Linear advance, what to look for
-
It sounds like you are having the same issue I was having. I have a fairly long bowden tube and couldn't see any change in my pressure advance settings. It turned out the problem was I wasn't going far enough into the pressure advance values. I wound up needing to go up to 1.485 to get the improvement I was looking for.
To save time, I used a script-driven pressure advance object like this one:
https://www.thingiverse.com/thing:3442071It uses post processing to increase the pressure advance for every Z layer so you can test a large range of values in just one print - whichever layer looks best you just measure height with a caliper to figure out the pressure advance value you need.

Thats a pretty awesome one
i will definately bookmark that!Though i actually just printed my most neatly looking piece of a boat last night..
It seems that it was all due to a failing extruder
so messed up i didnt see this earlier.. i feel so dumb...
But thats jusy how it is.. cant change what has happend
But i will play around with pa when i get it stable for more than this one filament
And thank you for your help everyone
seems that a little bit of info from all of you made it all work!Im currently running 8mm @ 40mm/s and its perfect.. when i cant feel retract points when i run my finger over them, i will say its approved
