Is your printer enclosed? Do you have a print cooling fan turned on?

I use very faint fan with the small tipped duct blowing to the print (ABS). Someone now says that not to use fan with ABS, but I haven't got problems with small parts. Small blow "freezes" the plastic and stops the curling. Not 100%, but it helps. Example: [youtu.be]
Now I have extended the tip with aluminum foil tape.

There is something like:

We don't use any cooling fans on ABS as they always have caused us warps!

Have you tried printing with a Brim (as opposed to your raft you mention)

And what temperature is your bed at?
