Is it possible to Set up speed in % and flow in % by Slicer

I can't find anywhere how to set up print values programatically which I can change directly in the printer by turning the knoob: print speed % and flow %. Does anybody know how to do that?

'Flow' affects the extrusion values created in slicer.   within slicer 'Diameter' and 'extrusion multiplier'  affect the calculated extrusion value.    there is no direct one for one control...   
there is a command in some profiles, which conditionally sets the flow value as the file is created   

M221 S{if layer_height<0.075}100{else}95{endif}

 

this sets the flow value to 95% for all layer heights above 0.07mm layer height

Speeds are set in slicer  on a per item basis

I expect you could add a custom gcode to modify the speeds  similar to the lcd display setting but this is a clumsy option

@joantabb thank you for the valuable response 🙂 That's exactly what I was looking for ! 🙂 Would you mind if I ask another question: Where I can find the name of current firmware of Prusa printers? Is there any wiki page for that or it is somewhere obfuscated in the code in the official github repository? Am I right the current name is Marlin?

It is always wise to get more than one opinion... as for trusting Prusa? No way man....

the generic firmware type is Merlin, but the actual firmware is modified by prusa to "prusa-firmware"

that is correct, Prusa Firmware is a Branch off Marlin, that will probably never return, as there are so many differences now!
