I have attached a 14cfm compressor to the spindle, I'm getting a not enough pressure alarm during a tool change on a linear magazine. After a tool holder is released, a large volume of air continues to escape from the spindle nose, and the alarm is activated before it can get the next tool. Any ideas please? If I manually release a tool holder by presing F2 it releases the tool and there is no continued pressure loss. It seems like when performing an automated change the tool release is permanent.
