Hi. I'm totally new in G-Code, and maybe somebody can help me.
I have a Ender-3 Pro 3D printer running Marlin 1.1.6.2 firmware. And I need to use it for a very simple task such as constanly moving Y axis couple of centimeters back and forth when it's turned on. Now I manage to do this with Terminal application by simply sending gcode commands to it. So my question is - maybe therese is a way to use some kind of macro to loop this process? Or even put a file on sdcard so the process would start when I turn on the printer?
