changing trunion rotation

[loraxian]

Honest. I looked but couldn't find a previous post.

I'm using X7 multi axis. I'm trying to use 2D facing operations on 5 sides of a cube. I want the trunion(on our HaasVF2TR) to rotate facing aft for 4 out of the five faces and then rotate the table in order to machine the four sides. I've messed with the misc values to death but I can't get the machine simulation to change trunion directions. Anybody?

What do you have for your plane settings?

 

What do you have for your axis control settings?

 

Can you put a file up for downloading?

Honestly I find that the machine simulations don't take those into account. You would need to look through your Gcode to see if the code is actually calling out for it because you might never see it in the simulation.

Double check the direction bias settings in Misc Integers #4 and #5.

I think what he is asking is to just reverse the sign of the Secondary Axis (A?) on his machine. Is that correct?

 

When using the Generic Fanuc 5X Mill Post (the VF_TR post is based on this post), you can use Misc. Integer #10 to temporarily restrict the Secondary axis to either Positive or Negative. This switch just temporarily restricts the travel limits of the Secondary, which allows you to force either Positive or Negative output.

 

So try either '1' or '2', and check the output.

 

If you just want to reverse the sign of the Secondary, you need to make a post change.

#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  

The above variables control the setup of the Secondary Axis. To reverse the sign, just change the value of 'rotdir2$'. So instead of 'vecy', change the value to '-vecy'. Or if the setting already has a unary minus (-), just remove the minus sign...

POST SETTING IN MACHINE SIM PROVIDE SECOND ROTAION ANGLE

THIS IS WHAT I HAVE BEEN PLAYING WITH ,MY FIRST TRY ,I CHANGED THE SIM POST SETTING TO PROVIDE SECOND ROTATION ANGLE
