Controlling Power Supply with SSR

I've got a SSR hooked up to my power supply and would like to use the M80/M81 commands to turn it on and off.

I've got the "on" part working, but when it tell it to switch "off", the SSR coil continues to get voltage.

I'm using the Sanguinololu's common 5v and expansion pin A4 as ground (and the on/off). I'm assuming I'm doing this wrong.

Anyone have ideas?

Answered my own question. I had to change the code in Sprinter to make it act like an High/Low input instead of an output.

Basically copied over the code from the FAN_PIN (M106/M107) and changed PS_ON_PIN (M80/M81).
