I am new to this forum, so sorry for any mistakes.
I have an issue with my homebuilt hypercube by Tech2C. Im using a MKS GEN L board with TMC 2208 driver. The last bit of every path gets not extrudet. I tried everythig. Belts are tight, rods ar straight, tried different filaments every jerk and acceleration setting in Cura.Coasting ist turned off. At first i thought it is an mechanical issue. But the Infill showed the same symptom aswell.
There are some more pictures at imgur.

Please help!
Tanks for your support.
Have you done an E-steps calibration for the extruder?
For a new build that’s a good first step calibration.
Hey there, thank you for your quick response. When you mean Stepps per mm with E-Steps. Of course I did. Top and Bottom of prints look perfect. I am in 3D Printing for quite a while. But now with my first printer i built myselfe I came across this issue.
Just checking 
so is this only an issue on the infill? If so maybe its a speed issue; the extruder can’t keep up perhaps?
I tried a lot of speeds, accelerations and jerk settings. The test you see on the pictures are printed with 45mm/s and 1000mm/ss jerk is around 8-10. No slipping or grinding at the bowden extruder.
