Release power to stepper motor I'm driving a large stepper motor via a GeckoBoard G213V and arduino UNO and I have that mostly working fine. However, I'd like to 'release' the stepper so it can swing freely.

There's two reasons I want to do this:

1) (Most important) I want the rotated object to naturally swing back to the 0 position thanks to gravity.
2) The motor gets hot - I'd rather not juice it when it should just be sat at 0.

Anybody know how I can do this? I'm using the AccelStepper library so a solution compatible with that would be ideal.
From the documentation:


  TERMINAL 7 Disable
  This terminal will force the winding currents to zero when tied to the step and direction controller +5V.
  
  The DISABLE input on the G213V is optically isolated and requires logic “1” to DISABLE and logic “0” to ENABLE the drive. Once it is disabled, the motor windings are unergenized[sic] and the motor freewheels. (emphasis mine)


So, feed the disable input a high.
