Geckodrive recommend the following, for unregulated supplies it's

C = (8000 * I) /V where C is capacitance in uF and where I is amps
and V is volts

For Linear or Regulated supplies 2000 to 10000uF.

Caps need to be at least 20% higher in voltage rating than max voltage.

I've always stuck to that and never had a problem.

All the information needed is on their support pages.
