Turns out I didn’t fry anything!  My powered usb hub was providing too much current to the pi and it was being passed along to the Arduino which already was getting power via the ramps board’s “green plug” that has 12v going to it.

I took apart a car charger and spliced its input into the 12v power supply going to my ramps.  The 5v output is now powering my pi.  It is all working great now.  I even printed a little box to hold the old charger.  I have a pi running my 3d printer and another running my MPCNC.

I appreciate y’alls input!
