It might be in the documentation on the CD, being so close to having my WRAPS working I'd rather not mess anything up at this point. The mechanical construction is done, although I have the box turned on edge so the PC board will mount sideways, I can work with that. The elevation and azimuth motions are centered up and move quietly and freely (about 22mA each motor operating continuously with no load at 9V). The XBee modules files have been uploaded, but I haven't taken mounted one on the WRAPS board yet, as I haven't done any further configuration to the modules. Are there changes that need to be made to the XBee module files before installing them on the WRAPS board? Are there things I should check or look for before final assembly and testing?
