I have drooled over that stepper board Jon, but at that price & my budget, stepper pulse generation in software is my future till I fall over. I cry in my evening bottle of Ultra Lite about it from time to time, but the bottom line is that so far it has gotten the job done. Perhaps not as pretty, but usable results nonetheless. > ------------------------------------------------------------------------ > ------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, > more!
