I haven't had a chance to look at the board due to the Melbourne heatwave. Was 31 Deg C on Monday, 41+ Deg C days since then (Today is supposed to be 44), and most nights not getting below 25 Deg C. Temp is supposed to drop tomorrow, so I'll have a look at it then.
So I thought what the heck I'd look at it now.
Only thing that I can see is a non-issue as long as we document it:
The two Due mounting holes on the Power in/FET output side of the board have ground and a +VE voltage right near the hole (one per side). IMO this is a non issue (it's been that way for ages, and same on RAMPS) but we just need to document it somewhere that under no circumstances should you use metal stand-offs/screws, otherwise you'll get a short. With the other holes you're only shorting a signal (which is still not great, but not potentially fatal to your PSU/Fuse/PCB tracks/Arduino), so it's not a problem. I only mention it because I had someone locally do exactly that with a RAMPS board, and then couldn't figure out why it wasn't working and their PSU kept tripping. Fortunately their PSU tripped and shut off every time, rather than the PTC frying itself.
I'm happy with the board as it looks, and the ground/top fill now is much more even and consistent. Noticed the mods for the pads for the 100uF filter caps too - nice!
BTW: The thermistor inputs only have "0 1 2 3" next to them. Could perhaps we also place "Therm" next to them somewhere? I'm sure someone will get confused otherwise.
