Coolant / Air ON OFF help

[mwright780]

Trying to get my machine def to post g83 air on g84 air off, I can change the post and get air on but still get m9 for off and I need g84, using a custom haas post, I have changed the setting in post for the code I want but its not working.

 

PLEASE HELP

 

spending to much time editing programs for air

Do you want to just replace the M8 & M9, or use the air independently and keep the coolant calls as they are?

[mwright780]

I want the option off m8/m9 or m84/m83, we use air about half the time and coolant the other half

scool55    : "M89"                #Coolant 3 off value

Are you using X style? could you just use one of the above and change the Mcode right there in what I posted?

If you're using the old coolant commands this could solve your problem.

 

Define label "used_coolant". use this to save your coolant$ value in ptlch$. Then set up a condition in pretract.

 

 

 

used_coolant : 0
# Coolant M code selection for V9 style coolant
sm09 : "M09"	 #Coolant Off
sm08 : "M08"	 #Coolant Flood
sm08_1 : "G83"	 #Coolant Mist
sm08_2 : "M08"	 #Coolant Tool
scoolant : ""	 #Target for string

ptlch$

....
n$, *sgcode, pfzout, strr0, smaxrate, scoolant, e$
used_coolant = coolant$ #Make sure to put this line after scoolant.

....

pretract
....
if used_coolant = 2, n$, "G84", !scoolant, e$, else, n$, scoolant, e$ #Add this in front of scoolant.
...

Thanks Jack , that worked

I'm trying to use Alex's method above with the old style coolant. The M83 turns on the air properly but I still get M9 instead of M84 to turn it off. Does anyone see why this wouldn't work? Here are some snippets from my post. I'm using the Haas post from the install CD.

i'm not a post guru, but in your string you call smo8_1 for the "M83". and capture this in "used_coolent"

but in the pretract you are looking for "smo8_2" for the "M84" call

 

HTH Ken,

[Thad]

Thanks for the reply, Ken, but I'm not sure what you mean. I don't know what "smo8_1/2" do, I just copied Alex's code. My post editing skills are beginner at the very best.

This is interesting. If I add more tools to the program, different things happen. Notice the different behaviors below.

Thad,

 

Check out a stock MPMaster, look at how they handle the different coolant options for "old style" there lies your answer

[Radical1]

I belive that the answer may be in the machine definition. The general machine parameters allow you to create new coolent commands. If you uncheck the "support coolent using coolent value in post processor" you can then make a new coolent command for the air. I have done this for the bed wash option on HAAS mills before.

[Guest]

With the "old style" coolant, in the post the off command is ONLY defined as M9.

 

You need to set a check when turning it on, so that it understand which coolant on command was used, then you can set which command to use to turn off the one you actually turned on.

I tried that initially (using X style coolant) but didn't like where the coolant was turned on or off. Changing the location of the on/off codes didn't seem as straight forward as the old style coolant with my limited post editing abilities so I opted for the method that I'm now trying to get working. Alex's method seemed like an easy option. I also have an extensive ops library that would need every op changed because the coolant dialog box is different with the X style coolant. That was a major factor in the decision as well.

[Thad]

There's a command to turn off the bed wash?

[Radical1]

Sorry, its for a Hyundai, and the code is M46.

[Thad]

After no success with Alex's method, I'm switching over to X style coolant. As shown below, I've made K2csq7's recommended change, along with unchecking the first box in the machine def. However, my post is still outputting a M9 to turn the air off, rather than a M84.

 

Thoughts?

Thad,

 

Check your Machine Definition. In the Coolant options there is a checkbox for "first off command shuts off all coolant options". You need to disable that checkbox, which tells the post to use separate Off codes for each option.

 

Hope that helps,

 

Colin

[Thad]

Perfect! Thanks Colin.
