Anyone know this error?

[dfearnow1]

Ive been trying for hours to get my post to post 4 decimal plae for a tap cycle. I finally got it to post 4 decimal places, but then I get this error. It was a lot harder than I thought it would be, for something so simple. I can upload other pics of what I changed on my post. But it also errors out when there is not a tap cycle in the program.

You have a problem with something on line number 1483. If you open your post in the Code Expert text editor, your can press CTRL + G to jump to a line number.

 

"label has not been defined" means you have used a variable name that has not been initialized. When you create a "new variable", you have to put an entry a the top of the post like this:

 

tap_feed : 0

 

That "initializes" the variable, and assigns it a starting value.

 

This could be because you tried to use a new variable, or you've just got a name with a spelling error. That will trigger an error message, since that variable name is not defined.

 

Fix that naming error first, and then run the post again. If there is another error, then it would be more obvious, once that name is fixed.

 

After you create a variable, you need to assign it a Format Assignment line. This tells the post processor how you want the numeric portion of the variable to be formatted (4 decimal places for example), and also allows you to assign an optional Prefix string, and Suffix string. In your case, for a feedrate value, you want the string "F" assigned to the variable output.

 

fmt   "F"   12  tap_feed

 

 

Then, in your tapping post block, you could do something like this:

    

ptap$            #Canned Tap Cycle
      pdrlcommonb
      #result = newfs(17, feed)  # Set for tapping Feedrate format
      tap_feed = fr$ #Get feedrate value from operation
     

Note that there is some default logic inside the 'ptap$' post block that will change the feed format for you. Look at the 'result = newfs(17, feed)' line. (I commented it out in the sample above). That line assigns a new format assignment value for that variable. All you normally have to do is change that number. (number 12 gives you a 4 place decimal).

 

So you might consider going back to where you started, and just playing around with changing that number to get the feedrate you want output on the line.

 

Also, be aware that there are two different tapping cycles setup in the stock Mastercam posts. There is "Tap", and then there is "Rigid Tap", in the cycle drop-down menu.

 

UPDATE: Ok, I just looked over the logic in the tapping post blocks, and realized there is a bug in the 'ptap$' post block. The "newfs" line assigns a new format to the 'feed' variable, but if you look at the output of that post block, it is the 'pitch$' variable that controls the output of the "F" value!!!!

 

So change the 'result = newfs(17, feed)' line to 'result = newfs(12, pitch)'...

 

That will fix your feedrate output for tapping...

Colin,

thank s for the reply. But Im completely lost on this side. Here is a pic of what I pretty much copy and pasted from another post from here.

[Colin Gilchrist]

From what you copied, I'm guessing 'strf' is not defined. Go to the "#String and string selector definitions for NC output" section of your post. It should look something like this:

# --------------------------------------------------------------------------
#String and string selector definitions for NC output
# --------------------------------------------------------------------------
#Address string definitions
strm         : "M"
strn         : "N"
stro         : "O"
strp         : "P"
srad         : "R"
srminus      : "R-"
sblank       : ""

Then add a new entry like this:

# --------------------------------------------------------------------------
#String and string selector definitions for NC output
# --------------------------------------------------------------------------
#Address string definitions
strm         : "M"
strn         : "N"
stro         : "O"
strp         : "P"
srad         : "R"
srminus      : "R-"
sblank       : ""
strf         : "F"

You are the man! Thank you so much. It has been bothering me for years.
