H2D - Filament not being wiped during multi-color prints

Bambu Lab H2 Series
1

Hey all,

I’m having a strange new issue. When I creat muli-color prints, the left and right nozzles aren’t wiped completely during the process. This leads to an inch long filament sticking out and being drug around the print bed while the other head is printing. These accumulate and then stick the model or disrupt other functions.

I’m not certain if the answer is to change out the nozzle wiper mechanics or otherwise. It looks like the nozzles when they wipe are dragging the filament from the purge chute back to the bed, they just aren’t getting knocked off.

All filaments are dry, only using bambu PLA, etc.

Thoughts?

This is since last firmware update.

2000h of print with my h2d never had that issue and since last update Always have this 4-5cm of filament hanging .
Even when print is finished.

Hope next firmware or studio update will return to old purging. This is what also causes those hairs on prime tower lots of users report
