I looked for the 180 ohm resistor everywhere and once I found out it was optional I left it out. Strangely, I had the exact same capacitor numbering as you (including two seperate 100n's). I do not have a cap meter and thus tried to indentify by comparing sizes. I plan on borrowing a cap meter from a friend before powering the board up. And lastly, I too spent a ridiculous amount of time trying to figure out if the unlabeled pads were suppsoed to be populated. In the end I left them alone as I saw a pic of the controller in various places with these pads unpopulated. I have built all the other components save the motherboard, and they all went much smoother. Anyways, thanks for the write-ups as they proved useful for me (shaving off the tabs in the comm jacks was clutch).

I figured I'd just move the tip faster relative to the rate of extrusion. Brad — are you thinking closer to 90° and use the tip to squish it flat?

I figured I’d just move the tip faster relative to the rate of extrusion.
