This is not strictly about the BB, but with so many of us using S3D, I thought I'd see if anyone has any ideas. I've got a small test model I'm using to try to get to the overall best settings for printing with the 1.2mm volcano nozzle. One thing that is obvious in each print is that the top three layers have a different look to the rest. Seen inside S3D I can clearly see the different speed for the solid infill layers being indicated. I can't see why it's not obeying the same outline speed as other layers though. Any ideas?
