Nothing is working. I tried flashing the 16u2 and it will not communicate. I am getting an invalid device signature error. I also tried flashing Marlin to the 2560 using the other isp headers and got the same error. Nothing on the board will communicate with the computer.

Do you know what code I need to type in avrdude for flashing with Arduino uno?

Can you label what each of these pins are for me please? I will be using jumpers to do this and need to know what the individual pins are.

I have done all of those things. can you give me instructions on how to burn it with an Arduino uno?

When I plug the USB to the board, it gets power but will not connect to the computer. I have the jumper in the correct place. I tried using the USB pins instead of the plug and that did not work either.

Please kindly try this.
