Writing G-code
March 07, 2017 11:26AM
Hello,
My current setup is an arduino mega and RAMPS 1.4 with Marlin, together running 3 stepper motors. I want to use G-codes to run the motors. Could someone kindly let me know where I can write the G-codes and if the Ramps supports them if written directly in the Marlin-arduino IDE??
Looking forward for an answer.
Thank you.

Sure you can. A lot of the lcd menu options send Gcode to a serial port of the CPU. Same as Pronterface or any other printer host program does.
I'd open Marlin in ArduinoIDE and search for terms like G28, G1 etc... that will lead you to the right subroutines, where you can add/modify code to your hearts content.

Hey,
I don't seem to find any. Tried up to G40, no results.
Another doubt, If i write the Gcodes on a new window and upload them to arduino + ramps, will it work? Or should I write the code in Marlin.h file?

I made a screenshot how I found G28.
