Chaanging A & B axis settings in Haas trunion post.

[Orthopedic100]

Im using a Haas T5C2 5 axis roatary indexer and can not for the life of me get it to post the correct angles. I have the tool planes and the Wcs set correctly in MC5. When it post it seems the B is off by 180 degress and the A is off by 90 degrees. I have tried the machine definition file and to no avail has it helped. I'm assuming editing the MD file doesnt help and it has to be changed in the post. Please help!!!!

Attach a file for us to check out (Zip to go), along with the code you SHOULD be getting.

You will get much more help that way.

Attached is the file, the toolpath groups are labled with the correct rotation that I need. The post is all over the place and I

would appreciate any help. Thanks

A rotates about X & B rotates about Y?

Is that how your machine is?

Yes exactly.....

I took a look at the file, I was able to get close with the below settings in the post.

 

 

rotaxis1$ = vecy  #Zero       
rotdir1$  = -vecx #Direction  

#Secondary axis angle description (in machine base terms)
#With nutating (mtype 3-5) the nutating axis and this plane normal
#are aligned to calculate the secondary angle 
rotaxis2$ = vecz  #Zero        
rotdir2$  = -vecy  #Direction

 

 

But all work done on the left & bottom planes is still coming out reversed. If I have a chance tomorrow, I will try to dig into it some more. It is repositioning itself or something (the X values on the left plane are negative when they should be positive).

 

The above settings should work for all planes but the left & bottom.

Yeah I did the same thing with similar results, their has to be something else causing it to go weird for some reason.

Shoot it to your reseller, that's what they are there for.... (& it won't be hacked together LOL)

is this a rotary on rotary set up? if so, your best bet is dave at postability or in-house. one of my customers uses dave's post with zero edits and it worked the very first time i delivered to customer.

HAAS TRT post supplied w/ MC outputs correctly for me....

although i haven't opened this file.

That is what I did, I'll wait and see what happens. Thanks

I think that I know how to set it to work. if you are still interesting inform me. but I will need some more data to ask you before try to correct it to work!
