Did you see my edit RE: full RAMBo?
Sure
I finally got to the post office and sent it priority mail. Tracking: 9405803699300613700380
I’ve also included a small flat rate box label addressed to myself for return shipping. Please let me know WTF is going on, or more likely WTF I did to it…

Well I checked it under magnification, nothing. Gave it power, chip gets hot. It won’t flash at all. You didn’t plug in anything but the one side of the power, Lcd, and XYZ steppers? First issue with UltiMachine board out of 600 or so. interesting, I am going to keep tearing it apart until I figure it out.
I’m not sure what could cause it to be flashed by me and you a few times then die. I’ll send you an invoice for the upgrade.
