Help: Interior Stringing on Random Layers of Tube - solved

[twinword 0]

 

Hi folks,

We just got our UM2 last week and spent the weekend running a bunch of tests of various parts and troubleshooting. So far most of the issues that have come up have been solvable using the forum/Google and we're generally getting good results. But we're stumped by this one.

When testing the Julia Vase #4 from Thingiverse we're getting an occasional layer that has wall-to-wall stringing happening for the entire layer. Then it goes back to normal for another 2-3 cm, then another layer with strings. The entire model ended up having 4-5 layers like this and it was really tough to clean up.

I tried running it again just now with fast travel speed (200) and retraction settings dialed in, no solution. When I reviewed the sections in Cura, there are several that show light hatching across the interior void (which shouldn't be happening).

Images included (if I did it right), hope someone has a solution. We're using the latest builds of Cura and native UM2 firmware (not Marlin).

Holler back

Try going into the expert settings: Expert -> Open Expert Settings On the bottom right of the pop-up there's a group of settings called "Fix horrible", the first box is ticked, right? Try unticking it and have a look at the layer view again.

This isn't stringing - the pattern is regular. This is a purposeful support layer. *and* it's visible in Cura. In cura you can slide the layer slider on the right side down until you can find the problem layer. DO NOT print anything until inspecting the layers first.

Robert's suggestion, although it may sound bizarre, is very very likely the fix for your problem.

Thanks guys, that was it. Weird that it was checked by default...
