It doesn't have to be extremely precise. It is just so you can load the parts in a certain way. It does not have a C axis but from the messages I've gotten it seems like it is an available function, it's just finding out how to turn it on.
Open the electrical enclosure, on the inside is a list of options the machine came with.
If the machine has Spindle Orient, then is should be turned on, if not call your HFO with machine info and they will provide you the CODE to Turn it back on.
If the machine DID NOT come with Spindle Orient, there IS or WAS A TRIAL Period to see if you liked it before you Bought the Option. It's something you could turn on and off as needed till the Trial Time Period expired...or if you forgot to turn it off...it didn't take long for its usage to be up. Once that trial period is gone, its gone till purchased.
IF the Option was purchased at a later date, that OPTION wil still be active with HAAS, Call them and they will Provide the CODE to activate the Option.
If the Option was not Purchased, you now have the Option to Purchase. Credit Card, Check or put on your account they will get back to you with the Activation CODE and Procedure to turn the Option on. Usually all done with in a few minutes.
Yes, the Spindle Orient M19 works well for orienting spindle to grab with a Bar Puller or to orient spindle for shaped materials and a Bar Feeder, or to broach a Key etc. But its an Option and Needs to be Turned on with a Machine Specific Code from Haas
