Change default extruder

[Mate_Bokodi]

What is the problem?

We have a 3D printer with 2 extruders. T0 is the default, T1 is the secondary extruder. I want to set T1 to be the default if G-code file does not have T0 or T1 code.

What did you already try to solve it?

Checked the settings, searched for plugins, googled.

This sounds to me like something that should be dealt with in the slicer, if the slicer is properly configured then it will not have an issue.

You could add a T1 command to the start gcode in OctoPrint, then if there is nothing set in the gcode file it won't be changed.
