Strange Error affecting All CMMs: Critical Error

Catherine Gehman

We have many CMMs in our shop, and almost every one gets this critical error every day (ref image). The content of the critical error all relates to memory issues. We have added the maximum amount of RAM within our PCs, and still see the error. To bypass the error, the computer is restarted, and everything works like normal until it pops up again. It seems to occur at the end of the program while generating a report, but I can't confirm it only happens then. For context, in 2025 we have reported 101 instances of this error. Has anyone gotten this error, or something similar? We do use a software to launch all our programs, and are investigating if this could be the cause, but it seems like a PC-DMIS issue since its occurring around report generation. Here is a snip of the header of this error, anyone have any ideas?

    I could... I dont think I could take the time to reproduce the error through this method since I can't take the CMM out of production for that long, but I could monitor the memory useage when running from the desktop versus when running from the server. Ideally, I would expect this to show a spike in data useage when ran from the server. Maybe the error would occur when that spike is so great, it uses all memory resources for that second. If ran off the dekstop, maybe I wouldn't see such a spike?

    "Generally" speaking it's best to run programs from the local CMM instead of a network drive if possible. This eliminates network lag/errors/corruption and doesn't stop inspection when the server goes down. We use a process where all the master CMM programs are stored on a backed-up network drive that's write protected so only certain people have access to it. The programs are copied and loaded locally on the CMM that needs them. This also saves on calibration time, as we have a process of adding/removing programs when needed and only have to calibrate the probes/tips needed for those jobs.

    And things wont grind to a halt if a firmware update or windows update creates a situation that the Demon finds unpleasing.
