Multi layer rafts
Up till now I've only used a single layer raft where first layer detail was just too detailed (my theory being PETG will stick better to PETG than glass). I recently realised that Prusaslicer has the option to use multiple layer rafts, does anybody use this feature and if so why?
RE: Multi layer rafts
I have used it just to mess around. I have not found a benefit but would imagine it might make it easier to remove from the build plate.

Thanks. That was the only use I could find.
RE: Multi layer rafts
Hi:
I'm using Prusaslicer 2.2.0 linux64 and I can't see the difference on the plater when I try to print with our without rafts.
Shouldn't I see the raft layers after slicing? Or is it a "feature" that I just need to trust that the raft will come out.
After uploading to a 3rd party gcode viewer, I still don't see the layers so I am skeptical that this button is doing anything.
I would like to try rafts for a case where I am trying to print a part at an angle where support is needed in most locations under the model.

They should be visible in preview mode after slicing and definitely in a gcode viewer.

RE: Multi layer rafts
Maybe this is a nomenclature issue.
Attached is a picture from the plater where I requested 30 layers of raft, so I could see what Prusaslicer considered a raft structure.
What I see is actually just support material extended vertically by the number of layers requested. Even the first layer has spacing between filament lines.
I thought that a raft was a multilayer structure that was essentially filled 100% on the first layer, and then fairly dense on the second and third layers, such that the model and/or support could have very good adhesion to the build plate.
Cura was pretty good at this.
