Been super busy these past few days. I will have time to update the wiki and the buy page with more info now that the last of the pre-orders went out today. I updated the wiring diagram to show the orientation of the stepper drivers.
@mhensen - thanks for answering some questions.
@Gijs - No need for special soldering equipment, a regular soldering iron will do.
@WhiteB0rd - The right angle connectors mounted on the bottom like what Luiscp did will appear cleaner compared to the top mounted. Other than that its just personal preference. The terminal block is replaced by the same headers as that of the motors, so it kinda matches the whole connector scheme. It is included in the package together with a mating connector and pins. You can still use a terminal block if you want to, like this.
