I am using a plugin called EEPROM editor to attempt changing them to those values back to those found in 2.0.9.1., however, unfortunately, it is not allowing me to do so, as these numbers would be above the current maximum. I was just hoping to see if there was a gcode that I may use to change this? Or is this set in the firmware necessitating that I download and edit your provided configuration.h file to do so? I very much appreciate your willingness overall to continuously upload the firmware that you compile time and time again, so I just want to share my appreciation over this as well. Thank you for the help.https://git.pickysysadmin.ca/FiZi/cr-10-v3-marlin-config/-/issues/11Look at filament unload rate2022-06-04T23:01:42ZEric ScheweLook at filament unload rateFrom the blog

Hey eric thanks for the work you have done on this firmware couple of things i have noticed
really the only main one anyhow is the stock filament load and unload is set at like 400+ mm at about 40mm/s (cant recall actual values) but ungodly high you may what to update that in your config
found this to be more suiting and not filament chewy
#define FILAMENT_CHANGE_UNLOAD_FEEDRATE 10 // (mm/s) Unload filament feedrate. This can be pretty fast.
#define FILAMENT_CHANGE_UNLOAD_ACCEL 20 // (mm/s^2) Lower acceleration may allow a faster feedrate.
#define FILAMENT_CHANGE_UNLOAD_LENGTH 10 // (mm) The length of filament for a complete unload.
// For Bowden, the full length of the tube and nozzle.
// For direct drive, the full length of the nozzle.
// Set to 0 for manual unloading.
#define FILAMENT_CHANGE_SLOW_LOAD_FEEDRATE 6 // (mm/s) Slow move when starting load.
#define FILAMENT_CHANGE_SLOW_LOAD_LENGTH 0 // (mm) Slow length, to allow time to insert material.
// 0 to disable start loading and skip to fast load only
#define FILAMENT_CHANGE_FAST_LOAD_FEEDRATE 10 // (mm/s) Load filament feedrate. This can be pretty fast.
#define FILAMENT_CHANGE_FAST_LOAD_ACCEL 15 // (mm/s^2) Lower acceleration may allow a faster feedrate.
#define FILAMENT_CHANGE_FAST_LOAD_LENGTH 20 // (mm) Load length of filament, from extruder gear to nozzle.
