Update on my conversion to Klipper.
At first the corners didn't look any better than with RRF until I came across a post today that refers to extruder smooth time.
The standard is with Klipper 0.04, which I also use.
Switched to 0.01 and the corners look awesome.
In the article it was said that some extruders can not cope with the smooth time and then you have to get smaller. see my pictures.

@jay_s_uk many thanks. It work and install is done
@Phaedrux I have write T0 at custom settings are not defined and save the config.g.
I am so happy.
Found the bug. It was due to the contact resistance at the on-board connection. I thank you for the help and patience
@fcwilt i mean the config post from phaedrux

Rapido Hotend
Hextrudort Extruder ( ~ 20mm tube from extruder to hotend )
Test with extruder on toolboard and on the MB direkt but the corners issuse ob both connection.
Test with IS on and off at both connection.
My PA bevor the issuse was 0.035.
When I turned up the PA to 0.04, the wall on the corners open it.
Need you more Info?

I print a simple Cube with 40x40x2mm
I found the mistake. It was the slicer. I accidentally swapped relative and absolute extrusion. As a result, the skirt was still printed and nothing came out of the nozzle during the actual printing

@Argo ok. Nice test from him. I find for my Hevort 0.02 smooth time and 0.044 PA. Worked nice. I hope my Info can help Duet.
@Argo said in Issues with pressure advance since RRF 3.4:
So altering the smooth time value did improve your corners and PA alone did not?
PA alone didn't make the whole corner look nice. See the picture with the corner sticking out in the direction of travel. Only with the change of smooth time and renewed PA, which was then higher, did the corners become so clean.
I couldn't find any differences between 3.3 and 3.4.x, but I still have a picture of a test where the corners became nice with PA. As now with klipper. The Artikel from sebkritel is that who I read.
@R4ffers oh yes.
@dc42 is there also something like pressure advance smooth time under RRF? A few clippers have the problem with the high smooth time, but those who have problems are mostly DirectDrive extruder users. Maybe that's an approach you can follow.

@dc42 Many Thanks. Unfortunately, I'm not an electrician and can't read anything out of the schematic. If it were a blueprint of machines I could do that 
Hi
Which Sens resistor value is set in the RepRap firmware for the TMC5160?
I will only use it as an emergency backup. Sure if RRF fits again I'll switch back, I think. I'm already a fan of Duet.
But to test whether my hardware fits, I'll try Klippers. The last parts will arrive in the days for the test with me.
Yes, definitely.
If I increase or decrease the extruder pressure, I can influence whether there is more or less overshoot. But I can't get rid of it completely.
@gloomyandy no, on Duet 3 6hc.
I think that not only z but all axles brake harder. But I'll record it and open another topic and ask if Duet wanted it that way.
