I have a related question:
Suppose in my Ender3 I set M221 S85 in the cura machine code, to set the flow rate to 85%, then use the hand wheel on the printer to select "Tune" and then "Flow" and reset it from 85% to, say, 95%, then what flow rate do I wind up with, 95%, or .85 x .95 = .8075 ~ 81%?
Note: And, does it matter if I print via USB or if I use an SD chip to carry the cura-generated code to the printer port?
I have been ass-uming that I would get 95%, an increase of flow rate (which is reflected in the printer setting in the tune/flow menu), but now I wonder if it would actually decrease due to the potential multiplication of the two numbers.
I guess this is more an Ender3 question than Cura, but I think it is relevant to the original question starting this thread.
What say you?
