hey guys......new to okuma mills and had a wierd thing happen.....the tool changer went random. i was at tool 19 in the spindle ( always a drill chuck) loaded tools in through the side when i called up T1 via mdi (T1M6) to start gaging tools and the machine put T19 in T14 slot and gave me T7 instead of T1??
im pretty new to okumas ( 8yr. Haas guy) ..........what could have happened? no one at my shop knows why this happened but insists that it only happens when "new guys" are on it. (go figure)

Thanks in advance- Joey
