Personally, I like to have a buffer (74ACT244) () at the parallel port with a short cable to a board or boards with the isolation and signal conditioning that is needed for the particular circuit in question. I just got one of these: http://www.cnc4pc.com/Store/osc/product_info.php?cPath=33&products_id=45 (Short URL) http://preview.alturl.com/bj3t because it looks to be pretty close to what I like, except it won't plug onto a parallel port connector, which means another short cable. Most break out boards try to be generic and this tends to lead the user into thinking that all that needs to be done is plug it in and go. It really helps to understand the electronics needed for the application. Generic boards only work well if you copy the the generic machine they where designed for. If you just want a CNC machine to make parts, I think it is better to copy an existing design. If need a custom machine, you really need to get your hands and mind dirty. As far as oil and beer, I'll use whatever is handy or free. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.
