Coolant cancel/call when not necessary

[Newbeeee™]

Hi All,

When posting operations with the same tool [without toolchanging], our post outputs the below example.

 

N0101 T1 M6

G54 G0 G40 G49 G80 G90 X-60.108 Y46.124 S1000 M3

Is there a *simple* way of removing the not needed M8/M9's [either side of the comments]?

Our post is an orginal V8.1 fanuc mill, but has been updated and heavily modified.

I recently downloaded mpmaster from here and noticed it doesn't do this.

 

Any pointers/help much appreciated.

Thanks

Make sure your coolant is on for all ops.

 

Looking at your file it looks like you might have something in your post that automatically turns the coolant off after each toolpath.

Hi newbeeee,

 

Mpmaster has a switch that can do this between cuts.

 

cool_zmove : yes$ #Coolant off with last move

 

Check your post for coolant$ = zero in ptlchg0$ for example.

[Newbeeee™]

Thanks for the help.

Yes, coolant is on for all ops.

 

OK, Newbeeee post editing questions so please treat me gentle...

I have opened up both posts (mine + mpmaster) and looked at the differences (bucket loads).

I have copied the following into mine:

cool_zmove switch into general output settings (header)

cool_zmove line into pncoutput (#movement)

cool_zmove line into pcanceldc$ (#cancel canned drill)

if coolant$ line into ptlchg0$ (null toolchange)

Doing the above has made no difference to the way my post outputs.

 

However, there is a bucket more additional code (such as ptlchg_com, pretract, pretract0 etc) that the mpmaster has over my post.

So is this a lot more involved than my naive 1st thoughts???

 

Cheers

I would start with the Mpmaster and edit it..I am not the post guru. People here will help you though.

Hi,

 

If this line wasn't already in the post, it won't make a differnce if you paste it in.

If this line was already in the post, you should change yes$ to no$.

 

cool_zmove : yes$ #Coolant off with last move

 

You might want to check pretract for coolant changes.

[Bjorn Petersson AME AB]

If the post is as old as v8, and you can't get it working, I'd probably do as Dan suggested. Start fresh with a new Mpmaster.

[Newbeeee™]

Thanks again for the replies.

It works ok for all other ops (facing/pocket/contour etc), it's just drilling it does this.

It's no big deal as the code is 'safe' (and easily edited), but it would be nice if it was *right*.

Thanks again,

Terry

check the canned text button in the ops and your defaults file;looks like it got switched on

[Newbeeee™]

Mike,

Canned text isn't active, in either the ops or defaults?

 

I'll go through both posts again specifically looking at the pretract/end of drill cycle coolant settings.

Cheers
