I was trying in "n" mode with no feedback at all - it did not move either. Andy, I tried different motor on the same 7i39 channel and it moved correctly, so insufficient voltage on 7i39 outputs is not likely, but I will check tomorrow morning again. -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
