Do you have the user manual for the DM542? If not look at the top top half of page 9 here https://www.omc-stepperonline.com/download/DM542T.pdf It tells you things like how long you need to hold the "DIR" pin before the next step pulse and the minimum pulse widths. I'd make them all larger than needed by about 4X because you are not trying to make these go fast. In fact, a 50% duty cycle square wave works fine. What you do is in the loop when you set a pin high you store the time for when it must be set low and every time through the loop you do whatever has a time-to-do that is expired. You can juggle N balls at once in one loop this way. -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
