My guess is a $20 Arduino like board: http://www.sparkfun.com/products/9219 and a $15 PCI dual parallel port card, could make for a fast 3-axis (or more) step/dir setup. Add another Arduino for servo feedback, all in real-time, fully open and user configurable, and well integrated with EMC2. But I won't really know until I actually make one. It could be a Chipsduino. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.
