Post question "C axis reset at tool change"

[neurosis]

I really dont need my 4th axis going back to A0 at every single tool change. What I notice though is that if I turn this off, the 4th always travels the shortest distance to the next index. Well, I am just rotating around 90 deg the same direction every time pretty soon my A value is A-540 or something like that. I guess that doesnt bother me except for the time it takes to rotate back to 0 at the end of the program. Is there a way to get the post to output a C axis init just at the end of the program? I think I can do this myself but I dont think that it would be the right way. I also want to know if there is a way around the A-540 or what if anything people do about this?

 

Thanks

You can check in your post for this

 

code:

---

frc_cinit    : yes$  #Force C axis reset at toolchange

---

change it to no$ that should stop the A0 move at every tool change
