Moving A-axis position with initial X,Y moves.

[Mic6]

Hey Guys, my current Post positions the A-axis when I'm down on the part.  Where in the post do I move my A positioning move?    I'm using a Generic Haas Post.  I don't want to switch posts because of all the work I've done to this one.  TIA

Are you sure you are using the generic Haas 4th axis post? are you using axis sub to do the drilling like this.

Yessir

 

 

 

 

No Axis sub, just X-form Toolpath>Rotate by Toolpane.  It's rotary work, but more like flat ro-tab work.  I'm basically drilling holes in a wheel, with the machine making 1 Y move to position on the bolt circle, then drilling and boring, and moving to the next hole via A-axis rotation.  We're trying to see if we can hold a tight TP this way instead of having the table move to each position.  

 

   Is my post set-up why the A move is in with the drilling move?

[Mic6]

Any suggestions on how I can fix the A position in my program?

That's strange,   Can you maybe post a file?  I bet there's something simple your doing wrong.

 

I won't be able to open it till tomorrow morning tho..

[Rstewart]

double post

Will the machine not hold the true position? If you are fighting TP because the machine just won't hold it you'll be fighting it as long as it is running that part with the scrap piling up.

 

Play the tolerance game, run on the LMC side to get the most out of that TP call out. Unless it's regardless of feature size.

Your post is kinda old...I see the executable listed as MP 11.0 which is/was an X2 post. Maybe try one of the latest ones and see if it puts out your A axis. Just looking at the revision list for that post there have been MANY changes.

^ Maybe a MPmaster ^ ^^

The place you would normally move the Rotary output inside the post is the 'psof$' post block. If this is MPMaster you are using, then you might just need to "force" rotary output when working in the "Top" Plane.

 

 

Try finding this line in 'pwrtt$' and uncommenting the line...

           #sav_rot_on_x = rot_on_x    #Uncomment this line to output rotary axis value even when it's not used

Hey Guys, thanks for all the replies.  I've been hesitant to switch posts because of all the mods I've made over the years to my Generic Haas.  I switched to MP Master, and am slowly trying to add-in all the features I had with my old post.  BTW, A-axis output works now     I'll start a new thread on some help I need with this post.

You Lockheed guys and holding onto old post.

You Lockheed guys and holding onto old post.

 

HA!  Well if it works....until it doesn't work.  

 

Geez, the main shop is still holding onto a few Fadals that should have been cut up 15 years ago.
