Good day all

I struggled with blobs on my print surface and did not matter what I tried, I could not get a smooth zitless surface.
Negative extra restart distance / Coast at end / Wipe Nozzle / Temperature / Force retraction between layers etc.- all with different mm testing. I could minimize it on some prints and sometimes had under extrusion problems on other prints due to a negative extra restart distance or one of the other settings. I was fighting blobs all the time.
This is on a direct drive extruder pumping 1.75mm filament into a original E3D V6.

With S3D V3 I checked the new retraction during wipe movements function, reset my extra restart distance to 0, Wipe distance = 5mm and suddenly all the cursing/swearing and struggling for months, came to an end.

I printed 11 different objects at about 35 hours and there are not even one blob or zit present on any of them.

I never really had issues with my direct drive printers, but this new feature has been a huge help for my bowden machines!

I find that print speed also affects zits and blobs on the exterior... lower outline underspeed helped my prints greatly.

Ditto, it looks like there has been an improvement to the slicing engine.
