I have a 21-T control. Whenever the turret tries indexing it rotates for a while and then tries to seat. It is supposed to rotate 30 degrees per tool but it does not. The encoder connected to the turret shaft seams alright though. Am also able to rotate the turret by hand setting bit 2 of K2 . It seems to be in control. Now it's like the machine forgot it needs to rotate 30 degrees. Are there any parameters for storing information on the turret or encoders?
