Smoothieboard not responding to M105

I am testing a smoothieboard. It only has a thermistor plugged in at T0. It connects to pronterface and responds for M114. But does not respond to M105. Should I have all my electronics plugged in to get a response for the Temperature string to appear ?

What does your config file look like ( paste to pastebin.com ) ?

I loaded the firmware.bin file directly onto the SD card. I am not sure how to open the config file. Could you direct me? Am not able to find them in the documentation

Hello,
See documentation in detail, Configuring smoothie
This is a text file for me under windows I use write.exe good luck

Your configuration file should be on your SDcard.

See http://smoothieware.org/configuring-smoothie for information.

Thanks for the response. I got this smoothieboard from a friend and it did not have a microsd in it. So I downloaded the bin file from Smoothie-edge.bin

Uploaded the firmware.bin file on the sd. loaded it onto the smoothie and usb powered it. The sd automatically flashed and the bin file turned into cur file.

I then created a config file from ConfigSamples > Smoothieboard > config
Made one change in the thermistor pin 2.7 to nc : Here is my conifg override file -> pastebin.com / Eeh1r4q8

I uploaded this file on SD card, connected to smoothie via Simplify3D and used load [file] command to override this config file.

Let me know if this is correct. Do I need to have a any external power source connected to make the smoothie run. I only have a thermistor hooked up to the board.

P.S. I had to strip off the http as it was not letting me post links
