Rotate - Force G-Code Angle Output for Platter

[Reko]

Working with a Haas 5-Axis trunnion... 

I have an over-travel in the Y- axis... so I want to rotate the platter ( B-Axis ) 30 degrees so I can reach the pad beyond my "Y" travel.

I've never needed to force a particular angle for the "B" axis platter only before so this is a new problem for me... but when I create a new plane for a 30 degree rotation... the post still outputs A0 B0 no matter what. The Misc-Integers can flip a toolpath 180 degrees from front to back... but it doesn't affect an angle change like this.

Has anyone ever attempted this, or had the same problem?

Thanks in advance!

This is a 100% guess but if you set rotary axis page to rotary axis positioning will it spit the right code out?

You can Try to substitute y axis if you have enough x travel

Thanks for the suggestions Leon82.

I played with those a bit... it doesn't look like it affects the "B" axis output at all.

Not going to happen without a custom Post. The logic in the Generic Fanuc 5X Mill Post only looks at the "Z Vector" of the Tool Plane to calculate the Rotary Address. Since your Vector is "Vertical", the Post cuts at "Top".

Okay, that's what I'm getting.

Thanks Colin.

Solution for anyone else looking at this thread... I gave this plane its own offset number and made the rotation at the machine.

Yeah without writing a custom post I am afraid this will be the way to go about it.
