We’re working with FarmBot Genesis v1.3 but without encoder cables so we’re attempting to add in endstops instead. So far we have 2 endstops (x min and y min) using simple buttons. They’re connected the the Farmduino as shown. The x endstop doesn’t work at all and the y endstop only works when connected as shown, between GND and 5V. Both gave the same result when we tested them with a multimeter and pressed the button (high resistance but becomes low when the button is pressed) so we’re not sure why only the y end stop works. We’ve also tried swapping them round to see if it’s a problem with the pins but, in any of the 6 endstop slots, only the y endstop works.
Also, the y endstop works no matter whether the y endstop is enabled or not in the device settings. When the y endstop is activated the logs read:
Firmware handler: Elixir.Farmbot.Firmware.UartHandler died: {:error, :eio}
UART handler died: {:error, :eio}
UART device removed.
and the FarmBot stops moving.
Anyone got any ideas what’s going wrong here? Why is the x endstop not working and why does it not matter whether or not it’s enabled in settings?
