A number of the motor manufacturers Galil, Kollmorgen, et al have motor sizing information information and tools on their web pages that may be useful. I just had to lookup the Kollmorgen page to make certain that I'd spelled that correctly so here is a link for them.
http://www.kollmorgen.com/en-us/service-and-support/technical/technical-support/ OK, here's Galil's: http://www.galil.com/learn/motorsizer I've been working on retrofitting an old dish antenna system, see < https://www.youtube.com/watch?v=HqAmpVnAuzE> with Galil products with good luck. However, just for the record that is not using LinuxCNC. - Wayde -------------------------------------------------------- On Wed, Jan 13, 2016 at 9:52 AM, Bruce Layne <linux...@thinkingdevices.com> wrote: > I've had good luck with the stepper kits for CNC conversion on eBay, > from Wantai or Wantmotor or Longs Motors.
