A couple of months ago a new guy was hired as a "machinist" for my team. The first thing that I wanted to know was if he could adjust to Mach after working with a more "commercial" type of cnc. The 1st assignment that I gave him was to familiarize himself with the mill. I gave him the manual and told him to try some things. The next afternoon he quit with no explanation. My mill has not been the same since. Motors were out of tune Homing didn't work. I must have suffered from an enormous brain fart because I didn't retain a backup copy of the xml file. (Please don't rub it in, as I plan to burn the xml to a disc with a backup on the network.) I went into the xml backup folder and all the contents were gone. Empty. After spending the next hour swearing and beating my self up, I began the process of retuning. I got ALMOST everything done I still have a problem with the X axis. It seems to run fine during normal operation, but when I try to jog it, it growls, stalls, and when I attempt to reverse direction it tries to go in the same direction that I was going into previously. At times it faults and then I have to power down to reset it. HELP!!!!! I have tried and tried to retune it but nothing seems to work. Any ideas??
