Here are other pics of that same issue

#

I tried lowering the acceleration from 500mm/s² to only 250 for things like outer wall and top/ bottom layer but it only made it worst it seems, the default max accel on my printer is 500 and im wondering if i can change it in firmware and if it would even improve mumy corners

I use pla+ from esun, the nozzle is at 200c, bed at 60, layer height at 0.2, infill speed is 70mm/s, outer wall speed is 35mm/s, inner wall speed is 45mm/s, top / bottom speed is 30mm/s, first layer speed is 20mm/s.
Acceleration is at 500mm/s² ans jerk at 8mm/s, retraction is 4mm.

lowering peint speed might help but im not printing that fast in the first place so im guessing there's an other issue, i also try tuning the linear advance on marlin to no avail, mauybe i did it wrong so im open to any suggestions.

check your seam its only on one corner right? try making the seam on one of the faces

the seam is in a corner but thats not whats causing the corners

pressure advance in klipper or linear advance in marlin can help with that also a quick Google and jerk settings may help if you can tune it on your current screen

late yacht pressure advance in klipper or linear advance in marlin can help with that also ...

i tried tuning linear advance but it didnt change a thing :/

#

i might try again because i changed a few things since when i tuned it but last time it didnt change anything lol

yeah just go for max or min values and see if it does affect it

#

i used their gcode egenrator and une the best number i got last time

#

but again i change the jerk and acces so results may be different

i tried again with thegcode generator and didnt get any improvements, what do you mean my max or min value ?

well thats a suggestion to actually try a bigger number or smaller number since changing it doesn't seem to affect the outcome, so we know that it is working to find tune it
