If you want a good raft you might have to use an older slicer. Cura was started well after the time when PLA was discovered and raft no longer needed (heated beds were well known but not that common yet). I believe the author at the time didn't really appreciate good raft design. Other slicers that had been around back before PLA (ABS only) and before heated beds (not many) understand raft better. Like Slic3r - I think slic3r was created back in the cold-bed-ABS days and raft was the only way back then.

Other slicers do support multi-layer brim. I'd really like to see this in Cura as well.
I primarily print with PETG which has a tendency to warp or pull off the bed. I am also using PEX as my build surface, which generally works well. However, if I just want to print-and-go without worry, the raft it is.
Thanks!

For me the raft means I would have to spend a long time cleaning the bottom.
I print petg with no raft and no brim. I use all the remaining tricks in my video above. I use PVA glue, rounded corners, squish, and heat. For PETG (printed 4 large petg parts yesterday) I used 82C on the bed. I put some filament on the bed at various temps and it got soft right at 82C so that was the temp I chose to avoid corners "warping" off the bed. Parts came out great. Bottom smooth.
