Post File Help for C.R. Onsrud multi-spindle

[Zachary_F]

Hi, I am tasked with switching our C.R. Onsrud CNC over from using MasterCAM to using InventorCAM and am having some issues with finding a proper post file. I found another post on here that said the fanuc_31i post file should work and I tested it out. It does work, but the issue I'm having is the end of the program it does not place the tool back in the tray and return the beds to the load position. I could manually place the few lines of code needed but our intention is to join our CAM functionality with the iLogic we have created to automate assembly and part configurations. The issue I think with the post is due to our machine being a multi-spindle C-series which has two individual beds and spindles. Any help or guidance would be appreciated!

If anyone reads this, after must time and many revisions I was able to modify the original post file from Autodesk to work on my CNC machine.

I hope anyone else that needs it can use it. The original post file "CR Onsrud 5-axis Router with Fanuc 31i control" worked on my machine but it did not allow for the slaving mode that is available on the dual spindle C-Series machines. It also would not put the table to the load position at the end of the program and return the tools to their tray. My post file is able to achieve this. I am not a post wizard so I don't know if it will work for any other types of machines. It does work well on mine though with InventorCAM.
