This lathe? http://coyoteden.dyndns-free.com:85/gene/emc/slides/slide_lathe1.jpg If the present control is with a potentiometer, my vote would be to start with replacing the pot with an opto-isolator on the pot V+ and wiper connection. Then feed the opto input with a parallel port pin and software PWM or PDM. If you have a faster hardware signal generator (FPGA thingy), that would be even better. I use another pair of opto-isolators for Forward and Reverse. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
