Inventor HSM Fanuc post processor v Cincinnati Arrow with CT FNC 4 control
Hi People!
I have an issue when posting files to my Cincinnati FNC control. I use the standard generic post processor that is supplied with my CAD/CAM Inventor HSM 2016.
90% of the time this works fine but when doing more complex shapes using the 3D strategies, it [U]sometimes[/U] throws up an error at the control.
The control tells me "the circle end point is incorrect" or similar, I've been looking at the error all day but can't remember the exact wording, sorry.
I think the error is something to do with the way a Fanuc needs the I J K data presented or used which, I think is different to what the Control Techniques FNC needs. Lots of thinking but no answers.
Do any of you rocket scientist understand this black magic and could help me please? I need to pin point the problem and then (gulp!) get the post changed to suit.

hi, i had have the same problem but my controller is syntech EZ4 up to now i could not sort it out ,have you manged to solve it ?please if you do so let me know the remedy.

Mathematically what you have should work. Are you using tool radius comp? Are you using an origin shift? These things could cause errors with some older Fanuc controllers.

Hi, Thanks for your responses and apologies for my slow reply. I actually solved the problem by trial and error (read = accident) in the user defined parameters in HSM's generic Fanuc post. By switching the "useRadius" to "yes".
I don't use radius comp at the control and never use any origin shifts because I get easily confused.
I'm glad to report by switching the above mentioned parameter I can run all of the strategies available to me without error. If only everything were that simple.
