two Y motors with separate endstops



  • Hi

    I have a printer with two motors on the y axis each of them has a endstop. One of this motors and endstops connected to the duex5 E2. I have mapped the motors together in the config.

    When i homing the Y axis both motors beginn working correctly but only this on how is connected to the duet board directly is stoping when the endstop is hitted.

    The U endstop should be connected to the E0 endstop connector. Is that where you have connected it?
