Topic: Replacement Printrboard Rev E (or help ID a part on mine)
So I soldered a few headers in, mainly to get the part cooling fan. It now appears that it's broken and I don't have any idea why. It worked perfectly for a while then suddenly the cooling fan decided it was only going to open 7V instead of 12V. Measuring the voltage across the + fan pin and ground shows 12V but the voltage across what should be the ground fan pin and the actual ground shows 5V. Shortly after the USB data connection stopped working. If I short the USBPWR tabs it powers on. I'm looking to buy another Rev E as the Rev F's appear to be less featured. Thanks.
