Hello...
I'm in building proces for my 1st printer. For electronics I just ordered Sanguinololu V1.3B. But there are some bugs/mods proposed.
Sadly I can't find board layout (or gerbers) for that board.
I know that backfeeding USB with 5V is bad idea, and this should be solved.
But for heated bed and extruder there are just two pins on connector. I don't think that can carry 10A+ for hotbed. And there are some SMT mosfet with (for me) unknown marking 7R030/PE/407 B5/9868 And don't know if that can carry 10A without overheating too.
Does someone realy run bed heater from that board directly? What mosfet is this? RdsON?
Thanks.
