[Stringing in middle of part]

Hi all

I'm using Cura 4:11.0 and I need to stop the nozzle from moving in the middle of this part as I'm getting stringing.

Material is TPU so very stingy.

I have tried a small test piece, see attached.

How do I stop the nozzle from travelling in the middle of this part. It's a long tube that fits over something so any stringing inside will be impossible to remove.

As you can see it has 4 slots that seem to be causing the problem, I don't mind stringing in the slots.

Can anybody point me in the right direction as I have tried all sorts of settings but can't seem to get the right one.

Thanks in advance.

Sorry I think I just saved it as .3mf file.

Thanks for showing me the layer thickness, I didn't know it was there, yellow is 0.35mm, no wonder it didn't print very well.

Here is the correct file.

Hi

I have attached the .3mf file.

This was done in Cura 3.2.1, I don't use 3.3.1 as there is a problem with it. I found the print times were longer in this version. I believe the bug has been fixed.

Print time for this is shown as 6:11, without adaptive layers turned on, 7:22.

If you need anything else just let me know.

Hi Brulti

I used adaptive layers as at times it cut the print time by quite a bit, on one part it went from 16 1/2 hours to 14 hrs 11mins.

I did a small test piece which was the centre section of this part about 2 inches high.

I used exactly the same settings as before only I turned off adaptive layers and it was perfect.

I am just saying that if you have a tall part and you use the default setting you could get a bad print like this.

I think Cura is a great software and use it all the time for printing, and I understand that parts of it are experimental.

I am trying to be helpful.

I have used adaptive layers to reduce print times and improve quality.

My latest print was a high part, 180mm in PETG, 0.25mm steps.

As you can see the side walls are pretty crappy until it reaches the angled face.

I used the default settings for adaptive layers.

Just a warning if you have tall parts.
