Lathe Tailstock Crash

[trentSMU72]

At the beginning of my programs for lathe the post is positioning on part and moving in both z and x axis causing a possible crash into the tailstock. How can I change this to move in first z and then x when positioning. This occurs every time it goes to position from the home position. The post I am using is Fanuc turning Version- 44087.

Bellow is example of post with error in red.

Hmm, that's interesting. I can confirm this behavior. I'm checking in with a developer to see if it's known what the thought process is behind that. It does appear to be a simple enough thing to change, but I'm going to wait to hear back before I make my suggestion.

So what you're going to want to do is edit line 1130, which is currently this:

writeBlock(
      conditional(getProperty("type") != "A", gAbsIncModal.format(90)),
      gMotionModal.format(0), xOutput.format(initialPosition.x), yOutput.format(initialPosition.y), zOutput.format(initialPosition.z)
    );

We're going to split it into a Z and then an X move, like this:

 writeBlock(
      conditional(getProperty("type") != "A", gAbsIncModal.format(90)),
      gMotionModal.format(0), zOutput.format(initialPosition.z)
    );
    writeBlock(
      conditional(getProperty("type") != "A", gAbsIncModal.format(90)),
      gMotionModal.format(0), xOutput.format(initialPosition.x), yOutput.format(initialPosition.y)
    );

This will give you code like this:

17 G54

N18 M8

N19 G97 S4000 M3

N20 G0 Z0.      <---- approach in Z first

N21 X3.1496     <----then in X secondly

This fixed it. Thank you sir

Is there a way to implement this (also using Fanuc Turing) but only when the "use tailstock" box is checked?  I want it to rapid shortest route if there is no tailstock in the way.
