Adding M135 to my post

[lou]

My post does not output the M135 automaticly so I searched for a thread on this and found.

 

Thread

 

Now I get an error "Variable not defined: use_pitch"

 

Can anyone tell me why????

 

Thanks in advance, Lou

[mayday]

put this in the general output settings of your post

should be near the top of the pst file

 

use_pitch : 0 #0 = Use feed for tapping, 1 = Use pitch for tapping

Depends on what post you are using. use_pitch is not in MPFAN or some of the other posts. Assuming it is a preparatory command of some kind, this is what I did with a couple of my posts. You can see my changes where my initials are [cdm].

 

This one needs 'G93' before tapping, I have another that needs 'M29' in the same spot so I used the same idea:

 

ptap #Canned Tap Cycle

pdrlcommonb

result = newfs(12, feed) # Set for tapping Feedrate format [was 17] (cdm)

pbld, n, "G93", e # (cdm)

pcan1, pbld, n, sgdrlref, *sgdrill, pxout, pyout, pfzout, pcout,

prdrlout, *feed, *speed, strcantext, e

I am posting to a Makino S56 w/ a fanuc control and it need the M135 in the post I have been putting it in manualy but once in awhile I forget. and break a tap.

 

So far the line that Mayday told me to add in worked now I am getting another error. Variable not defined: tapflg maybe I dont need it or is there another user def. I have to put in. I beleive I will have the same problem with "pitch="

 

Here is what I have so far..Again THANK YOU for the help!!!!

 

ptap #Canned Tap Cycle

pdrlcommonb

#RH/LH based on spindle direction

if use_pitch, pbld, n, "G95", e

if use_pitch = 0,

[

n, *sm05, e

n, "M29", *speed, e

pcan1, pbld, n, *sgdrlref, *sgdrill, pxout, pyout, pfzout, pcout, *peck1,

prdrlout, dwell, *feed, strcantext, e

]

else,

[

if met_tool, pitch = n_tap_thds # Tap pitch (mm per thread)

else, pitch = 1/n_tap_thds # Tap pitch (inches per thread)

n, *sm05, e # Force Turn Off Spindle

n, "M135", *speed, e # Set Rigid Tapping Active

pcan1, pbld, n, *sgdrlref, *sgdrill, pxout, pyout, pfzout, pcout,

prdrlout, *peck1, *pitch, !feed, strcantext, e

]

pcom_movea

tapflg = 1

[mayday]

Misc variables

 

tapflg : 0 # Flag for tap cycle

 

keep posting as you get the errors

 

well find them all sooner or later

[lou]

Variable not defined: pitch

 

Here is the next one Mayday...Thanks agian!

[mayday]

# Toolchange / NC output Variable Formats

 

 

fmt F 2 pitch #Tap pitch (inches per thread)

[chris m]

#1 Still don't know what post you are using

 

#2 In my opinion, you are making this more complicated than it needs to be; just plug the 'M135' in where your 'M29' is now

[lou]

Ahh, Thank You. ok, I have been known to make things complicated My wife would be the first to tell you that.

 

The last entry of Mayday's fix the errors but did not post out the M135. I just made the change that Chris asked me to try and it worked.

 

Now....... I think I have to change one more thing for this to work. My post is still putting out the P10000 for SGI mode and I dont think I can have that during a tap cycle.

 

This is what I am getting now.....

Thanks again for all the input

[lou]

I keep forgetting to type this in......

 

 

I am using MPFAN-MAKINO-SGI.PST it was supplied to me by the people who sold us the machine. Everything works great but the tapping cycle.

[Psychomill]

A couple ways to fix this. The easiest I think is to add the cancel at the tap cycle:

 

ptap #Canned Tap Cycle

pdrlcommonb

#RH/LH based on spindle direction

if use_pitch, pbld, n, "G95", e

if use_pitch = 0,

[

n, *sm05, e

n, "G8P0", e # Cancel G8/G5

n, "M135", *speed, e

pcan1, pbld, n, *sgdrlref, *sgdrill, pxout, pyout, pfzout, pcout, *peck1,

prdrlout, dwell, *feed, strcantext, e

]

else,

[

if met_tool, pitch = n_tap_thds # Tap pitch (mm per thread)

else, pitch = 1/n_tap_thds # Tap pitch (inches per thread)

n, *sm05, e # Force Turn Off Spindle

n, "G8P0", e # Cancel G8/G5

n, "M135", *speed, e # Set Rigid Tapping Active

pcan1, pbld, n, *sgdrlref, *sgdrill, pxout, pyout, pfzout, pcout,

prdrlout, *peck1, *pitch, !feed, strcantext, e

]

pcom_movea

tapflg = 1

I tried to copy and paste this into the post and got the same thing??? It seems like you should be able to turn that off just for the tap cycle??????

 

anymore Ideas??????

[Psychomill]

When you post the cut, did you get the "G8P0" right before the tapping? The G5 will still post in the 'main' because thats written in the 'psof', 'ptlchg' and 'ptlchg0'. You should be getting the cancel right before the tapping which should allow this to work on the machine.

 

There is a way to not post a G5 for taps but it will require a lot more editing. I just suggested this for a quick fix.

 

[lou]

THANK YOU ALL!!!!! It is now fixed. There were 2 areas that had the same code in it. I was changing the wrong area.

 

Hats off to everyone that helps out on this forum. These are the trying times when I am glad there is someone to lean on to help through the problems.

 

Here is the final code that makes (atleast my machines) work.

 

ptap #Canned Tap Cycle

pdrlcommonb

#RH/LH based on spindle direction

if use_pitch, pbld, n, "G95", e

if use_pitch = 0,

[

n, "G05P0", e # Cancel G8/G5

n, *sm05, e # Force Turn Off Spindle

n, "M135", e # Set Rigid Tapping Active

pcan1, pbld, n, *sgdrlref, *sgdrill, pxout, pyout, pfzout, pcout,

prdrlout, dwell, *feed, strcantext, e

]

else,

[

if met_tool, 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, pxout, pyout, pfzout, pcout,

prdrlout, *pitch, !feed, strcantext, e
