Hi,
I can say for sure what made the motors run so much smoother and quieter, but it was a welcome outcome. Replacing the Gekco 202's with the Gekco 203V's helped I am sure.

Hi,
I installed the second parallel port card and it works great. I have also made a dual outlet box that has 3 solid state relays installed. I removed the connector tab on one of the receptacles so that each of the two outlets could be controlled by a separate solid state relay. My current Mach3 screenset will allow me to click on an icon and toggle my dust collector and vacuum pump on and off. I still have one spare that can be used for another device.
Here is a link that shows the solid state relays that I used. They are rated at 25 amps.

Hi John,
Even though you look like you're finished with your relay box, this is a nice writeup that adds some nice features.
