Hi Jon,
Yes, the Geckos are one of the few drives that have electronic anti-resonace built it. The other feature that improves the performance is that they morph from 1/10 to fullstep as the stepper rpm increases. This overcomes the deficiencies of using microstepping at faster rpms, and gives you the best of both worlds.

Do these electronic techniques deliver the goods? I can tell you that the Gecko 201A from way back around 2000 were quite awesome. I have fooled around with steppers for some time, and the G201 was the first drive I would even consider for a CNC application, which since any speed can be programmed, sooner or later the resonance will bite you. The difference between typical stepper drives and the G201 is quite amazing. As far as I know, all their newer drives implement much the same scheme. I can't comment on the Parker units. > Is > a mechanical solution not needed if one or more of these electronic > solutions is employed? I've never seen resonance problems with a Gecko drive. Microstepping, user adjustable shaping of the sine waves and electronic resonance damping make the motors run so smooth they barely hum.
