  • CMM not taking hits

    Following a novice operator, and now the CMM isn't registering hits. Nothing's showing up in the hit buffer, no chime from the computer.

    It was working great last night.

    The probe enable light is lit up on the jogbox.

    Aluminum part held in place on top of 123 block with 2 sided tape, so it's not a magnetism issue.

    Yes. There's only one program open.

    I closed out of the program and reopened it. I restarted PC-Dmis and then rebooted the entire system, nothing's helped.

    Any ideas what setting might have accidently gotten changed?

    Did someone crash it?

      Nothing was said to me, other than: "Slow day. I had a chance to mess with the CMM..."

      When I sat down to the unit, a new blank program was up, but no evidence of a crash.

      I just got an error message: Cannot find CAD nominals within nominals tolerance...

      never seen that message before.

      We don't have access to CAD. Might that be a setting that he changed?

        Maybe the health of your hardware changed. For easy-peasy fix, like you did...reboot everything. Don't know what your probe is, but when you rebooted do you have the red light on?
        Lights on the usual boxes?
        My total CMM experience only consists of the TP-200. Red light/ light/flickering light not good (or a shrill noise = not good) bang-crash-RBE:::::::::
        What is your hardware list?
        'Following a novice operator...' I don't really understand, but if that is a 2nd shift or the like, maybe inquire as if there was a crash. Old age hardware can die in their sleep, but .....

        Barry.... you beat me to the query!
        If you don't suspect hardware, can you restore your Windows to a day or two previous?
        'Slow day......' oh ... now THAT.... along with novice and CMM usually never ends up good for anyone.......

          I'm the 2nd shift guy. As such, I've had more time to sit and figure things out. I'm the go to guy, supposedly...

          I'm on an island here. I have nobody on this shift that I can ask about GD&T, let alone anything about the CMM.

          Regarding the build, the wrist says: HH-A58-H2.5.
          The scan head coupling says: HA-TC-L

          I switched probes during my attempts at finding a solution.

          One of the oldest lessons I've learned when working with machinery that's suddenly not doing what it had been doing is to ask myself "What changed?".

          As I wasn't here when it changed, I can't be certain, but I don't believe whatever changed was altered intentionally or with malicious intent. I suspect a simple keystroke or mouse click in just the wrong place is to blame. Ugh.

            I just did a system restore (to yesterday morning, when the unit worked fine).

            The system came back up and told me that I hadn't lost any files.

            I reloaded PC-Dmis, and proceeded to take a couple hits. . . At least I tried to.

            I got an error message: "Cannot find CAD nominals within nominals tolerance".

            I'm thinking even more that a setting was altered.

              This system was purchased as a year old floor model early 2018. It came with 2017R2, but was upgraded last year to 2018 R2.

              Hardly what I would call "old age hardware". I'd like to figure out the issue before having to report to my superiors that the system isn't working.

              They bring a tech in, and find out it's a setting? Somebody's head is going to roll.

                Success!

                I searched the error message both here and in Index, and it led me to check the Setup Options (F5).

                "Find Nominals" was indeed checked, and would automatically lead to an error message, as we're not using CAD.

                Clicked that off, and we appear to be up and running again!

                I'll leave this thread here as a reference to any who may have this issue in the future.

                  Glad you got your problem solved.
                  *tip* SAVE your Reg Editor data regularly. Good to fall back on the backup when after someone has pushed a checkbox in F5 because they thought:
                  "I wonder what THIS button does?" although definitely better someone does that at a CMM than in a cockpit @ 33,000 ft.

                  Reg editor? Self taught.

                i bet originally you also had two programs open.

                most common rookie (and expert) mistake.

                ALWAYS ensure you don't have multiple programs open if you're not registering hits.

                People have a tendency to do things and then think, "****. i messed that up. open a new program and try again."

                  That's a bet you lost.
