Our bridgeport tc-3 with fanuc control is having an intermittent error during tool changes. The carousel will move forward, grab the tool, the spindle raises and stops, it does not turn and try to select the next tool. The error message that comes up is tool arm not back. I can jumper out the tool arm brake, push the tool carousel back, rehome the machine and run for a day or two before the error comes back. Any Idea?
