Why the insistence on a servo? A stepper would be cheaper and, unless I'm missing something, suitable. It is probably heresy on the LinuxCNC list but why not use an Arduino + Gecko or maybe a ClearPath? There is ample Arduino sample code showing how to control a stepper and display settings on a LCD. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
