I want to assign a pin from the board to the SSR that when in start to print i will a commang in the gcode to get that pin to high so the ssr will turn on the lamp and add a code to the end gcode to turn it of.

Is there a free pin for mr to use? and how can I use it?

There are free pins to use. My suggestion is to use the case light. Discussion on finding it and using it can be found here:

thanks but I am using .91 software

There is GCODE to switch the pins on and off. You just have to find the pin.
