The simplest way to do it is a cross drive shaft linking both sides and slave two axes together. Can't get out of synch even if one motor quits. Same concept the V-22 Osprey uses to keep both rotors turning in synch. Why fiddle with a finicky electronic/software method when a dead simple piece of metal will work and won't fail? That's my plan for a plasma table if the place in Texas the electronics were ordered from will get off their arse and get it shipped. ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
