I recently changed my controller card back to the to the Azteeg X3. I previously switched to the Arduino mega 2560, though a mosfet burnt out so back to the original board.
my question is when I hook up the power supply (12v 30amp -- not the atx version - which I think was the root of a lot of problems power wise) should I combine the two positive 12v and the grounds? On the Arduino mega the power was fine in running a single extruder with heatbed. On the Azteeg X3 the single 12v connection can not power the extruder and heatbed.
I don't want to test this out without know if this is the proper move to make, it seems this could easily burn out the power supply or the board if I do something wrong. I did look over various images of peoples setups that I thought would give some insight, but did not find any documentation or pictures of people combining the two power lines. I guess I am wondering because the mega 2560 connects both 12v lines in two separate terminals. I am not the best at electricity, so I am guessing at that point I would have 24v at 30amp (amps not changing, but the voltage would increase). Eventually I need to also incorporate back in the Viki LCD, but there is not enough power as is for now.
Here is one of the best examples I found where they are powering dual extruders, heatbed, and stepper motors with dual z-axis. [

Though they only are using the one 12v rail.
