So I've got a couple problems, to begin I'm using the RAMPs 1.4, generic Arduino mega with Marlin, generic stepper motor drivers, a generic power supply. Nothing is special or even out of the ordinary. But for some reason when I plug the RAMPs in, with everything connected or everything unplugged my Arduino heats up like hell. I clocked it at around 60°c after a couple seconds of being powered on around where the main chip is. The voltage regulator seems fine because it doesn't heat up much, I've checked it around 40°c.
Second problem is the stepper motor drivers keep blowing up for some reason. With everything plugged in I power on the board for the first time and hear a small pop and then a small amount of smoke comes from the extruder driver. I replaced it thinking it was just a bad chip and the same thing happens. All other chips are fine it's just the extruder that fries.
When the board is plugged into usb it doesn't give me any readings what so ever on what the printer is doing but the Arduino works fine with anything else I throw at it.
Things I've tried: - Lower the voltage on the power supply from 12.00v to 11.26 with no changes - try running it with everything plugged in and everything unplugged - tried buying a new Arduino but the exact same problems occur
I've gotten kinda tired of thinking of ways to trouble shoot so I'll open it up to the community. Picture of a friend stepper driver
