Possible broken board, how to test  

Possible broken board, how to test

Hello

I have had an MK3 for the past week or so, it's been great, but..

I was just wondering if someone might be able to help me. I soldered the pins on the raspberry pi zero w and was able to get it to work with my printer correctly without a problem.

I was an idiot, however. I tried doing a similar method with the raspbery pi 3 using the same pins. I did not take into consideration the power changes, and may have inserted into the wrong pin slot a time or two...

Basically my MK3 will start up, but both the heat bed and the extruder thermistors are always on. I can tell that both the thermistors are working correctly (just on all the time), and so are the temperature gauges. The fans are fine. The LCD monitor works and is responsive. I am willing to be the X Y Z E motors are working fine as well.

I can't find anything that looks shorted out on the Einsy board (pictures are here https://imgur.com/a/BDY1m ) , but whatever controls the ON/OFF for those two pin locations is stuck in the "ON" for me...

Again any help is recommended. If there's a good way to test the Einsy that you know about, I'd love to hear it. Side note-- just plug your raspberry pi 3 in via usb.

Thank you to Prusa for making such great products by the way!
