There are dozens of examples of this on the mach yahoo group and on the
machsupport forum. Usually the A axis is used to rotate the turret. Some
have used modbus or PLC devices to control various lock pins and
indicator switches. There are several sample macros on the forum.

I am just starting a turret for the Emco5-PC I bought at Cabin Fever.
