Add a relay to the power supply and run some wires from the Rambo to it. :D

Sorry, I don't really have a great understanding of electronics, how would I do that? What I don't understand is, how would it turn it on and off when I type M80 or M81? Would I have to mess with the firmware? Thanks.

I purchased the supplies to mod mine but doubt if I ever find time to do it !!! The above article shows how to do it pretty easily for someone with a little mechanical and electrical skills. Hope this helps. :D

Thanks so much! That really helps! I just have one question, would I connect the relay to the ext2 pins ( labeled in the rambo datasheet)? thanks again.
