Hey CA, have you ever heard of linear advance or played with its settings? From what I read it has to do with the pressure in the nozzle and when it is set correctly you should be able to reduce your retraction to 0 or near 0. This is what I found and have been reading about it: https://mattshub.com/2017/10/02/linear-advance/ I am going to start playing with this tonight I think.
