Problem Probe alarm when not in use?? Any Ideas Guys?

Forums: 

I am using a haas cnc mill. For some reason when I use my macro program to touch a tool off, the machines moves to the tool setter position and the "z" move up and down maybe .05" a few time and throws an alarm stating "Probe Open"... It is acting as if I have my probe in the spindle and is trying to set my works "z" offset. Which it should not be doing due to the fact that I am not running that Macro Program. Normally When I touch my tools off, it will feed the whole way down to the setter and set my tool. And just to clarify I have been running cnc machines for over 8 years and yes I am using the correct program
I wanted to see if taking the probe out of the machines carousel would solve the problem (To make sure it was not sending any signals to the receiver) but the same thing happened. The Probe does not have a micro switch to turn it on either when inserted into the spindle. It is activated by a signal from the receiver when the probing macro is ran. I even reset the machine multiple times.
Is there any parameter or setting that I can turn the probe and receiver off until I need it?
Does anyone have any suggestions?

I switched to the probe and removed it and tried again, but the same thing happened. The Probe does not have a micro switch. I even reset the machine multiple time.

I have no idea what that means. What did you remove? Micro switch?
Aside from all that you most likely have a dead battery.

I removed the probe from the machine. I know some probes have a micro switch on the tool shank. When you put the probe into the spindle it triggers the probes receiver to operate with it. The battery is good I can probe my work piece fine. The problem lies in touching off my tools on the tool setter. The machine thinks the probe is running when its not even being used. Making it so I can not set any tool lengths automatically by macro program.
P.s. My last resort I can manually touch my tools off of my work surface and just not use the probe for my work "Z" offset, But I do not wish to go that route since the setup macros save me time. I rather not manually set everything up.

So your tool setter is cable?
Mine is battery, and it will( if memory serves me) do the "probe open" thing if the batteries die.
If it is cable, is it blinking in a certain manner before it alarms out? The manual has a list of possible problems given the blinks. I'm not familiar with the cable style, so I am going off the remote style here...

The probe is most likely turned on via an optical start. On the Haas Renishaw setup this is what starts the probe then it times out to turn off. Whats the probe model and what macros are you using?

Mine is powered by a battery not a cable. Like I said the battery is fine.
I can use the probe with no problems. There is nothing wrong with the probe itself... It throws an alarm when I want to set my tool length on the tool setter. Not having anything to do with the probe. It just throws a "probe open" alarm.

Yes exactly. For some reason it is not timing out. Let me take a look and I will get that information up for you. It just started happening today.

It throws a probe open alarm because both the "probe" and the tool setter are on the same skip input. What is the model of both the probe and the tool setter? Is the tool setter wired or battery powered as well?

Ok - so maybe I am missing something.
You say the probe works fine?
You do realize that you are describing 2(two) probes?
You have a spindle probe and a table probe.
I assume when you say the probe works fine, you are talking about the spindle probe. But then you say that you can't set tools (now you are talking about the table probe). 2 different probes, with 2 different batteries.
Has this machine table probe ever set tools?
If so, I still believe it is the batteries (what else would have changed?)
If it has worked before, then just try taking the batteries out of the spindle probe and putting them in the table probe and try that first. If it works, you found your problem...and those batteries only last around 6 months so it is a good place to start.

That sounds correct and makes sense. They are both Renishaw. The tool setter is wired to the machine.
Do you think it could be an issue with the wiring? Maybe from contamination or wear?

.

I do understand I am talking about two probes.

I'm just trying to make sure I understood.
This is out of the manual...Could be not re-seating???

It could be a bad M-code relay. I think on the wired tool setter it uses M22 to switch on the tool setter and M23 as the spindle probe start. The probes are quite simple as the are both a normally closed switch. When the probe is triggered it breaks the circuit. Pins 1 and 2 on the skip input will be shorted when the probe is activated and when it is triggered they will be open. You can view this on the diagnostics screen under "skip input". You will have to trace the circuit with a continuity tester and find where the issue is. Should be very simple to locate. Also the Renishaw systems have pico fuses in place to prevent the SSRs from getting damaged. The manual will show you there locations. When you locate the device that is open circuit you can check the fuse.

Nice little wild goose chase we got going on here. Cknoble1, in the future, please try to be more descriptive! You are calling both pieces of equipment "probe", and that is horribly confusing.
With that out of the way, if I'm reading all this correctly, your assumption that the Probe Open alarm is coming from the spindle probe is not a good one. I just ran a tool setting cycle, but held the stylus down before hitting cycle start and got the exact same alarm. I would look for chips or other foreign material stuck in the table probe that is binding the stylus up. Does it move freely when you push on it?

In all fairness they are both "probes". However one is a spindle probe and the other is a tool setting probe. The reason you get the same error is because both "probes" are in series. It wont matter which "probe" is causing the problem since the macro only looks at one thing. That is the condition of the skip input. If the circuit is open at any point it will give you this alarm. Its quite simple to simply trace it out with a continuity tester before tearing into anything looking for chips. It can be many things. best is by process of elimination. Once you locate the offender then you can figure out how to proceed.

I never used the word "probe" for both pieces of equipment! I used the term tool setter! and the term "probe" for the spindle probe! I was not calling them both a probe? and I am trying to be as descriptive as possible.

I appreciate all of your help. I tested the circuits and the tool setter is not functioning properly. I am going to do some more testing, but you have brought me close to a solution. I thank you very much!

And I do apologize if my original posts were a bit confusing. I am not savvy with probes in general. I did not realize that when it said "Probe Open" that it meant my "tool setter probe" was malfunctioning. I thought it was my "spindle probe" that was throwing the error for some reason. That is due to my lack of knowledge with any probing equipment. I just want to apologize again. Thanks you all for your help. The problem has been solved.

The problem has been solved.

What was it exactly? Always good to hear the followup. Glad you got it sorted.

Yes, please share!

We did some circuit testing and found that it circuit was left open. We did a full inspection of the wire connecting the Tool Setting Probe and found the casing had worn and one of the wires were damaged. I took the cheaper way out and cut that section of the wire out. Reconnected them with some solder and wrapped the hell out of it. Works for now I guess. No more "probe open" alarms! Thanks everyone!

All's well that ends well.
Glad you got her up and running...but get that cable replaced ASAP. Have you seen the places that coolant can get itself into?
