Everything has been going fairly smooth drip feeding and the whole machining process and then small things are happening. Starting to cut on part and the machine stops faults with a E stop button pressed and z axis fault but the tool is right by the part just as it was 30 seconds ago on the first go around. So I hit the reset button and the relay clunks in the back go to jog and take everthing home start the part again and no problems. It has happened three times in the last week. Has anyone had this problem?
