I am building a dual x carriage 3D printer and using the Marlin firmware 1.0.x to setup. But the lcd menu tree can only control X Y Z and one extruder E I want to add X2 and E2 in the Menu Prepare -> Move Axis, so I can manually move the second carriage and extruder So far I have looked into the Ultralcd.cpp file and add the following line: static void lcd_move_x2() { _lcd_move(PSTR("X2"), X_AXIS, X_MIN_POS, X_MAX_POS); } MENU_ITEM(submenu, MSG_MOVE_X2, lcd_move_x2); This adds another line in the lcd and shows the X2 option however it only moves the first carriage X1 I think the problem is that I should not use the X_AXIS in the code, but I dont know what command should I use. How should I define something like X2_AXIS so that I can control X2 https://reprap.org/forum/read.php?1,777623,777623#msg-777623 Fri, 11 Sep 2026 21:29:54 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,777623,835175#msg-835175 https://reprap.org/forum/read.php?1,777623,835175#msg-835175 datesheet General Mon, 01 Oct 2018 12:56:28 -0400 https://reprap.org/forum/read.php?1,777623,805980#msg-805980 https://reprap.org/forum/read.php?1,777623,805980#msg-805980 3DLTech General Wed, 17 Jan 2018 14:57:09 -0500 https://reprap.org/forum/read.php?1,777623,777623#msg-777623 https://reprap.org/forum/read.php?1,777623,777623#msg-777623 But the lcd menu tree can only control X Y Z and one extruder E

static void lcd_move_x2() { _lcd_move(PSTR("X2"), X_AXIS, X_MIN_POS, X_MAX_POS); }

MENU_ITEM(submenu, MSG_MOVE_X2, lcd_move_x2);
