Hi all,

My Einsy RPI port is linked to an arduino (TX and RX). 

I tried to send some simple gcode like 

Serial.println("M104 S210 T0"); it work to pre heat extruder

Serial.println("M300 S440 P200"); it work to beep some sound

 

however, how do i send a gcode to select a SD file and start the print ?

I have tried 

Serial.println("M23 one.gcode");
Serial.println("M24");

The LCD show file is selected, but nothing is moving. Is there any other cmd i need to start a SD card print ?

I've not done this, so only seeing other options that you might have already found:

M32 ; Select file and start SD print
It is always wise to get more than one opinion...
