I 'd like to use this board for my delta printer, so i need to use all 3 X/Y/Z endstop detection pins. But also i want to use BL Touch. I think it is possible to wire signal (which is normaly wired to Z-min) wire to signal pin in AC-DET, but i can't find some pin name/alias in board pinouts in Marlin Firmware to configure it.
V5, gnd and SERVO is wired from Probe pins, for remaining ground and signal I'd like to use pins from AC-DET pins.
Can someone please help with finding this pinout?
