Real previews with different settings Cura 2.5

[paul9 20]

Hello everybody!

With CURA 2.5 (beta) I'm simulating printing using a nozzle of 0.6 and one 1mm, when I preview in layers with the same settings, but only changing the nozzle and entering what I get from 1mm problems similar to under-extrusions in parts printing more important.

Some of you can help me solve?

If the nozzle is thicker, it might be that it needs to extrude less in the second pass. The layer view, even though it looks realistic, is not a realistic representation of what it will do when printed.

I know its asking a lot, but that does kinda negate the purpose of 'layer view': to spot issues in your print before it prints. How do you know know which issues are real and which aren't?

In fact I made this print using Cura 2.4 where, however, do not have this print preview, and the result was just like you see in the preview offered by Cura 2.5, that's why I wrote realistic.

You don't. This is why i was not so sure we should have this feature. But all the other slicers had it and at some point we also had to participate. Because if we don't, people keep using the lack of a "realistic" rendering as an argument why Cura is falling behind.

If you want a perfectly right layerview, it's going to take a loong time to build. You would need to take a whole lot of physics, material flow, deformation, etc into account.

Could it be related to the model thickness?

I found that layer view is quite representative of how it actually prints, of course not 100% the same but it can help detect some issues

Exactly

I have made a first printing using Cura 2.4 not having the preview as of version 2.5 I have not seen the result, but if I had installed and tested with version 2.5 maybe now my press would be much better.
