One way could be for the host to pulse the x and y step pins in synchronism at a suitable multiple of the steps needed for the longer run. If we need a slope of 0.16666666667, then tell one smart controller to divide by 1, the other by 6. Even pi can be approximated to 1 part in ten million by 355/113, so a bit of smarts in the host could keep the axis controllers simple yet flexible, I figure. Motion commands could be sent on RS485 serial, before the primary step sequence begins. Erik (Who hasn't read the whole thread, unfortunately. There's a 1 foot diameter branch down in the front garden, and it needs to go before its ute-load of eucalyptus leaves dries to a pyromaniac's dream.) _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
