You sir should be awarded an gold medal and an high five, i feel so stupid! Ofc i need to define more movement if i klipper should do the movement instead of the slicers “assumptions”…
I went with
max_extrude_only_velocity: 60
max_extrude_only_accel: 1500
and now it works flawlessly, had even to turn down ret-speed to 40 whilst printing to not slip grip on filament!
Is there any deeper math or study to find best accel speed?
Cant thank you enough i was so sure it was some slicer setting so this would taken ages!
Just look at the progress, now i was able to print my bracket no problems at all at speeds i didnt think was possible with bowden with this quality
