Review on BIGTREETECH SKR 3 EZ Control Board 32Bit New Upgrade Silent Board Support EZ2209/ EZ5160/ EZ2130 Stepper Driver Compatible TFT Series Touch Screen, DIY For Most FDM 3D Printer (With 5PCS EZ2209) by Josh Schaefer

I really want to like this board. Setup is very easy with the TMC2209s, and support is also very good (hint: BTT's tech support email is support01@bigtree-tech.com, NOT support@bigtree-tech.com). Unfortunately, my 4TH BOARD is malfunctioning.Here's the breakdown:1st) Dead on arrival, also killed all of the drivers and almost killed my laptop (probably a 3.3V short per BTT support).2nd) All 12V Fan pins dead (everything else seems to work)3rd) Worked for about a month before a short somewhere blew the onboard 10A SMD fuse. I thought it was a short in my heating element, except I have that running through a relay.Like I said, fantastic board when it works, but I don't think anyone should have to buy 5 boards (maybe more?) to find one that works.4th) Same as #2
