Hmm, nice suggestions.
- One thing I should have told you about the board design: it's dual sided, so the power traces for the heated bed are also placed on both sides. According to my calculations, a 48mil trace should be able to carry 5-6Amps without heating up too much. So my dual sided construction should be able to transfer at least around 10Amps without getting into trouble. But this is something which needs to be tested.
- The diode on the 7805 is a nice suggestion, I will add it in the next version.
- The automotive fuses are also a nice thing to test. I have a couple of these on my desk since I like to work on my two oldtimer cars.
I have ordered 10 boards for testing purposes. I will check the basic functions, but in the meantime I keep working perfecting the v6 board. So any suggestions and/or comments are welcome!
