weird power on spinneret

I was wondering if anyone had the same issue as me. I plugged mine in then it turned on for a split second and got really hot then turned off. I just ordered a new web server got it on friday and decided to power it up. I have an adjustable power supply that goes from less than a volt to 24 volts with a digital read out on the front. I read the documentation before hand and it said anywhere from 3-3.6 correct? Also you can use a different setup for from 4 to 9 v right?. Set my adjustable psu to 3v at 200 Mah's because idle is uses 175 Mahs.
I guess what I am getting at is, there anyone that has had a power problem with theirs where it just stops working and gets really hot?

    J2 is for the Prop Plug. It's definitely not a power input. The correct way to power the Spinneret is to apply 4-6VDC to J6: +V to R, 0V to B. If you're using a daughterboard with the Spinneret, the voltage needs to be a regulated +5V. If you applied more than 3.3V to the 3.3V pin on J1, there's a good chance you've done some damage to the board.

    I have only applied 3 v the lowest it said in the documentation on J1 with it being grounded also

    The instructions in the Spinneret docs are pretty poorly stated and include one statement that's not true [edits are mine]:
    "There are three methods for powering the Spinneret Web Server, depending on the power source. To
    provide power from a 3.0 to 3.6 VDC source, use J1 and connect pin 2 to ground, and either pin 1 to
    power. For a 4.0 to 9.0 VDC supply, either use J1 and connect pin 2 to ground and pin 12 to power, or
    use J6 and connect pin 3, labeled 'B', to ground and pin 2, labeled 'R', to power. When providing power
    from a 4.0 to 9.0 VDC supply on either J1 or J6, the same voltage will be output on the corresponding pin
    of the other connector. Pin 12 of J1 will also output a regulated 3.3 VDC supply. [Not true.
    When 4-6V is applied to J6 or pin 12 of J1, pin 1 of J1 will exhibit a regulated 3.3V.    ] Make sure that any
    connected devices are tolerant of these voltages. Do not simultaneously supply power to multiple pins."

    Since you've got a variable DC supply, I would apply 5V to J6 as I outlined above.

    ha! i noticed they were poorly written also. I didnt catch what you saw. Probably because you use them way more than I have. I shall give that a try to night and hope for the best. and I would still ground it on pin 2?

    If you use J6, like I suggested, connecting the 0V lead to "B" does the ground connection.
