G-Code Command Directory

You can send lines of G-Code into your Pronterface UI to give manual commands to your Printrbot.  These codes can also be inserted into existing G-Code to adjust behavior during the print.

For instance, if you wanted the fan to turn on before the hot end began to go to temp, you would insert the following code to the beginning of your text file.


M106 (fan on)

M104 S210 (set extruder temperature to 210C)
