layers, set the "Bottom/Top Thickness" to 10 x 0.1 = 1mm.

I can't see your drop box photo. Did you delete it already? Could you upload it and edit your post? To put a picture on ultimaker forum (so that it is still visible years later) click "gallery" link in top left of this web page, then click blue "upload" button. After uploading edit your old post and click "my media" next to the smile, then "gallery images".

Did you verify that your side fan/fans were spinning? Sometimes the wire is loose. Here is more about pillowing including a sample picture and solutions (post #10):

By the way .1mm is fine. We just thought maybe you were at .02mm or something where pillowing gets worse.
