ok, for this realy special problem in the background (raft / none raft) it's perhaps not realy a bug, more of some kind of special problem.
I'm using this software for 4 weeks now and sure i don't get everything correctly.
But in the first way when i'm adding different process and tell him he should print it layer by layer and the result is something different,
for newbies it looks like a bug ^^
And on the other way, it could be done by the slicer. He could say, hey, this will not be printed layer by layer because raft is something different,
or he could calculate the layer by layer thing correctly, including the more than one first layer problem. I don't want to tell it would be simple,
but i'm no fan of "it's not possible" ;D
For your question "why you want use":
I'm getting very different models for printing and for saving time i want to fill my printing bed. But some parts does have enough ground that
they don't need to be rafted and ... when directly printed on bed, the baselayer quality is finest you can get.
The other parts are often realy made delicate, sometimes my wallthickness is just 0,5mm. The x400CE is doing'em fine, but they need a raft
otherwise this parts are getting off from the bed and destroying everything.
Thats why i thought it would be nice to use Raft/non-raft at once.
But thanks for your idea with the skirt / brim idea. It looks more like the cura antiwarping layer and could be in the moment the best
answer for my problem.
Just a shorty ... S3D offers options for raft ... so i could use just 1 raft layer. So the raft is
Thanks for answering you all, keep on printing
