Haas 5 ax error

[savagkd]

Hi all.

 

I'm getting an "ERROR-THE TOO; CAN NOT BE POSITIONED WITHIN MACHINE ROTARY LIMITS" error.

 

After I OK the error, it posts the folllowing.

A90.

 

I'm getting the A120. in the second op. If I post them separately, both ops post A ~90.

 

A 120. is the limit.

 

I know it's something simple. I just can't see the forest for the trees.

 

Please help

 

Thanks,

a120 is your limit but do you have any comp in your g54? that would put you over the limit.

Thanks for the reply.

 

The problem I'm seeing is the A axis should be ~90. for both cuts. I can't figure where the A120. is coming from. It should be a simple tilt A to 90. make the cut, retract, rotate B to 180 and cut the other end.

Do you have your Working coordinate system set to top? Then Tool plane & Comp/construction plane set to your intended rotations?

[savagkd]

Top for all, both ops are curve 5 axis, with lines for tool axis and collision control.

Sounds like the A axis isn't resetting in the post, did you try using force tool change? Are you using two seperate toolpaths? Using force tool change in the tool parameters page will get most posts to reset the A & B axis.

 

Another thing you can try is forcing a pos or neg solution in the misc values. Depending on the post you should be able to do this for the primary and the secondary axis.

[savagkd]

Is there another way to force the A axis positive? I think I'm rotating fron A pos to A neg. I want to rotate to B 180 to machine the other end.

try misc 10 on the Misc page
