Edit Post to output M29 at Tap operations

[kkominiarek]

I need to output M29 each time I tap with two machines/controls I have.

The spindle speed will change but M29 will be constant.

 

**This is output at present

T3 ( TOOL-3. - 1 1/8 -12 TAP )

( TAP HOLE )

M6

G0 G90 G54 X5.25 Y5. S240 M3

G43 H3 Z4.

G98 G84 Z-2. R.1 F20.

G80

M5

G91 G28 Z0.

 

****This is what I need****

T3 ( TOOL-3. - 1 1/8 -12 TAP )

( TAP HOLE )

M6

G0 G90 G54 X5.25 Y5. S240 M3

G43 H3 Z4.

M29 S240

G98 G84 Z-2. R.1 F20.

G80

M5

G91 G28 Z0.

 

Any help as to where to make the edit will be much appreciated.

Use the debugger to find where the M03 is output from, then put a conditional statement around that to look for the tapping opcode & output the M29

 

i.e. (mpmaster)

 

 

pfspindleout     #Spindle speed and M code output forced    
     if not((opcode$ = 3 | opcode$ = 16) & nextdc$ = 3 & rigid_tap), *speed, *spindle

 

 

Change to

 

 

pfspindleout     #Spindle speed and M code output forced    
     if opcode$ = tapping, 
       [
       if not((opcode$ = 3 | opcode$ = 16) & nextdc$ = 3 & rigid_tap), *speed, "M29"
       ]
    else,
      [
     if not((opcode$ = 3 | opcode$ = 16) & nextdc$ = 3 & rigid_tap), *speed, *spindle
      ]

 

Just a guide, nothing concrete there (don't know the opcode for tapping off the top of my head).... and you may have to make the changes in multiple places depending on if it is the first tool in the program, if your calling the same tool twice....

In the general output settings, I use pitch for tapping not feed. Then:

 

 

The ptap section:

 

ptap$            #Canned Tap Cycle
     pdrlcommonb
     #RH/LH based on spindle direction
     if rigid_tap, pbld, n$, *sm29, *speed, e$           #Rigid Tapping
     if use_pitch = 0,
       [
       pcan1, pbld, n$, *sgdrlref, *sgdrill, pdrlxy, pfzout, pcout, pindexdrl,
         prdrlout, [if peck1$, *peck1$], *feed, strcantext, e$
       ]
     else,
       [
       if metvals, pitch = n_tap_thds$  # Tap pitch (mm  per thread)
       else, pitch = 1/n_tap_thds$       # Tap pitch (inches per thread)
       pcan1, pbld, n$, *sgdrlref, *sgdrill, pdrlxy, pfzout, pcout, pindexdrl,
         prdrlout, [if peck1$, *peck1$], *pitch, !feed, strcantext, e$
       ]
     pcom_movea

 

#Misc Gcode strings

 

sm29       : "M29"          #Rigid Tapping

[neurosis]

Mpmaster has a switch for this.

 

 

rigid_tap   : 1     #0 = Floating tap output, 1 = Rigid tap output (suppress spindle output and output M29)

 

 

n/m, spade beat me to it.

[kkominiarek]

I didn't want to use a misc value.....just to keep it simple.

 

Using post debugger as a guide, I hard put the M29 in the tap cycle and added *speed

as well. Seems to do what I need.

 

Thanks for suggestions.

this is what I have in my MpMaster ptap$ line:

 

if rigid_tap, pbld, n$, *sm29, *speed, e$ #Rigid Tapping

if use_pitch = 0,blah blah blah

 

 

the *sm29 is forcing the M29 code when Rigid Tapping is on (I always use Rigid Tapping)

 

 

edit:

nvm, didn't see Spade's post.

[kkominiarek]

We use rigid tapping as well.

 

My post Tap section had no mention of rigid tap....it is very minimal.
