It's in hours:minutes


So someone left the printer on for about 15 days.  It has printed for only a total of a bit under 9 hours and has printed a total of 3 meters.  This machine is basically new.  Typically you have to change the teflon part after 500 hours of printing.


I recently serviced a machine for my local library and they had printed 5000 meters.  That's 5 kilometers of filament!

It's unlikely.  If you do a firmware update it doesn't reset those counters.  If you do a "FACTORY RESET" operation it also does not reset those counters.


That's true, but it's of course possible that only the mainboard was replaced... 😈

The numbers are very low, how old is the printer? In short: I would not make a decision only based on those numbers. It's a good indicator if the overall condition of the device matches, but not more.


In this case it doesn't matter much, but for reference:

Be aware that "printing" and "material" counters are only ticking for prints from the sd card. During USB printing only the "machine on" timer is updated every hour.

(assuming that the default firmware is used)

I have no specific reason to suspect anything was tampered with, I just wondered about the numbers, and that it seemed to be a big difference. And then there could be a good explanation, if the printer has been used with USB interface, I understand it may have been running for close to 400h rather than 9h.

I guess the amount of original filament remaining, will give me a hint on this 😉

    Like tinkergnome said: also inspect the rods, bearings, rubber bands, nozzle, bowden tube, and rotating knob for wear, and the housing for scratches. My UM2s have 1000...1500 hours, and they still print fine. But you can see some wear on these parts. Depending on the material and temp printed, expect that the teflon coupler might also be worn (but this is hard to see, you would need to do a cold pull and inspect the outcome for deformations).

    Thanks, I'll keep that in mind!

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!
          • Thanks

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
