If your stepper drivers have enable inputs, then you would hook them up to the breakout board outputs. You would also need to connect the enable signals to the breakout board in your .hal file. There should be some lines similar to this: "... # connect enable signals for step generators net Xen axis.0.amp-enable-out => stepgen.0.enable parport.0.pin-01-out net Yen axis.1.amp-enable-out => stepgen.1.enable parport.0.pin-06-out net Zen axis.2.amp-enable-out => stepgen.2.enable parport.0.pin-16-out # connect signals to step pulse generator outputs net XphaseA stepgen.0.phase-A => parport.0.pin-02-out ... " Your lines with parport.N.pin-XX-out will need to match the pins on your breakout board. The enables go ON when the machine on button is pressed to ON. This can help keep your axes from moving until it is safe, but in order to do this properly you need to have a charge-pump watchdog to keep the enables off while the PC is booting. Or, as you found out, you could do without the enables and leave the drivers active all of the time. You'll need to figure out what your needs are. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Forrester recently released a report on the Return on Investment (ROI) of Google Apps.
