adaptive layers treshold

He,

into this beautiful slicer, there is a parameter "adaptive layers treshold" with a default value set at 200.0 .

At which angle corresponds this value ? 

is it tan(angle) =  0.2 which means an angle of +- 11.5°  ?  Just to clarify,  in such a case,  a switch angle of 45° should be set at 1000.0   because  tan(45°) = 1.0. Correct ?

many tks.

Phil

Tests with different values for the  adaptive layers threshold parameter.

We print our locomotive with 0.081 layers. it's good, although some too small details are not printed optimally. With layers of 0.05, the details are improved, but the overall quality seems less good. The use of adaptive layers is therefore an excellent solution. Congratulations to ctbeke.

I found   this post  and  this other post

Well, I did not found a mathematically understandable answer to my above question, but I understood how to set up this superb function.

In my case :

Layer height : 0.081

initial layer height : 0.16

Adaptative layer maximum variation : 0.03 which allow layers from 0.051 till  0.111

Adaptative layers variation step size : 0.012   ( = 0.051, 0.063, 0.075, 0.087, ………..     0.087 , 0.099 , 0.111)

I then performed tests with different values of the "adaptive layers threshold" to compare the results with a print made either only with 0.081 layers (20H46) or with 0.05 (33H03).

The result shows a variation of the layers height (and therefore the duration) not constant. I have summarized it in the table below.

After a visual study, we decided to use for this model a value of 500, which generate this slicing :

I don't see adaptive layer threshold setting anymore?  Is it hiding?

It has since been renamed to "topography size". More details are available in this commit: https://github.com/Ultimaker/CuraEngine/commit/76e9e27b300eee37e6bf0f41af96450c6eed4779.

More details? Not really, unless you're a Mathematician or programmer!! This was hardly documented until this post (Thanks @OUPS65 !!! 🙂  )

 

Now you've CHANGED it and the popup AND the Settings Guide are both typical "clear as mud" descriptions. I worked for a top 10 Computer company back in the day and they had a policy of "NEVER let the engineers write the manual".

This setting and the newest change are a perfect example.

 

GREAT piece of tech, GREAT paying attention to the clients' needs and filling them, LOUSY documentation.

Don't shoot the messenger...

 

Anyways, there's a reason it is still in the experimental category. For one thing that usually means it's not clear how to use the settings.

Hmmm. Yeah, not really yelling at YOU, but just venting. A program as sophisticated as this needs documentation that's clear. "It's experimental" is an pretty lame excuse, actually an experimental item should have MORE documentation, not LESS, eh?

 

How are people supposed to use something that you want feedback on if there's no proper instructions and there's been a major change to it's use?? Are we supposed to just print endless failures until we find something that works? For that one model?!!??

 

Seriously, this is a candidate for a "This is Broken" post on Reddit, LOL.

 

Regards to YOU @ctbeke and thanks for all the hard work you put into this forum, believe me I get it!! Stay healthy!!
