Gene brought up mechanically damping mid-band resonance in a stepper. I'm old school and mechanical/inertia dampers are all I know. Folks have posted videos to YouTube that show the efficacy of this approach.
However, I've noticed a number of stepper-drive vendors claim to have electronic solutions to the resonance problem. Geckodrive, for example, has its "mid-band compensation." Parker Motion has not one but three techniques: ActiveDamping(TM), Electronic Viscosity (TM), and ABS Damping (TM). Question to y'all. Do these electronic techniques deliver the goods? Is a mechanical solution not needed if one or more of these electronic solutions is employed? (I'm stilling using the PMDX-150 drives I bought from Steve years ago. I don't want to buy a new drive just to test a vendor claim; I'd rather wait until I the magic smoke has escaped from one of mine.) Are there any videos posted that might satisfy us honorary Missourians (the Show Me state)?
