Hi I am working with dual extrusion set-up.
I found from LCD you can't change active extruder, so I mod Marlin to allow manual extrusion (E0 or E1) from LCD.
Dual Extrusion.
Marlin 1.0.2 Modification for change active extruder from LCD.
It`s very simple.
Open Marlin on Arduino IDE.
Search UltraLCD.h
Add this two lines:
MENU_ITEM(gcode, "Activar E0", PSTR("T0"));
MENU_ITEM(gcode, "Activar E1", PSTR("T1"));
I added before this line:
MENU_ITEM(gcode, MSG_DISABLE_STEPPERS, PSTR("M84"));
After this mod you can choose active extruder E0 or E1 and move it from Move Menu>1 mm (0.1 mm)>Extruder
I love OpenSource.
I hope you find this useful.
