G-Code to run upon successful connection to a printer. This can be useful to set settings specific to a given printer. For instance, for S3G printers it is used to tell the printer the steps per mm for each axis and the homing offset.

NOTE: All Custom G-Code is subject to filtering rules.

This code is normally not inserted when exporting G-Code files, however it is processed when exporting X3G files.


All G-Code must be uppercase to function properly.



In this example, the printer will home (G28) when MatterControl makes a successful connection.
