Googleing stepmasternc brought up some interesting links. This one: http://www.cnczone.com/forums/showthread.php?t=41957 seems to indicate that the Alegro datasheet for the chip on your board might shed some light on how to use the chip. There is a hint that you may need a buffered break-out-board on your parallel port end of the input cable, especially if you have a low voltage parallel port. You may need to get creative to get this stepper controller/driver working well. Posting some close up pictures of the board may help. The board's datasheet: http://www.machsupport.com/forum/index.php?action=dlattach;topic=1754.0;attach=1234 doesn't seem to help much. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
