I have a 1983 Kitamura mycenter 3 with Fanuc 6m controller. I can issue a spindle speed and m03 or m04 command in MDI and machine responds. RPM gage reads whatever S**** I entered. However when I right a test code with a few moves etc it comes to the S500 M03 line, spindle turns on and program stops like it's not receiving speed obtained signal. I can hit reset, spindle stops and rest of program continues on thru. Anyone have ideas on fixing this...or even a parameter to change to eliminate the speed verify?
