  • CNC Limit Switches Frank's Workshop

    The limit switches make up a circuit to control the relay. This relay is part of the emergency stop chain. If this relay is open, there is no power to the system. The limit switches are logically chained together to form one long wire to ground. The limit switch is a SPDT switch, that is, it will complete one circuit if it is open, and a different circuit if it

  • Homing and Limits Setup and Troubleshooting ·

    Limit switches (aka end stops) may be configured to kill a job if the travel exceeds the machine dimensions. The same switches are used for limits and homing, but they are 2 different and distinct functions. So a switch can be thought of as a homing switch during a homing cycle, and a limit switch at all other times.
