First of all, please apologize because I am sure this topic has already been treated.
I am trying to improve overhangs on K8400 and tried this solution:

In order to compare before and after, I printed 2 double sized Marvins

The one on the left is without the duct and the one on the right is with the duct. This photo is not that good… it seems that left one has been “burnt” which is a flash artefact.

The second print is better but is far to be perfect. I could give some more photos if needed.
I print with colorFabb PLA/PHA at 195°C and 4200mm/min.
I also use a Replicator 2 which has this duct which is a great solution for this printer.

I would really appreciate if somebody could help me with this issue.
Thanks a lot and have a great … print!
