Try not to spread misinformation and just dont say anything you’re guessing without mentioning that you are just guessing
it did come to the slicer. it has nothing to do with firmware.
and i am currently using it on my A1.
I found that it helped to paint on the seam where I wanted it to be before applying scarf. Otherwise, even if using “aligned”, I found that part of a seam might appear in one place and another part somewhere else. i.e. they stopped being truly aligned together all in one place.
it does not appear randomly. on curved surfaces you will notice the location changes depending on the diameter of the curve and the scarf seam will also curve in a related matter.
if your seam is straight then i don’t know if scarf seam is even working.
Bambu studio doesn’t have that? What printer do you have? Mine is 0.20 mm Standard @BBL A1
A recent update changed the interface. It is now just a checkbox about scarf joints; I guess it isn’t experimental anymore.
it is under filament settings now as different filament react with different scarf settings.
