My BIQU H2 direct drive extruder was plagued with the clicking gears that several complain about, although I didn't have any print quality issues so I left it alone except for slowing down my printer to minimize the sound. Well today while cleaning out some filament debris I found what I believe is the problem. Basically the holes that hold the bearings are a tiny bit too large so they are able to wobble in place. This video will show you how to fix that with a virtually free solution using Kapton tape.

Hopefully this fix works for you. let me know in the comments how it went.I enjoy reading the feedback.

thanks for watching
