However I find it odd that you would have two blown drivers happen at the same time.

it will most likely be to mechanical parts or the wiring

That's what I was thinking, strange how they're both not working.
The Davinci wiring connectors are not the greatest, particularly the black extruder heater connectors.
They caused me a lot of trouble so I replaced them with these .... http://www.ebay.co.uk/itm/281708720820? … EBIDX%3AIT
They form a rock solid connection that won't fail no matter how much abuse you subject them to.

first is the hot end heating up? 
if its not heating up the stepper motors will not advance the filament. so if its not heating up check the heating carts connections and possibly the 0 Ohm resisters that are used as fuses

if the hot end is heating up then next thing to check would be the wiring. 
Since they move around during printing eventually you will get a break in the wires.

next check the mechanical you may need to heat up the hot end and manually remove the filament to do this. once you are sure that the inspected parts are not to worn and are working correctly obviously replacing anything that needs replacing and lubing anything that needs to be lubed. if its still not working then its time to move on to the electrical

you will then need to inspect the wires for a break. a continuity meter is good to use for this. If the wires are ok then it could be a blown stepper driver.
