Breathing New Life Back Into a Shopbot PRT 48 X 96 CNC Router

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.  http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=360385301485&ssPageName=ADME:L:OU:US:1123

Hi John,

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