The control system was about 15k total, most of that taken up by the 5 ADC drives/servos (around 1500 per axis).
Russle said, at the Mach3 Convention SE that when all was said and done he had about 60k, since he spend ALOT on Labor, and since it was an R & D project there was alot of bug chasing both mechanically, electrically, and Motor tuning. He had bad power issues up there, I built the system for single phaze 200v power, but when I got to the site, it had Tripple Phaze and the 3rd leg was a Phantom leg, and the biggest issue was his power was NOT stable it would range from 190-243V. This played hell on the Geckos (3 or them for the minor axis, and thus they had to be upgraded to 3 ADC's since they can handle a much wider range, plus 3 phaze).
Now that he knows what he wants in a Machine, he is building a second one that has all the Mechanical changes and Upgrades, he thinks he could build another for around 30-40K.
