The T0 T1 and T2 connectors are for thermistors which allow you to measure temperature. They aren't needed for the cerambot.
The limit switches should be connected to the pins 2 4 6 of the end stops block of connectors starting from the left with the green connectors to power on the left as you look at the board.
2 - x endstop
4 - y endstop
6 - z endstop
You can verify that they are connected and working properly by using a program called pronterface from http://www.pronterface.com and connecting to your printer then sending it the command M119. If everything is correct you should get the following:
Send: M119
Recv: Reporting endstop status
Recv: x_max: TRIGGERED
Recv: y_max: TRIGGERED
Recv: z_min: open
Recv: ok

So, I downloaded Pronterface. I have it plugged into my printer and I've selected the correct COM Port and sent the code M119 and it says "[Error] Printer is not online"

I tried pushing the "connect" button and got the following:
"Connecting...

I had similar error until I used 250000 as my baud rate.
I'm seeing this though once I did connect.
Connecting...

Printer is now online.

This is what I'm getting from the M119 Command.
SENDING:M119
Reporting endstop status
x_max: open
y_max: open
z_min: TRIGGERED
z_max: open
Not the same as yours. How do I go about fixing this?
Are my limit switches wired incorrectly?
