Dual extrusion from LCD (RAMPS1.4 - Marlin 1.0.2) 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.

This is not tested so be careful.
Keep your finger on power button while testing changes.]]> SergioMC Firmware - mainstream and related support Thu, 23 Jul 2015 02:38:21 -0400 https://reprap.org/forum/read.php?146,535580,535882#msg-535882 Re: Dual extrusion from LCD (RAMPS1.4 - Marlin 1.0.2) https://reprap.org/forum/read.php?146,535580,535882#msg-535882 Now, if I only find a way to retract faster.
It takes forever to change filament with a 500mm Bowden tube :(

My only solution so far is a hand written g-code that is permanently on my SD-card.]]> o_lampe Firmware - mainstream and related support Wed, 22 Jul 2015 12:33:05 -0400 https://reprap.org/forum/read.php?146,535580,535580#msg-535580 Dual extrusion from LCD (RAMPS1.4 - Marlin 1.0.2) https://reprap.org/forum/read.php?146,535580,535580#msg-535580 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.
