H2D High Flow Nozzle shows no change? (Solved-ish)

Bambu Lab H2D

Hi All, I’ve never used a high flow nozzle and I managed to get two from todays stock.

I’m not noticing any change in time at all when changing the slicer from the stock .4 nozzle with the High-Flow .4mm nozzle. I understand we can change the flow rate and speed manually, but I’m wondering if there is a spec sheet with the slicer changes that would help increase the speed. Thanks.

EDIT: I actually haven’t solved the issue, but Bambu does NOT update the flow values at all when switchingh to High Flow

HF max flow rates are set identical to standard flow rates for most filaments except PLA Basic and Matte. My guess is bambu will update these values eventually but until they do there will be little speed advantage seen with most filaments on standard profiles. “Generic PLA” and “Generic PLA High Speed” have the same max flow rate on standard and HF, you need to bump them yourself to see a speed increase.

You’ll also need to adjust the filament settings to High Flow, which will increase the maximum volumetric speed from 24 to 32 like (Sample PETG HF)

That is what I was talking about.
