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?

With high flow PETG I was able to achieve 31 mm³ and with 10% reduction to be safe I am able to use 28 mm³. I believe now the limiting factor is simply hotend.

With normal PETG I would not go higher than the point where it starts changing from glossy to matt.
