As I understand, the larger the curvature on an object, the thinner the selected layer height gets with adaptive layer height.

Then I would expect the green part at the side openings of the 3DBenchy in the following picture to go up a bit further, no? Or is that some bridging feature?

The same effect can be seen in the OP picture. Would be nice to learn a bit more how the algorithm works.

Does not help much, since there is no explanation there

Explanation and implementation can be difficult. See this thread to see if it helps. The last messages are about playing with the numbers. Sometimes, ya just gotta fiddle around a bit.

The term "curvature" is not well-defined, so that is not the case. A large curvature could be a large radius. What you want is to have thinner layers when you have a surface with is very close to but not horizontal. That is it has a small angle (compared to horizontal). To get that defined you need thinner layers. You can see you get blue areas (thin layers) when you have features with near-horizontal angles. On the lower part of the benchy it is the top surface of the hull that induce thin layers then at the upper part of the door it is green because we only have the "vertical" part of the house there and then it becomes blue again when we approach the near horizontal part of the door opening and so on.

Got it. Just got an idea for the (far?) future. The uppermost part of the hull induces small layers on the cabin as well of course. The same effect might occur if you have multiple objects on your build plate. So the idea is that one could e.g. print "more vertical" parts at a multiple layer height compared to "more horizontal" parts. But that requires an algorithm which can separate an object into connected and not connected parts.

edit: btw. I was confused as I somehow expected the better layer quality to be on the right of the scale (no specific reason for that). But as the scale is about the absolute layer height, confusion has gone.

You are looking for an explanation. I just pointed to an example of how tweaking a simple number can change its affect. If a visual example is not helpful to you at all, then my apologies.

If we are to report problems here, then I have a new one. There is nothing in the monitoring tab after I start a print. Using the app I can see the video feed so the printer API is working.

No need for apologies, thanks for trying to help. I was looking for an accurate definition of what the number is, not so much what tweaking it does. Thanks.

Could you include a screenshot where we can actually see what is going on? The text onscreen could have some hints to what is happening. Also logs... (but you knew that)

Edit: wait, is it the forum that scales the images down?

I find the newly setup selection of everything clicked when you first click on an input field annoying.

(...)

But, the new way is counter to every other program I can think of and requires a lot of retraining just for one function in just one program

It was requested by someone, so I implemented it, and then the pull request was tested and accepted. It was especially meant to select text when tabbing through fields, I guess it is somewhat disruptive to you because it also selects all text when you click in a control. I must say that even the address- and search-bar in the browser I use to type this answer behave the same way as the fields in the sidebar now behaves. But the change is easy to revert if more people feel strongly about it.

Yeah, I get that. But when you are just trying to select one numeral, say, to change 0.24 to 0.54 is a pain. Like I said, old man, new tricks, retraining.......uggghhhhhh...LOL

Edit: Oh, it should at least be consistent across all fields. Currently it is not. The input fields for translate and scale do not behave the same way. And, it would be nice to be able to input direct rotational values as well in either local x, y, z or world x, y, z. Preferably both.

I have made a suggested change to the behavior here:

With that change the text only gets selected when tabbing through fields, but not when clicking in a field. I don't know if it will be reviewed and merged in time for the final release of 3.2

That is actually behaviour I am used to. Pretty standard as far as I am aware.

Noticed the same thing, it also only effects the dark theme

Okay wondered that, having the same issue

Did anyone already try the new 'multiple buildplate' feature? You can enable/disable it in the 'preferences', love to hear some feedback!

I like the concept of it even for the UM2 been able to see a list of files you have on the build plate is very handy.

Here is some feedback

1. When you add a second stl to the build plate and right click new built plate, and they have sliced the first build plate says 0 hours 0 minutes for print time.
2. Arrange to all build plates could be worded better as from what I can tell it just merges all the plates to one.
3. Save the build plates with a Cura project if I make a set of build plates for a bunch of batch jobs but want to edit a setting or two every once and awhile would be nice to just open a cura project that brings me back to where I left off.
4. Would be nice if the build plate menu remembered if it was expanded to see the files really annoying having to click that every time I open Cura.

Yes, I tried with a current project, all the parts dont fit on one buildplate, so I got to try adding buildplates and this was pretty neat

But I wish when saving the project, it maintains the buildplates as they are set up, when I save a project with 3 buildplates, and quit Cura, when I open the project again, only 1 buildplate is

loaded, the other models and the other buildplates holding them are gone.

The layer view has definitely slowed down a bit.Still leaks memory too.......

Interesting. It should be faster, because backface culling was enabled (less work for the GPU)

The slow rendering is not a GPU problem. In all other programs the same or more advanced graphics can be rendered without any slow downs. Actually, there should be no work for the CPU as soon as the model has been loaded by the GPU after which all affine transformations and drawing is done by that. Are you processing the data in Python for every frame - then it’s not so strange it is super slow.

No idea, I dragged the screenshot of the entire Cura window in the reply field. I will reproduce the problem and attach the Cura log here.

@hoegge and @kmanstudios, what GPU do you have? We got some similar reports on github this weekend, and I noticed that both of those reported an AMD GPU. There could be a specific issue between how Cura does things and AMD drivers. I'm just trying to get to the root of the issue.

Nice rig  but why win8.1 ??? why?? worst windows in history!

Because it is still supported and I am not keen on Microsquash taking over my updates and such. I do not like the idea of rebooting in the middle of a 30 hour animation render and having it fubar my files doing so. It actually runs just fine. 8.0 sucked, but have no issues with 8.1. My other desktop has the same configuration but it is Win 10.
