GPP - Coolant

[mattpatt]

Very easy one here for some......

I must be missing the obvious somewhere, but I can't get the coolant option to work properly in my generated program.

I've put:

@start_of_job
if flood_coolant eq TRUE
{nb, 'M8'}
endif

works nicely, but can't get the following to work:

@end_of_job
if flood_coolant eq FALSE
{nb, 'M9'}
endif

tried a few things but not really getting anywhere

Hi Matt, Happy New Year.

I haven't set up my posts to handle the new coolant options myself but have you checked the trace to see if @end_of_job refreshes the variable flood_coolant? If it doesn't, the variable will still be in the TRUE state and your statement won't work.

My posts are set up to turn coolant on automatically and only turn the coolant off for jobs that have a job option "coolant" set to 0, but we work exclusively in Al Al and running without coolant is very rare.

Hi Bob,

And a Happy New Year to you too!

In the "@start_of_job" we have "flood_coolant: on". My statement works for this and outputs the M8 command.

In the "@end_of_job" we have "flood_coolant: off". So I think my statement should work, but it doesn't.

If I change to:

@end_of_job
if change(flood_coolant)
{nb, 'M9'}
endif

the M9 now outputs, but if I then go and turn off the coolant in SC I still get the M9 output. The M8 does not output. The trace shows "flood_coolant:no_action" in both @start_of_job and @end_of_job.

Hmmmm.

As it is 99% of my jobs too are aluminium so I already have the M8 and M9 automatically fired for every generated program, so it's not a big thing. Just wanted to use it.

But I do now have another issue (GPP related)....................new thread perhaps.

Hi Bob,

And a Happy New Year to you too!

In the "@start_of_job" we have "flood_coolantn". My statement works for this and outputs the M8 command.

In the "@end_of_job" we have :flood_coolantff". So I think my statement should work, but it doesn't.

If I change to:

@end_of_job
if change(flood_coolant)
{nb, 'M9'}
endif

the M9 now outputs, but if I then go and turn off the coolant in SC I still get the M9 output. The M8 does not output. The trace shows "flood_coolant:no_action" in both @start_of_job and @end_of_job.

We put the turn off coolant at end of job always. This is a hard stop feature

Matt, shouldn't your if statement read

if flood_coolant eq "on"
{nl, "M8"}
end if

or if flood_coolant eq "off"
{nl,"M9"}
endif

In your original statement you were testing for a logical condition but the trace shows a string value. But I could be wrong....

Hi Bob,

Already tried that and got an "invalid IF statement" error.

FYI, in my mac file I have:

;Coolant_options
flood_coolant = Y

I'll struggle on for now and see if I have any bright ideas. As I said, my GPP is cinfigured so that the M8 and M9 fire automatically anyway whether the coolant option is ticked or not, so not really a problem.

Just hate failure!

Mac file additions:

;Coolant Options
Flood_Coolant =Y
Mist_coolant = Y
;HP_Flood_coolant = N
;LP_Flood_coolant = N
;HP_Through_coolant = N
;LP_Through_coolant = N
Air_Blast_coolant = Y
;Minimum_Quantity_L = N

turn on what you need in Mac to activate in interface

Gpp file additions:

@end_program
{nb, 'M9'}
{nb, 'M5'}
{nb, 'M61'}
{nb, 'M84'

@change_tool
local logical save_blknum_gen
if !first_tool
{nb, 'M9'}
{nb, 'M61'}
{nb, 'M84'}
{nb, 'G91 G28 Z0'}
{nb,'M1'}
{nl,''}
{nb,'''G90 G80 G40 '}
home_flag = TRUE
Skipline = FALSE
call @home_number
op_number = op_number + 1
else
home_flag = TRUE
call @home_number
endif

@start_of_job
if Flood_Coolant eq 1 then
{nb, 'M8'}
endif
if Mist_coolant eq 1 then
{nb, 'M51'}
endif
if Air_Blast_coolant eq 1 then
{nb, 'M83'}
endif

this is how ours is set up

How do you turn coolant off when @end_of_job fires? Or do you turn coolant off in @start_of_job should coolant not be needed.

I have added the following to my GPP file to controll the new coolant options.
Under the @init_post section at the begining of the GPP file I added

global logical Flood_coolant_on HP_Through_coolant_on
global numeric s_Flood_coolant s_HP_Through_coolant

At the @start_of_job section of my post I added
call @start_coolant

At the @end_of_job section of my post I added
call @stop_coolant

I then added two new sections to my post as follows:

@start_coolant ; Added coolant start options

if Flood_coolant eq 1 then
{nb,'M08'}
Flood_coolant_on = true
endif

if HP_Through_coolant eq 1 then
{nb,'M07'}
HP_Through_coolant_on = true
endif

s_Flood_coolant = Flood_coolant
s_HP_Through_coolant = HP_Through_coolant

endp

;-------------------

@stop_coolant ; Added coolant stop options

if Flood_coolant_on eq true and s_Flood_coolant eq 1 then
{nl,'M09'}
endif
if HP_Through_coolant eq true and s_HP_Through_coolant eq 1 then
{nl,'M09'}
endif

s_Flood_coolant = Flood_coolant
s_HP_Through_coolant = HP_Through_coolant

endp

Hope this helps as it works sweet. Dont forget to add the options to the mac file!

Jake,

Thanks, that works.
