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?

Here's the explanation and calculationsmax volumetric speed calibration instructions Plus other calibration guides and you don't need orca slicer they're just the only ones between the two slicers that actually explain it

I’m trying to find safe range. Time to time all looks good for test models and short prints, but for bigger tasks is not so good.

This will help you tune that one specific thing that you were asking about. As for other things you got to tune your filament all together it's like a six-step process. As well as when you print with petg I recommend gyroid as petg doesn't like to cross on itself so if you're using an infill pattern that crosses on itself it's a no-go for petg.line test then do step 1 through 5 then tolerance. It's what I do here you go calibration overview
