    Limit switch and Mach3

    Hi everybody. I have installed limit switches on my CNC machine. When, suppose, the Y axis hit it, it switches off the motor and Reset is flashing on Mach3. Now i want the motor to turn back for re-switch on the limit switch. How should it be done to re-switch the machine?
    Thanks.

    Navigate to Mach's "Setting" screen, and click on Auto Limit Over ride to enable it. This will allow you to click the Reset button on the main Program screen in Mach, then manually jog the axis to back off of the limit switch. Just make sure you jog in the correct direction. (If you hit the Y + limit, jog the Y axis in the negative direction to move off of the limit switch).
