Flow Confusion
I'm trying TPE filament for the first time. From what I have read, flow should be set to about 115%. I'm using the "FLEX' filament setting as my starting point.
In PrusaSlicer 2.7.0, I see:
Filament Settings > Filament -> Extrusion Multiplier = 1.15
This seems to match up with what I expected.
However, when printing, I looked at the i3 MK3 display window which is showing:
Tune -> Flow -> 95
Shouldn't this be showing 115? Or am I misreading something?

On the prusa profiles is a part of a printer start gcode block. Printer Settings>Custom Gcode>Start Gcode. You have to be in expert mode to see that section.
You will see a line something like M221 S{if layer_height<0.075}100{else}95{endif}
RE: Flow Confusion
Those are different things, they both affect the amount of filament but are applied at different points. So extrusion multiplier is then multiplied by the flow.
so EM =1 as flow 95 then its 95%
EM =120 x flow of 95 is 114%

So where is the "Flow" specified?
