Update 08/10 : Fixed SD card / Corner level configuration Update 08/10 : forgot to define SD card support. i will fix as soon as possible ... sorry This is my version of Marlin 2.0 (6 october version) for Geetech A10 with dual extruder and single nozzle (all A4988 steppers). There is two way to use single nozzle with dual extruder in marlin configuration. Dual extruder You can use mixing colors (this is Geetech Choice for A10M or A20M). This solution is not easy to use with slicers (Slic3r, repetier or else). But in this case you can mix colors. (this is enabled with #define MIXING_EXTRUDER in configuration.h) OR you can use singlenozzle with dual extruders. Easy to use with slicers but no mixing colors. (Enable with #define SINGLENOZZLE and #define EXTRUDERS 2) I prefer solution 2 and this is my choice in my marlin version firmware. BLtouch Normaly after a G28 the bed leveling and you must do again a bed level (G29) or use M420 S1 to restore bed leveling ON. With #define RESTORE_LEVELING_AFTER_G28, you restore Bed level automatically But when you power up and do a homing (G28) , the bed leveling stays OFF. Then you must enable bed leveling ON by LCD menu after first G28. Or if you prefer In your Printer Gcode slicer you must begin with G28 (home) M420 S1 (enable Bed level ON) Features : i enable softwate PMW for fan nozzle. i enable buzzer i enable Individual homing. i enable software endstops ON/OFF by LCD Menu (useful for configuration nozzle Offset) LCD prusa Style Uploaded with Arduino 1.8.10... i don't use Atom or Visual Basic code I you want to use this firmware with A10M or A20M. You must change steps for extruders (and bed size for A20M)
