Cannot configure toolhead pin on board

[pandamime100hp]

I've built the ERCF using an Easy BRD 1.1 but I cannot find the pin that uses the "Extra" pin header on the board. The config shows the pin for SKR 1.4 but documents say I can use the "Extra" header.

My current settings. I have tried cycling through different pin numbers but no luck.

1/ Change the gear_stepper's endstop_pin to an unused but existing pin on the Seeeduino XIAO, PA1 for instance. 2/ Put the jumper on the board between 1* and PA7 3/ The pin to set for the extra connector is now ^ercf:PA7

Thanks for the help @Tircown.

It didn't help however, Mainsail indicates that the toolhead_sensor is 'detected' but there is no filament at the sensor. I fed some filament in but nothing appears to change. Is there something else I can try?

Should the indicator change as soon as I feed the filament in or does it change if I refresh the page?

The issue is now related to the toolhead sensor itself. This may be due to the wires, the strength of the magnet, etc. Voron's discord server, #ercf_questions is a better place to get help.
