"overextrusion" on edges

[Schoepsi 1]

Hey guys,

I´m currently working my way through Cura using an UM3 Ext (coming from S3D) and got a problem with getting sharp corners. My corners look something like this (a little bit exagerated):

So, I guess the error is caused because of not changing printspeed and/or flow when doing edges, but how can I change that?

I know that this is probably a very common error, but I really didn´t know how I should call that thing...so I didn´t find anything with the search function

Thx

This effect happens when printing at low jerk low acceleration

You can read more info on https://printedsolid.com/blogs/news/a-solid-foundation-for-high-quality-corners

Basically with current marlin and extrusion control to avoid that on corners the only solution is to change your accel/yerk control in cura (hidden options). Doing this will speed up the print speed but will make the print look with lots of ringing effect because the printhead of um3 is heavy and... well more stuff.
