    Taurino Power
    RAMPS 1.4 (purchased as part of RRD ultimate package)
    RRD LCD controller
    running on a 24V 400W dedicated power supply

    I have opened a ticket but received no reply, perhaps someone on the forum has experienced similar issues?

    The problem is that my steppers are not moving, holding, making any noise or indication that power is applied. I need some help troubleshooting this setup.
    As it stands:
    - Taurino Power drivers installed successfully
    - Appears as USB device
    - Uploaded RAMPS 1.4 test firmware successfully but no motor movement.
    - all LEDS blinking, HB warming up, J- Head temperature climbed dangerously to 150.
    - Uploaded marlin firmware successfully
    - Smart Controller displays temps (incorrectly), most menus work etc.
    Using Pronterface, I can connect to the Taurino, set temps Movement commands do not work, but strangely the temperature reading (Pronterface and LCD panel) immediately drops as shown http://www.flickr.com/photos/67930652@N07/9455138867/

    If you have seen this before or have any suggestions, known voltages at certain points so i can rule out damage to the Polulu Stepper Drivers etc I would be very happy to hear from you! Many thanks.

    My problem was fixed by isolating the motor drivers as the problem.

    Replaced all 5 motor drivers, the odd temperature reading drop no longer occurred and my motors are running again.
