How to Trigger a Macro when the printer is powered on?

[sk8board]

I am using Mainsail and want to start a delayed_gcode macro timer immediately after the printer has been powered on.

Printer power switch | Mainsail

How do I automatically trigger a macro when the printer is turned on?

you can only execute a "delayed_gcode" when klipper is ready (or at least every macro can only be executed, when klipper is ready): https://www.klipper3d.org/Config_Reference.html#delayed_gcode

Thank you for your reply, as this makes sense. Would it be possible to create a Klipper startup trigger that can be used to trigger a macro immediately after Klipper becomes ready after startup?

yes. pls read the link above. you have only to add initial_duration to your delayed_gcode.
