Klipper Screen load/unload IDEX

[plain timber]

It seems like the unload macro on Klipper screen can’t be used because it’s not defined for IDEX printers.

The printhead is required to be specified but can’t be done on the screen.

I would suggest, that the homing procedure is required, and the active printhead should be the printhead which is selected on Klipper screen. This should lead to a working macro. If the homing is required must be discussed, but the active printhead should be taken from the selected one from the screen.

Can you explain what the macro does?

This replaces the load/unload macros. I used this by myself. Copy the file to you printer and add to your printer.cfg:
[include load_unload_filament.cfg]
