[Ro...] Posted February 24, 2023 Share Posted February 24, 2023 So i just spent 2 hours trying to get my machine to home without overtraveling in Y. The power did go down (Michigan ice storm issues), but now while the machine was running. I rebooted the computer 10 times, restarted the cmm 20 times, cleaned the glass scales a couple times, slowed the machine down to a crawl, nothing helped. I even changed the value of the home position several times, nothing helped. Finally when i was about to give up, it just worked. Of course now i'm afraid of shutting the machine down for fear that it'll take several hours to get it back up and running again, what gives?

[Mi...] Posted February 24, 2023 Share Posted February 24, 2023 The stops likely just need adjusted (by service). You're adjusting the position after homing, the home position is 0,0,0 When we've struggled with this to get by until service comes I make sure to move the head in a position so that it hits the problematic stop last and does not drive along it. So in your case I would move it fairly close, but not too close to the X and Y limits so it hits Y last.... if you have to do it again. Link to comment Share on other sites More sharing options...
[Ch...] Posted February 24, 2023 Share Posted February 24, 2023 Cleaned the scales?? NVM, I actually read your post and see that you already said that. Yeah, sounds like a limit switch is going out. Link to comment Share on other sites More sharing options...

[Me...] Posted February 24, 2023 Share Posted February 24, 2023 Blackouts (even brownouts) are a CMM's worst nightmare. I would suggest a dedicated Battery-backup UPS so that the machine at least stops cnc before shutdown. I think it's a good idea to still cycle through the power a couple times just to be sure it wasn't a hiccup. Mainly concerned about the firmware and if something happened to it. In case something was to happen that requires a shutdown (like a bug or similiar) I'd rather be the one to face it than one of the other less knowledgeable shifts. Just my suggestion. 🙂 Link to comment Share on other sites More sharing options...

The last two companies I worked for had the cmm plugged directly into the wall with no surge suppression. The former was in an old building with high power fluctuations. A few blown pcb's later, and we had ourselves a top-of-the-line power conditioning ups. Tip: Get a line interactive ups. When the power goes out, your computer won't even flicker, and your juice will probably last longer than the compressed air supply. Even a $1,000 high-end power supply costs less than a service call, which doesn't even factor in the machine-down cost. . . https://www.amazon.com/dp/B009TZTGWK/re ... s9dHJ1ZQ== .

[Je...] Posted February 24, 2023 Share Posted February 24, 2023 Dirty power (brown out, black out, surges, flickers) are the worst causes for seemingly random CMM and PC failure. All too often a CMM Configuration is corrupted by a power surge. As advised previously, I strongly suggest everyone get a quality UPS system for their CMM and their workstation. An ounce of prevention... Link to comment Share on other sites More sharing options...
[Ka...] Posted February 27, 2023 Share Posted February 27, 2023 Hi, Line interactive USV is different to an online USV. Line interactive means that the device is supplied by the filtered mains directly. Only in case of a mains failure the device is switched to battery ( DC/AC converter ). So brown out, flickers and transient issues are NOT saved by this type of USV. Better to use a real online-USV. This means that the device is supplied by the DC/AC converter only. The mains feeds the battery. So there is not switch between mains and battery operation. The mains for the device is generated by the DC/AC converter which means it´s absolute independend from dirty AC mains. Best option will be a signal by the USV to the CMM control in case of a blackout. All modern USV has integrated such an interface. The CMM can then be brought into a secured state and switched off. regards Karsten Link to comment Share on other sites More sharing options...
