Support missing at the bottom due to stair stepping #6379

Closed abrooks-Accutime closed 4 years ago

abrooks-Accutime commented 5 years ago

Cura does not add support where it needs support. This problem was also found in Cura 4.2.0 and Cura 4.2.1 No Support No Support 2

Could you also share the model and the settings that you used to get this?

abrooks-Accutime commented 5 years ago

Is there an email I can send this to since I don't want this model in the public?

nallath commented 5 years ago

Sure, you can send it to j.vankessel@ultimaker.com

nallath commented 5 years ago

I don't know what the problem is, but I've tried to slice it with 4.2 and 4.3 (although I am running it from source) with the profile that you provided. In both cases I got correct support:

4.2: Cura42Support

4.3 SupportCura43

I'm guessing you must have other changes than the ones you sent me. Could you share a project file of the setup where the issue occurs?

abrooks-Accutime commented 5 years ago

Let me know if you can see the problem know. I don’t understand what going on here and how you can see the normal support.

We were able to reproduce this issue last Friday. It turns out to be a bug related to stair stepping. We'll raise this and see if a fix can be made, but it won't make it for 4.3.

As a workaround, you can set the Support Stair Step Height setting to 0.

Sorry anybody can help to explain if change “Support Stair Step Height‘’ to ‘0’, What will be impact? Can I rest assured change it?

Sorry, as I know there is an official released 4.5 version, I had install and tried but no solve this issue. Why your 4.5 beta fixed it...

Internal discussion on this here: CURA-6989

abrooks-Accutime commented 4 years ago

cnfengjie,

I think I'm getting you confused to what my issue was at hand here. I had an issue where there will be no support from the build plate to the 90 degree overhang. All I know is if I have any issues with the new software, I would just go back to Cura version 4.1

Ghostkeeper commented 4 years ago

I don't think this is fixed in Cura 4.5 yet. Our ticket on this is still open at least.

nallath commented 4 years ago

Our internal ticket for this has finally been resolved. This should be fixed for 4.7
