 The motherboard for the D6 was "heavily inspired" by the

+It is based on the ATMega2560 microcontroller. It is primarily a 24 Volt circuit, with some 5 Volt pins.
- It is also based on ATMega2560. As with almost all components of the D6, it is primarily 24 Volts.

+==== Interesting Pins ====
+   * J9 - Have heard of it being used for Z-probe purposes, [need more info]
    * J19 - Here a 2pin JST Female connector was added to J19 for easier connection. Highly recommended!
    * J16 + J17 - Does anyone know what these (Safety 1+2) would or could be used for?

 ===== The Relay =====
+A common point of failure in this version of the motherboard is the 5V circuit relay (Big Blue Cube). It can cause many issues where the printer "sorta" turns on, because the relay turns off the 5V circuit, which is the front panel interface LCD and knob.
-Due to the design of the motherboard being "extremely inspired" from the Ultimaker2 motherboard, there are certain issues that come up. The relay (blue cube on motherboard) serves no purpose and will sometimes cause problems.
 TL;DR: Bypass the relay by shorting it with a solid core wire to fix MANY issues. See my terrible soldering job below that works just fine!
