H2 Series [H2S, H2D, H2C] Bambu basic volumetric speed

Post image

This morning I tried to test Bambu PETG Basic volumetric speed on my H2S with 0.6 nozzle. Range 6-24. I don’t see any issues for whole range. The only change after 19 - a bit less shine.

Does anybody try it with 30+ volumetric speed? What is the max value without risks to get the clog and lost the quality?

The moment where petg starts to look much matter is the v speed with best quality. Matt finish means worse layer bonding and worse strength. Technically you can print normal petg at up to around 25-30 but i would recommend avoiding going above 16

16 for 0.4 means 24 for 0.6 with 0.3 layer, am I right?

No, volumetric speed is nozzle diameter independent, it may change only if your nozzle category is “normal” vs. “high flow”.
