Error in G-Code


Recommended Posts

Posted · Error in G-Code

Hey Guys!


So to make it short: Im fairly new to 3D Printing, since i got my first one for Christmas. I have some problems with walls being rough, but thats another topic. Yesterday i wanted to print my 20th Calibration Cube with new settings, so i sliced it in Cura 4.13 and started printing it. Midprint i heard some loud rattling in the room next door and found my printhead completely burried in a half printed Cube. I stopped the print checked the printer, but couldnt find any damage. So i turned on my Computer again and looked a little bit a the G-Code of the crashed cube. There i found a sudden change from Z13.3 to Z9.175, near the end of a "fill" routine. Now i wanted to know, if this is something, that happens quiet frequently, or if i was just very unlucky? And is there anything i could do to prevent this in the future?


(If i now slice it again with the same settings, there seems to be no problem and it prints completely fine)


Thanks! 🙂

    I don't think it's Cura or nobody would use it.  Did you post the file that was on your hard drive(?) or the one from the memory card?  I would suggest that you format that memory card.  It may have bad sectors and so the gcode gets written incorrectly.  If it came with the printer then copy the stock files to your hard drive before formatting the card.


    It could possibly have been something strange in your settings, but Cura knows better that to drop the Z below a previous print height.


    If you can re-create the settings you used when that happened and then use "File | Save Project" to create a 3mf file with all the information in it, and post that 3mf file here that would be helpful.  Post that Gcode file too (if you still have it).

      • 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!

      • 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.
