I was trying to diagnose why my extruder was not heating up by testing the voltage across the thermistor and D9 and for some reason I got it in my head to test the stepper drivers. I placed the multimeter across a stepper driver on the actual device itself not on the header,this resulted in the hotbed LED shutting off. I disconnected all the PSU and the Arduino immediately. I replugged the Arduino to my computer connected to pronterface and it seemed to work until I turned on the PSU. The printer no longer recognizes the Arduino and I get "usb not recognized"
I'm using an ATX switching Power supply @ 12 V and .8 A.
What I've tried:
-Unplugging all the stepper drivers
When I did this for some reason I smelled a burning. To which I immediately unplugged everything. I felt around the Arduino and RAMPS nothing was remotely hot.
Any idea what I did/how I can fix it?
