Both the endstop hit AND the g28 behaviour are solved.\r\n\r\nBasically with EXTERNAL_Z_ENDSTOP_INVERTING true to false set to false you can do normal homing and movement. But when you add the probe hardware to thesecure_sw port the behaviour is the same as before.\r\n\r\nthe opposite happens if you set EXTERNAL_Z_ENDSTOP_INVERTING to true:\r\nwith the probe it works correctly, without it does not!\r\n\r\nNote that if you run a g28 and it hits the z_max endstop it will somehow fix the port status back to normal in both cases.\r\nAnother option is to have EXTERNAL_Z_ENDSTOP_INVERTING set to false and set it to true once the functionality has been enabled via gcode (M746 S1 sets it to true, M741 S0 sets it to false).\r\n\r\n"}}
