I recently got a three axis DRO from Ebay. The Z axis either is preoccupied and won't read the scale, or it is simply broken. Since I just got it and have never seen it work properly, I'm not sure which? Posting this in the hopes someone can look at the output and recognize what is happening and advise me. The scale is working properly, as are the other 2 axis. Any advice is appreciated. Thank you very much!!
