Cura Starts layer in Mid air

[mrtinfy 2]

 

Hey All, I've come across this issue where cura tries to start the walls mid air when it could easily start from where there is already material (yellow circle) as you can see in the picture i enable bridging but that doesn't keep it from starting mid air, I can't use support as I'm printing with PETG. Is there any existing settings I could try to make it start from one of the fins of the impeller? (yellow circle) if not this would be an awesome feature for the next update 🙂

If you could post the Cura project (.3mf, in Cura get it read to slice then go to File > Save Project) that might help.

But if you have support turned off, Cura will just slice things that will never print successfully and not give a stuff:

In your case it's not bridging because your walls are round and bridges can only be straight. Looking at the size of the model, it could probably never do bridges that long anyway, especially with PETG (it's too stringy and is just going to stick to the nozzle if there's nothing else for it to attach to, like existing model). You can submit a feature request if you'd like though (make sure to include a copy of your model).

 

Why do you say you can't use support with PETG though? I find it comes off with only a teeny bit more hassle than PLA, and then there's just some strings to get rid of. You want support that's hard to get rid of, try printing TPU at an angle.
