I have little doubt about the 7i49 working better, but it has six channels and I may need a single motor or stand alone solution. I will have screw encoders for table position, so I just need commutation sensors. I haven't fully researched the problem yet, but if an Arduino or more likely an AVR solution is possible at $15 - $25 per motor, it might be worth getting the motors. Another option is to add Hall sensors and not use the resolver, or just not get the motors. The more I think about it, adding Halls seems to be the way to go. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
