speed FILAMENTCHANGE

SONIC300077

how to change the speed in FILAMENT CHANGE mode.

I need to slow down, change FILAMENT, where do I find this parameter?

The speeds defined also for G10/G11 are used here. So enable that feature and edit the config values.

I proexperimented with G10 g11. not exactly what you need!

is there a line in the code that is responsible for the rate of change of filament

In extruder.cpp

void Extruder::retractDistance(float dist, bool extraLength) {

    float oldFeedrate = Printer::feedrate;

    int32_t distance = static_cast<int32_t>(dist * stepsPerMM / Printer::extrusionFactor);

    int32_t oldEPos = Printer::currentPositionSteps[E_AXIS];

    float speed = distance > 0 ? EEPROM_FLOAT(RETRACTION_SPEED) : EEPROM_FLOAT(RETRACTION_UNDO_SPEED);

#if MIXING_EXTRUDER

    if(!extraLength)

        Printer::setAllEMotors(true);

#endif

    PrintLine::moveRelativeDistanceInSteps(0, 0, 0, -distance, RMath::max(speed, 1.f), false, false);

#if MIXING_EXTRUDER

    if(!extraLength)

        Printer::setAllEMotors(false);

#endif

    Printer::currentPositionSteps[E_AXIS] = oldEPos; // restore previous extruder position

    Printer::feedrate = oldFeedrate;

}

especially

    float speed = distance > 0 ? EEPROM_FLOAT(RETRACTION_SPEED) : EEPROM_FLOAT(RETRACTION_UNDO_SPEED);

where you see the 2 values from G10/G11 config. But also see that they are stored to eeprom so you need to change them there.
