@jay_s_uk thanks a lot!
only 60mm/s? First time I tried with 0.6 nozzle, layer height 0.36 and base cura speed 140mm/s.
Do you have some recommendation? change only nozzle or whole hotend? if hotend what you recommended? dragon HF or rapido or volcano or something different?

@jay_s_uk I have this https://trianglelab.net/products/dde-direct-drive-extruder?VariantsId=10109 V6 hotend
So I am on limit of hotend? And if I want print with higher speed I need new high flow hotend?

Hi,
I have ender 3 v2, duet 2 board, direct drive extruder.
I calibrated extruder for feedrate 6mm/s (G1 E100 F60) calculate e step value and printer works fine.

I tried print some model on higher speed with 0.6 nozzle and printed model looks underextruded. So I tried measure 100mm and extrude on higher speed 60mm/s (G1 E100 F600) and missing 37mm! I tried it more time and result was always same, missing 37mm filament to extrude.
Material was PLA, temperature 220. I tried 30mm/s feedrate (G1 E100 F300) and missing 7-8mm filament to extrude 100mm.

My question is, how setup extruder to working on slow and also high speed? where could be problem? Thanks for any help\

My config.g driver setup:
