Re: wiring for 4-wire motor & Gecko drive

The gound wire is really extra. You can leave it unconnected, or put
it to either ground. It just sounds like it is for shielding the case
or providing a protective ground in case the stepper is bolted to
a chassis or whatever and the operator might touch it. This would only
be a problem if the chassis etc become 'hot' due to a frayed wire etc.
Leaving it unconnected wont affect operation.
