FYI for those of you that want a smaller easier to use power supply to power the fans ......use a radio shack 12v 3 amp setup. I also changed out my 24v fans to 12v radio shack fans. I did this so that all the fans were the same electronically and they were cheap so if i had to replace them i could get the stuff locally. Just for reference i saved about 3" off the one side and 4" off the other side of the power supply i was using from MPJA.com for the 24v fans. I don't know about all of you but i found this to be a bit better for me. Also I would recommend the www.machinetoolcamp.com electronics engineer's package for the servo system. With everything all said and done I would do everything again because I learned enough to set up my own cnc kits or the small sieg stuff. Oh and i recommend the syilamerica mach 3 post processor for bobcad for those who are using the two softwares.
