Add extruder load/unload in LCD Menu Prepare

[garaguido]

Is this possible to ad and updated the program lines ( original from Glenn West for RC1) in ultralcd.cpp for loading and unloading filament to bowden extruder ?

1. Menu Prepare - Preheat ABS (Or PLA)
2. Menu Prepare - Unload Filament
3. Menu Prepare - Load Filament
4. Menu Prepare - Feed Filament

With1 meter bowden tube, adjust your code for your bowden size.

Change this in ultralcd.cpp

static void lcd_prepare_menu()
{
    START_MENU();
    MENU_ITEM(back, MSG_MAIN, lcd_main_menu);
#ifdef SDSUPPORT
    //MENU_ITEM(function, MSG_AUTOSTART, lcd_autostart_sd);
#endif
    MENU_ITEM(gcode, MSG_DISABLE_STEPPERS, PSTR("M84"));
    MENU_ITEM(gcode, MSG_AUTO_HOME, PSTR("G28"));
    MENU_ITEM(gcode, MSG_LOAD_FILAMENT, PSTR("G21 G F200 E10"));
    MENU_ITEM(gcode, MSG_FEED_FILAMENT, PSTR("G F1000 E1000"));
    MENU_ITEM(gcode, MSG_UNLOAD_FILAMENT, PSTR("G F1000 E-1000"));
    //MENU_ITEM(gcode, MSG_SET_ORIGIN, PSTR("G92 X0 Y0 Z0"));
    MENU_ITEM(function, MSG_PREHEAT_PLA, lcd_preheat_pla);
    MENU_ITEM(function, MSG_PREHEAT_ABS, lcd_preheat_abs);
    MENU_ITEM(function, MSG_COOLDOWN, lcd_cooldown);
#if PS_ON_PIN > -1
    if (powersupply)
    {
        MENU_ITEM(gcode, MSG_SWITCH_PS_OFF, PSTR("M81"));
    }else{
        MENU_ITEM(gcode, MSG_SWITCH_PS_ON, PSTR("M80"));
    }
#endif
    MENU_ITEM(submenu, MSG_MOVE_AXIS, lcd_move_menu);
    END_MENU();
}

Yes.. it is possible... But the M600 Filament Change command is available from the LCD Panel. And the user does get full control over those types of things. Can you give it a try and see if it handles what you need?

/**
 * Filament Change
 * Experimental filament change support.
 * Adds the GCode M600 for initiating filament change.
 *
 * Requires an LCD display.
 * This feature is required for the default FILAMENT_RUNOUT_SCRIPT.

From which Marlin version is this aplyed RC8 , and enable it in configuration.h ?

[Jinxycob]

you found it yet?. have a look in the Configuration_adv.h folder

[garaguido]

I found it , but is it only for the ULTIPANEL ?
I use the RepRapDiscount FULL GRAPHIC Smart Controller.

[Jinxycob]

still works I use it all the time cracking feature just do it! :P
only becomes visible under TUNE setting once you start printing
though its still not altogether what you wanted as a preloader

[garaguido]

Nop dos not working by me, even by start printing .
What MarlinRC are you using ?

[garaguido]

It is working now thanks fore your help , but that is not my idee of using it
It was verry simpler to integrate this in de LCD menu , my use of it is for loading / unloading the filament in the PTE tube at PREPARE , before printing , not for changing a other filament color .
The code I get (see higher up) dos not working , iI get errors in Arduino IDE

[Jinxycob]

its a funny one a loader feature seen it on a couple of printers out there have it,but I think the wise folks behind marlin considered it waste of time. i think!! I dont speak for them. because manually its just quicker to do it by hand before printing starts and right after the warm up.

@garaguido
If you're going to post code in messages, please format it correctly. I have fixed it above.

a loader feature

Pre-loading filament has been implemented as part of the M600 feature. The only requirement is that you heat the nozzle above minimum extrusion temperature. Then the option becomes available in the LCD menu. This is only the first implementation. In the future it may be available up-front even while cold, but then pause on a "wait" screen while it heats up the nozzle.

[garaguido]

Yes , that is what I am talking about .... for the future ... please ?

[schirrel]

this is similar to Manual Filament Change: A New Hope #3605 dont?

[thinkyhead]

Now included as part of ADVANCED_PAUSE_FEATURE. The only thing currently missing is an option to skip unload and go straight to load, but that will be added soon.
