adaptive layers treshold

Recommended Posts

Posted · 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.

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 :
