I think if I were to stick with the 5 phase motors I would go the extra yard and program a micro with the step sequence so that all that was needed is a step and direction interface.
I was just reading this web page about how much better 5 phase steppers are.. http://www.orientalmotor.com/MotionControl101/2phase-v-5phase-intro.htm It's a pretty interesting article. ----- Original Message ----- From: "Jeff Epler" <[EMAIL PROTECTED]> To: "Enhanced Machine Controller (EMC)" <emc-users@lists.sourceforge.net> Sent: Thursday, May 10, 2007 10:21 PM Subject: Re: [Emc-users] Turning tiny bits...solution? > On Thu, May 10, 2007 at 09:44:45PM -0400, Dean Hedin wrote: >> My next problem is that I have discovered that the steppers on this >> machine are 5 phase.
