HOW TO MOVE A MISC INTEGER COMMENT IN POSTED CODE

[jdkhunter1]

      pcan
      #pbld,  *sgcode, *sgabsinc, sg80, e$ #ADDED
      pbld,  sg43, *tlngno$, pfxout, pfyout, pfzout,  [if nextdc$ <> 7, *speed, *spindle], e$ # G43 with spindle start
      if mi4$,
       [
       no_spc$, "G91 Z#612 (BLADE THICKNESS ADJUST)", no_spc$, e$
       pbld, "G90", e$
       ]

GETS ME THIS:

G0 G90 X.1035 Y4.8144
G43 H99 Z.15 S9000 M3
G91 Z#612 (BLADE THICKNESS ADJUST)
G90
Z.057
G1 Z.047 F50.
G41 D99 X.0156 Y4.8621 F27.

THIS IS WHAT I NEED:

G0 G90 X.1035 Y4.8144
G43 H99 Z.15 S9000 M3
Z.057
G1 Z.047 F50.
G91 Z#612 (BLADE THICKNESS ADJUST)
G90
G41 D99 X.0156 Y4.8621 F27.

Do you want the two lines of code inserted every time there is a z move? If so, I think you would need to copy your mi4 if statement to right before the G41 cutter comp line.

In the MPFAN post the G41 cutter comp line is in the following postblocks:

prapidout 

plinout

pcirout

I believe you'll get what you're looking for if you paste the mi4 if statement right before the cutter comp line.

The issue is the 'misc values' get reset when you aren't processing a 'Tool Change'.

You can setup a 'flag variable' to track the status of 'mi4$', and delay the output until processing in 'plinout'.

G0 G90 X.1035 Y4.8144             < OUTPUT FROM TOOL CHANGE (Either 'psof$' or 'ptlchg$)
G43 H99 Z.15 S9000 M3            < OUTPUT FROM TOOL CHANGE (Either 'psof$' or 'ptlchg$)
Z.057                                             < OUTPUT FROM 'prapidout' (G-code 0)
G1 Z.047 F50.                               < OUTPUT FROM 'plinout'      (G-code 1)
G41 D99 X.0156 Y4.8621 F27.   < OUTPUT FROM 'plinout'      (G-code 1)

Start by initializing a variable, near the top of your Post:

mi4_flag           : 0

Then, capture if the value is '1' during Tool Change (need to put this in 'psof$' and in 'ptlchg$'):

      pcan
      #pbld,  *sgcode, *sgabsinc, sg80, e$ #ADDED
      pbld,  sg43, *tlngno$, pfxout, pfyout, pfzout,  [if nextdc$ <> 7, *speed, *spindle], e$ # G43 with spindle start
      if mi4$, mi4_flag = yes$ #Set flag
      else, mi4_flag = no$   #Reset if necessary

Now, add your logic to 'plinout':

 plinout         #Output to NC of linear movement - feed
      pcan1, pbld, n$, sgfeed, sgplane, `sgcode, sgabsinc, pwcs, pccdia,
        pxout, pyout, pzout, pcout, [if motst$, feed], strcantext, pscool, e$
      #Modify following line to customize output for high-speed toolpath
      #tool inspection/change points
      if rpd_typ$ = 7, pbld, n$, "M00", "(TOOL INSPECTION POINT - POST CUSTOMIZATION REQUIRED)", e$
      if mi4_flag,
        [
        "G91 Z#612 (BLADE THICKNESS ADJUST)", e$
        pbld, "G90", e$
        mi4_flag = no$ #Reset Flag, to prevent output on every "linear move"
        ]

Thanks Colin, it worked perfectly.

I did not know this, thanks for sharing Colin!
