Cura 4.4 Support Oddity

[hartparr 0]

See attached part I'm trying to print. 

 

When building support, Cura is not doing it for the entire area that needs support no matter what settings I choose. It is leaving a gap and then just trying to bridge the gap with PLA.

 

Any ideas?

Huh. I see it too and it's happening on 4.3 as well. 

Thanks for attaching the model! I'll check with the team if this is a bug.

Sadly this is the stair-stepping again (somehow). I think we should look into rethinking that whole piece of code, given the amount of trouble it causes us and how hard it is to debug.

 

It does, most of the time, give a nice workaround though: Just put 'support stair step height' to 0.0 mm and the missing support will appear.

@hartparr - We have an internal ticket to fix this issue. Thank you for reporting it and providing the model where you see it happening! For Cura internal devs: CURA-6989

@rburema - Thank you for the work around. This worked for me. 

 

@territerriterri - Is 6989 a GitHub issue or do you track these elsewhere? 

 

For what its worth, I like the stairstep at .1mm. Having to go 0 to solve this issue does look like the support is going to hug right up against my part.

The CURA-6989 is an internal ticket for us in the Cura team in Ultimaker. We usually put it here so if a dev or QA engineer revisits this, they can refer it to an internal ticket. 😉 I'm glad @rburema's workaround worked for you. We are going to revisit the whole support generation feature, please bear with us! 🙂
