i think I'll mark with // all the lines to be easier. And I'll take a pic before modifications.
I have one more problem. During the print when I want to change the filament with change filament function my extruder does not retract the filament. It says directly ,,Insert filament and press button to continue" This only happend for unload lenght over 200mm. I have a bowden tube that has 600mm lenght so.....
Here's my code:
#if ENABLED(FILAMENT_CHANGE_FEATURE)
#define FILAMENT_CHANGE_X_POS 3 // X position of hotend
#define FILAMENT_CHANGE_Y_POS 3 // Y position of hotend
#define FILAMENT_CHANGE_Z_ADD 10 // Z addition of hotend (lift)
#define FILAMENT_CHANGE_XY_FEEDRATE 100 // X and Y axes feedrate in mm/s (also used for delta printers Z axis)
#define FILAMENT_CHANGE_Z_FEEDRATE 5 // Z axis feedrate in mm/s (not used for delta printers)
#define FILAMENT_CHANGE_RETRACT_LENGTH 2 // Initial retract in mm
// It is a short retract used immediately after print interrupt before move to filament exchange position
#define FILAMENT_CHANGE_RETRACT_FEEDRATE 60 // Initial retract feedrate in mm/s
#define FILAMENT_CHANGE_UNLOAD_LENGTH 300 // Unload filament length from hotend in mm
// Longer length for bowden printers to unload filament from whole bowden tube,
// shorter lenght for printers without bowden to unload filament from extruder only,
// 0 to disable unloading for manual unloading
#define FILAMENT_CHANGE_UNLOAD_FEEDRATE 100 // Unload filament feedrate in mm/s - filament unloading can be fast
#define FILAMENT_CHANGE_LOAD_LENGTH 300 // Load filament length over hotend in mm
// Longer length for bowden printers to fast load filament into whole bowden tube over the hotend,
// Short or zero length for printers without bowden where loading is not used
#define FILAMENT_CHANGE_LOAD_FEEDRATE 100 // Load filament feedrate in mm/s - filament loading into the bowden tube can be fast
#define FILAMENT_CHANGE_EXTRUDE_LENGTH 50 // Extrude filament length in mm after filament is load over the hotend,
// 0 to disable for manual extrusion
// Filament can be extruded repeatedly from the filament exchange menu to fill the hotend,
// or until outcoming filament color is not clear for filament color change
#define FILAMENT_CHANGE_EXTRUDE_FEEDRATE 3 // Extrude filament feedrate in mm/s - must be slower than load feedrate
#endif
As you can see now I have 300mm and it does not work. If I replace 300 with 200 everything is perfect. What could be the problem?
