With dependable tool changes on a HNC. the stop latch (under the cover on the operator side of the carrage) is usually the thing to get right.Adjustments are made by removing the long black cover on the right side of the carrage.Under here there is a round plug with a hex socket,BUT remember to loosen the lock set screw that comes down from the top. If the turret works once or twice correctly then your problem is more than likely mechanical rather than computer related. A combination of the magnetic sensor and the stop cushion is more than likely the issue. What I do if I had to remove the sensor for some reason is try to get the turret to work as best as you can without the stop cushion(just to make sure the sensor is very close to working) then fine tune with the stop cushion. It takes a little while but once you get the stop working correctly the turret will be 100 percent reliable Terry

I have an HNC that I successfully retrofitted. All works fabulously, except for a running fight with the turret. It will work perfectly one day, and fail to latch repeatedly the next. If it were reliable, this could be a production machine. Any advice? If I were a bit more clever, I could rewrite the ladder to fail more gracefully and mitigate this problem. Perhaps I should be asking for ladder configs to study. Currently I am using one that Radek was kind enough to copy for me, but in all my fooling with it I may have made changes.
