Well that is interesting. I have a new board on the way, ordered it two days ago. And the board was not soldered by myself, but that one copper joint that burnt I did re-solder. But the board was just fried, bubbling on the silkscreen and such. But I have a new ramps on the way along with a couple new heater cartridges.

That's what happened, the heater cartridge fused the connections and caused a very bad short it seems.by Redledr - Delta Machines
Well I just got home and went and looked. The Mega board is perfectly fine, powers up and resets. I took the ramps shield off and the D10 MOSFET connection on the back are toast. And the heat cartridge was twisted and the wires fused at the base. So I found my problem!by Redledr - Delta Machines
That sounds more reasonable, I was moving around the hot end and the wires could have broke and grounded to the end block. I'll check when I get home and see what I'm pulling. Is it normal for hot end cartridges to short out board or short out period? I wouldn't think something so small could be the straw that breaks the camels back, or in this case the PSU. But say it did, and the wires are nowby Redledr - Delta Machines
So yesterday I got my kossel up and running. 450W ATX PSU, I have been using that power supply to make dry runs on the kossel for about a week, waiting for all my extruder parts to arrive. Anyways, I am so green to the whole delta printer scene. I was printing yesterday with filament for the first time, but not the first time I have had a dry run with a heated hotend. First print went great, secoby Redledr - Delta Machines
