Haas Service & tool probing question
Got a question, we bought a used Haas VF3 with probing. I had haas come out and check the machine. they said it needed the new update for the controller. I said ok do it, well now everytime i switch programs i get an alarm with program integ. the haas service man said ahhh no big deal just hit the reset button, i kinda looked at him and thought you kidding me? so then when i was also having there applications guy here teaching us on the probing system, everything seemed ok. but when i run a program and want to check within the program the tool length and diameter after each use to update with any wear, the tool probe will just keep coming down and bump the tool probe and give me the tool probe open error. it does come down normal when i do the first setup to do the legth and diameter to set the tool first time.
And i know everyone is going to say call haas back well i did and still after 2 weeks after the last call still nothing. I was hesitant on buying haas agian and this really sinks it for me that there service is just not there anymore. I have talked to our rep and still nothing, i have stopped calling them cause i see no reason because nothing happens. But yet i have a friggin bill for when that they want me to pay when they came out for this job, i keep telling them that the machine is not running correct since they did the update and i want it fixed before i pay.
well that put a burr up the service guys a$$ and he calls me to ask me what the heck and next time to make sure that he knows about this before it goes to billing, i told him that i called him and also called the rep about the problem but i guess he forgot, he must have gottin in trouble and didnt like it, well i am sorry my machine is running but is a hassle that i have to hit the reset button all the time.
i understand that i might be programming the probe wrong but when i ask the apps guy he says it should work, well come out and show me and i will pay extra if it is my fault, but if it is on the machine side then i am not going to pay for the mess up.
anyone have similar problems with the probing?

Two seperate issues here; Program integrity after software upgrade and probe open for tool setter.
First: I am going to say it; keep calling the HFO until they fix your machine! Don't stop calling. Call Haas Oxnard if you have to.
Second: Probe open alarm needs more explanation regarding what type of system you are using, how old, how you are using it, and possibly some program samples.
(Assuming you have a Renishaw system)
Have you gone through the Renishaw manual thoroughly and tried their sample programs? If you don't have it, you can download from their website.

Hi Haastec,
thanks for the reply. I will call again today and tri to light a fire under them and tell them that i will contact oxnard if it is not resolved by next week.
here is a sample of my program, when i put the tools in i do the auto length rotating to get TLO and Diameter, everything works correct. But when i have this in the middle of my program cause i want to check the TLO and Diameter before it runs each time is where it does not work. What happens in the program it calls for the auto legth rotating before it uses the tool, it starts to come down but ignores the set tool legth and keeps going till it hits the tool probe. and yes it is a renishaw system the haas is a VF3 2003
now when i set it up i give it a rough length, it does the routine and sets it correct in my offsets, but when i put it in my program i am leaving the rough length is that correct?

Let me know if i am the problem?????????????? lol never claimed to be the end all be all in programing lol

I'm assuming you got your macro programming cues from watching the built in programs on the control, because the programming manual has completely different calls. This is how I would check length and diameter on a 1/2" endmill, T1:
G65 P9853 B3 T1 D1 S.5
If you did the same thing, but added Hh.hhh to the above block, the control assumes a tool breakage detection cycle and with the huge value you have in the tolerance, I think it's messing you up. If you simply want to measure the tool and not go into tool breakage stuff, use what I wrote above.

Yes, you are the problem.
Look through the manual as I previously mentioned and try samples like Matt posted.
The cycles that you are using can be made to work, but I forget what all needs to be changed inside the macro programs off the top of my head.
Using the cycles listed in the manual (and like Matt provided) will give the same results, and by understanding how these work will open up unknown amounts of potential for using your probe and tool setter in future programs.
It's time to read up.
