GPOST: How to call back last A position?

[marker4x4]

Hi all how are you...


It's Friday and here I am scratching my head... I'm working on a 5-axis post for OKUMA mill (double trunnion table) and most of it works really well, except the following:


The A axis (+120 , -20 deg range) on this machine autoamtically returns to A Zero upon every tool change in order to avoid crashes. That's very cool, but if Ihave the two consecutive tools using the same A angle (e.g. spot drill and drill), I want the GPOST to call back the last known A position and output is right after my first XY movement. I've got the GPOST set as pictured, but it doesn't recall the A at all. I guess I'll need the FIL macro... Any advice will be appreciated.

You will need to address that in the FIL. You can capture the A address @ tool change. You'll need to turn on a flag to enable manipulating the goto in the FIL.


I have pointed you in the direction in how to do it. If you are new to using the FIL, it's well worth the time to read the books and learn it. If not, you could send me yourpost and I could do it for you..


CIMFIL/ON,LOADTL


capture A axis value


Save Value


turn on goto section


Cimfil/off


CIMFIL/ON,5 (goto section)


post out xy move


post out A rotation with saved value


turn off goto section


CIMFIL/OFF

Thanks Graberic. Would I be stretching your kindness by asking you to post a sample of such macro?





Thanks!!
