Hey guys, I'm having an intermittent problem with my Hyundai Hit8s w/siemens 840c. the spindle is not starting when the program is started. Some days it works great and then some it hardly works at all. I get no error messages, no timeout, nothing. Machine just sits, waiting for the spindle and a CSS value, I'd imagine. Siemens seems to think its a hyundai issue, and hyundai thinks its a siemens issue. Hope one of you folks can help me out. Thanks!!
