It has been about 6 years since I was on this site. My machine has just been taking up space for several years. I just decided to clean the dust off. I wanted to make it bigger so I rebuilt it. I am using a RnR usb motion board. I have watched some of the videos and downloaded the xml file. I am at a loss as to how to set up the motor outputs in Mach3 (Port # and address, pins, etc.) I could use a little help from you experts. I will be using it as a router. I have installed a 1500watt spindle. I have it running off the front panel. Any help would be appreciate any help you can give.
