Slicing problem

[coolm8 0]

Hi,

It is the first time i wanted to slice a self made 3d model in Cura. It was an OBJ imported into Netfabb and then exported as STL. The object was modeled in Maya and is therefore hollow. Now the outer shell on one side does not get filled and leaves a hole in the object. See:

What do i need to to solve that?

Most likely you have intersecting faces somewhere, this usually causes these kinds of issues.

Hi Daid,

I have similar "blue-line" problem when sclicing.

This is the snap view of the g-code result: there are the "noise" blue-line movement evey 2or3 levels

and the "blue-line" will clearly affect the printed model:

I thought it's my model problem. But the Tornado from Ultimaker samples did the same:

I tried thin-wall quickmode or manually thin-wall with Joris on or off. The result was similar.

Do you know how I could avoid these "blue-line"?

Or if the blue-line couldn't be avoid, any tips to avoid the PLA going out when the blue-line movement? what about retraction more?

Thanks!

The images are not showing. But the blue lines are moves, not actual printed lines.

Hi Daid, Thanks for your reply!

Sorry about the missing photos.

I know that the Blue-lines should not be printed. But there are real lines affected by the the movement of "Blue-lines". Please see the model_print.jpg. You could see the extra noise PLA which is match with the "Blue-lines". When nozzle moves by blue-lines the PLA should stop but actually PLA still come out.

So I guess I need the right retraction parameter maybe. I use :

Retraction

Min travel: 5.0

Speed: 70

Distance: 4.5

Extra length on start: 0.0

Yes, known problem, not sure why it does that, but it does it. The same thing happens with the "vase with ear" from joris.
