I am using Arduino DUO's to run three stepper motors - same code on all three. Can I use a single power supply like the MEAN WELL MDR-60-12 AC to DC DIN-Rail Power Supply 12V 5 Amp 60W to power all three Arduino's via their VIN pin? Can the grounds be shared between the three Arduinios?
Got a link to that?

Yes, you can power three devices from one power supply (and share the grounds).
Remember that an Arduino is not a power supply, so you basically can't power anything from the 5V or 3.3V pin.
Why three DUO, can't one DUO do all 3 steppers?
What are the specs of the steppers and drivers?
