Setup section

Would it be possible to add a section on how to set things up for the first time?

I'm not sure if this standard across all suppliers of the board, but when I first turned mine on it started running the motors, and this doesn't give you enough time to flash firmware before it runs carriages off the end of the axes. In order to stop this, you can swap the jumper from the standalone power to the USB power.

In addition, it might be useful to list the modifications you need to make to pins.h in Marlin in order to get dual Z drivers working. You need to add entries for the Z2 pins, AND you need to define Z_DUAL_STEPPER_DRIVERS in configuration_adv.h, which isn't immediately obvious. Likewise for dual Y drivers if appropriate, though you'd also need to disable some logic on configuration_adv.h which checks that you don't have dual Z and dual Y drivers enable, because there aren't usually enough stepper drivers.

I'm happy to do this if nobody has any objections. Niksko (talk) 16:03, 2 March 2014 (PST)

Linking

I'm just wondering if it is possible to link 2 RUMBAs together for 12 stepper drivers in total?

Or alternatively make an expansion that has that many steppers.
