Describe your issue:

I like to run two regular endstops on my dual Z drive axes IDEX printer.

I connected the endstops to the GPIO of the raspi.

The BLTouch is mounted to [extruder] (the left one, in difference to [extruder1] on the right side)

I like to use the BLTouch to create the bed mesh.

I there a way to say Klipper that the BLtouch is mounted to [extruder] as it was formerly done by endstop_pin: probe:z_virtual_endstop in the [extruder] section.

It appears that Klipper assumes the BLTouch to be mounted to [extruder].

Everything works as expected.
