Flow, my printer is extruding too much?

    So I get better results if I lower flowrate to 95%, this is done on each print. How can I make it permanent?

    Save it in the profile of your slicer... The firmware has no option other than steps per mm for the filament feeding.
    You could possibly measure each filament with the calibration and calculate new steps per mm and then reduce that by 5%. Should have the same effect...

    Looks like it's still getting way to much filament:

    Stopped halfway trough

    EDIT:

    Stupid me, FR and Flow is not the same....

    Did you calibrate your steps per mm for your filament?

    It's a factory assembled Pro, but I might need to do it anyway it seems.

    You need to potentially do it for each spool, but at least each type of filament...

    Testing stuff here, and found my sweet spot for this filament to be 92% flow, but I've changed it back to 100% flow and instead decreased E-steps, from +310.0 to +280.0 without the big differences really.

    Still overflow of filament. Should I continue to lower e-steps further down until I see improvement?

    Tweak flow until you like the output. Fix in slicer or esteps or starting GCODE :)
