How I identified and resolved my direct drive extruder inconsistent flow and print surface artifact.
After release of this video I realized that many others have this issue. Thanks to people commenting here I was made aware of:
Prusa Issue 602 - [ Ссылка ]
Voron Issue 6 - [ Ссылка ]

In this video I walk through my journey to find the rootcause of this common issue with direct drive extruders:
00:00 Intro
01:30 Timing ruled out
02:04 Motion System ruled out (XYZ)
04:16 Bowden prints better!
05:11 Direct Drive extruder system breakdown
06:17 Troubleshooting methodology
07:11 First issue - Impact of hobb gear wobbling
12:33 Second Issue - Impact of filament diameter inconsistencies
14:39 Experimental gear from Bondtech
15:16 Third Issue - Plastic gear from BMG may also be in cause
16:55 Back to square one, issue is somewhere else
17:36 Fourth Issue - New theory about "Filament Walk"
19:35 Showing improvement from new Bondtech gear once Filament walk has been resolved
