question about opcode$

[jlw™]

is it possible that any of these options change the value of "opcode$"?

Pretty sure all drill cycles are same opcode, differentiates by drlcyl (sp?)

Just looked it up and it is drillcyc$ that differentiates the different cycles

When you are preparing to output code inside the Drill Cycle, the value of 'drillcyc$' is set. NCI G-code 81 is read at this point, and all the cycle parameters are available.

For 'opcode$', it will always be '3' when drilling.

Since you are looking at 'opcode$', my guess is that you want to "predict" what the next 'drillcyc$' variable value will be, and you probably want to test this at the 'Tool change' event. Am I right so far?

MP has a special mechanism called 'Get Next Op' that needs to be turned on. (This is on by default in almost every Generic Post). When this is enabled, MP will calculate the "next variable values" for you. This is a limited set of variables that allows you to get some of the "next operation's data". One of the things it "grabs" by looking ahead is the "Next Drill Cycle value".

The variable you want to test is 'nextdc$'. That will hold the value in the Drop-Down list for the Next Drill Cycle. Remember that this is a zero-based index. (1st item in the list is Drill Cycle 0, 2nd item is Drill Cycle 1, ect.)

Thanks gentlemen, I actually figured it out with some testing.  I formatted a statement and made it output after every op so that I could see the value.  

Colin, this is in regards to the post I mentioned to you that needs some love.  I'm trying to love on it a little.  I had a problem where Y axis output (only Y, not X) was not being output from drill op to drill op if they had the same Y value.  Not even on different planes.  I have not had parts repeat X values but even on a five sided part.  Imagine a perfect square, with a hole dead in the center of 5 sides.  If I drill the Top, Front, Back, Left and Right faces I only got Y output on the Top.  I was only seeing this with drill ops and only Y axis.  So I added [if opcode$ = 3, pfyout else, pyout] to my prapidout section.
