If - or statement?

[DavidSV]

So I am looking to have an option set with a MI to have a slow tool change. I would like to have a flag to have it then do a slow tool change to remove the tool also, so for my tool changes, I am looking to have a flag and on my tool change have a logic that goes something like this:

 

If MIxx = 1 and/or Flag = 1 M306

else M6

If MIxx = 1, Flag =1

else flag = 0

 

How can I format that?

 

Thanks

[K2csq7]

Not understanding the need for the flag.....

 

Can't you just say,

 

if mi6 = 1, M306

else, M6

 

what would your flag do??? what will it be "flagging"??

[DavidSV]

The flag is so that if the tool goes in with a slow tool change that it will then be triggered to be removed with a slow tool change.

[K2csq7]

Ok, here is what I came up with....using mpfan...

 

First define your "flag" variable. (I used dsv)

 

# --------------------------------------------------------------------------
# Toolchange / NC output Variable Formats
# --------------------------------------------------------------------------
fmt "T" 4 t$ #Tool number
fmt "T" 4 first_tool$ #First tool used
fmt "T" 4 next_tool$ #Next tool used
fmt "D" 4 tloffno$ #Diameter offset number
fmt "H" 4 tlngno$ #Length offset number
fmt "G" 4 g_wcs #WCS G address
fmt "P" 4 p_wcs #WCS P address
fmt "S" 4 speed #Spindle Speed
fmt "M" 4 gear #Gear range
fmt 4 dsv #hold last value of mi4

Then start with the psof postblock.... you can see what I added between the ####################

mi4 was set to 1 in the second operation.....

 

I didn't do anything with the null toolchange postblock, let me know if you have trouble with that.

HTH!

[K2csq7]

indentation isn't posting properly.....^^^^

[Guest CNC Apps Guy 1]

Yeah, there's no indentation above so just know you can't copy and paste all the above code. Darn BB formatting

[DavidSV]

Ok, so the " | " in

if mi4$ = 1 | dsv = 1,

 

is the or if an if/or block?

[Guest CNC Apps Guy 1]

Yes "|" is or IIRC.

[K2csq7]

Yup,

| = or

& = and

 

 

is the or if an if/or block?

^^^ zooom.... like an F-16 right over my head... LOL

[DavidSV]

So I didn't have time to get to editing my post until this morning. Thanks guys! Heres what I did and the logics I used, in case anyone needs to do something like it in the future and finds this thread.

 

in the post variables i created a variable,

slowtc : 0

 

In the Tool change I replaced the M6 line with the logic

If mi6 = 99 | slowtc = 1

M306

else

M6

if mi6 = 99,

slowtc = 1

else

slowtc = 0

 

Then, in my end of file, I added a line before my M30

if slowtc = 1, M306

 

That makes sure my heavy or sensitive tool comes back out slow and doesn't get slammed around by the high speed tool change at the start of the next program.

[DavidSV]

yes
