Using 'opinfo' to store POCO grab position

[M.Bluedorn]

Hello all. This is my first posting but I've been gleaming knowledge from this forum for quite some time. So a belated thank you is due. What I'm trying to do is grab and store my POCO grab position which is param 13212, and then use that number in basically a comment at the beginning of the program. I've tried several different combinations of strategies I've learned from the MP Post Documentation and cannot get it to post anything other than the dreaded '-9999.' Any help would be greatly appreciated.

Throw up your logic attempt and see what you have laid out as a an attempt and someone should be able to guide you.

Please make sure to post up like so using the insert code so someone can see the proper spacing and such that is paramount with MP.

Part handling operations don't have tool change lines.  The lack of a tool change means that opinfo doesn't 'see' part handling operations in it's offset(default) mode.  This means that you need to read the operation stream to look at all the operations.

If you have questions about this I recommend you contact your reseller or post on CNC Software's forum.

Upon doing some digging and talking to my post guy at our Mastercam reseller, it is looking like even attempting to grab the parameter for any use at all would be not available as they have binned all of the POCO part of our paid post. I was unaware this was a thing until today while I was trying to figure this out. Needless to say I have a lot to learn still.
