I was running parts, 2 done 4 to go, After 3rd piece was put in chuck, I pushed start and walked away. I came back expecting a finished part and machine was just sitting there with the spindle turning (looked a little slow) doing nothing. error on screen was # 9208 " spindle not in set range" All I can find on this error is to check the G26 and G92 set points. G26 = 4600 and G92 is at 1500. Machine should have been at 363 RPM and it was showing 212. Power off - reboot, same thing. I cannot find anything on spindle speed calibration or any trouble shooting on this error. HELP.
