Re: Transformers and gecko drives

Hello,

Mariss has written that it's an advantage to have all three drives on
one supply. Because the drive that is not moving can absorb the
excess energy from one that is decellerating... Based on that, I'd
say if yo can do it with one transformer, you should.

Hope this helps,

Ballendo
