Re: [CAD_CAM_EDM_DRO] Re: Servo drives- Mariss

I have used the current version of the Rutex drives and they work well.
Tuning is slightly more difficult as there are 3 pots to tweak instead
of 2. However once tuned they seem to have less following error and
overshoot than the Gecko drives. The difference isn't huge but it is
noticeable.

They have had SPI since long before the G200x project was even thought
of. SPI is a nice idea, it is a pity no-one has written anything to run
them in that mode. As the load on the computer is much less you can have
very high effective pulse rates without any need for pulse multiplyers.
