Getting g74 on boring g85 cycle.

[medaq]

Not sure why I am getting g74 instead of a g85. Hoping it is something simple but I am not sure.

 

Posted cycle

The post debugger show it going here.

pbore1$          #Canned Bore #1 Cycle
      pdrlcommonb
      pcan1, pbld, n$, *sgdrlref, *sgdrill, pdrlxy, pfzout, pcout, pindexdrl,
        prdrlout, [if dwell$, *dwell$], *feed, strcantext, e$
      pcom_movea
 

 

bore #1 shows correct g85

sg85    : "G85"      #bore #1    - no dwell 
sg85d   : "G89"      #bore #1    - with dwell

I am using the step in the post debugger. The G74 is added right at the *sgdrill in the pbore section.

Search for sgdrill in the post. That will take you to the string select table for the drill cycles. G74 is normally for one of the tap cycles, just above the bore cycles. Make sure Bore 1 has the string G85 associated with it.

What post are you using? Something isn't updating right. Can you post the full array of the sgdrill that shows the fstrsel? My first thought is that maybe the count got messed up somewhere.

Totally agree with ahaslam. If the association is correct something has changed in the table structure. Check a new (unedited) copy of whatever version your post is based on.

You nailed it. I added a new g84 call out. Since the brothers use g77. I like to keep the original programming and add a line, then block the original Line with the '#' I forgot to add that in the pst code. Thank you very much. Post works perfect for drilling again.
