Errant threads from hops messing up otherwise beautiful print

[TracyE 0]

I am printing some end caps for a device. they look gorgeous printed at high resolution but one little thing is messing up a 9-hour print. The print head travels across the perfect face of the raft and leaves a thread or two that mess up the top. I have included some pics below of the raft, the final print, and the layers shown in Cura where this problem happens.

Is there any way to tell Cura not to do this? If the print head would travel outside the raft rather than across it at these few times the problem would be solved. Is there perhaps a setting to make that happen?

Many thanks to anyone who looks at this.

I personally almost always use Rafts: They stick better to the build plate while also being easier to remove. They keep narrow parts from curling up and small contact points from coming off. But Rafts always mess up the surface quality.

That said: Since you are printing essentially a large circle (no narrow or small contact points), have you tried it without a raft?

It will probably be harder to get off the print bed, but your quality might improve and hopefully you won't get those nasty threads.

P.S. I've not found a way to stop those threads in Cura 15 or 2.
