    Re: Simulator crashing Rhino

    Simulator crashing Rhino

    Using commercial licenses for Rhino 5 SR14 with madCam 5 3 axis 2017.1019. Everytime I click on the simulator icon Rhino crashes. Everything else seems to work fine. Any ideas?

    Thanks.

    There's definitely something else going on there that's not related to belt drive per se. Loose belt, weak stepper motor, low power supply would be my first three guesses. Hope you figure it out.
