The following line creates a signal called spindle-enable, that is driven by motion.spindle-on and drives pwmgen.0.enable > net spindle-enable <= motion.spindle-on => pwmgen.0.enable > net spindle-pwm <= pwmgen.0.pwm This line tries to create another signal called spindle-on, that is driven by motion.spindle-on and drives nothing. You can't do that. > net spindle-on <= motion.spindle-on > net spindle-cw <= motion.spindle-forward > net spindle-ccw <= motion.spindle-reverse > > I want spindle-on to enable pin14 AND pwmgen.0.enable - how do I do it? You need to create one signal that is driven by motion.spindle-on and drives both pwmgen.0.pwm and parport.0.pin14. You can either name that signal spindle-enable, by editing the first line from: net spindle-enable <= motion.spindle-on => pwmgen.0.enable to: net spindle-enable <= motion.spindle-on => pwmgen.0.enable parport.0.pin-14-out My email client wrapped the above command, it should all be on one line. You can also name the signal spindle-on by removing the first line and editing the second one to be: net spindle-on motion.spindle-on pwmgen.0.enable parport.0.pin-14-out Note that the arrows are totally optional, they help a human understand the file but are ignored by EMC. I left them out of the second version so it would be shorter and not get wrapped. In general, a signal can be driven by one source, and drive as many loads as you want. Just keep adding pin names to the net line.
