Hello Newbe here,

Can someone tell me why my prints always come out short in height but all other dimensions are OK? The machine acts like it has completed the print, quits and goes home.

Also the last print job I made the machine went through its print cycle all the way to the end but the print was incomplete. There were gaps in the print where i can see the infill.

I am using a Two Trees Sapphire-S CoreXY printer and Ultimaker Cura 4.4

Thanks in advance for any guidance offered.

    Hello latrevino,

     

    the first thing for you to find out here would be wether it is actually the printer/settings (I wouldn't have a clue right now if that is the case) or if your input-data (g-code file) is already bad. You can check that by analyzing the machine-pathes in the cura preview-mode (the middle-button at the top between "prepare" and "monitor"). If you notice something is wrong here already, then a bad geometry (.stl) file might be the reason (non-closed or intersecting surfaces and the like)

    Thanks ZapBranniganm... I appreciate your feedback. Yeah... this is going to be a duesy for me to figure out. This is what I got so far... The print I'm attempting is a fan shroud I downloaded from Thingiverse so I'm assuming the code is not corrupted. I'll download another item to see what happens. Also, following your suggestion it appears that my print starting point is at layer 133 and ends at layer 234. The total print should have 265 layers. Go figure! : (

    Hey latrevino, do you mean by "code" that you downloaded a (ready-made) gcode-file? In that case - did you make sure it is compatible with your machine (at best exacly made for your printer-model)? Or are we talking about an geometry-file (most common is .stl) that you sliced with cura to produce a gcode-file yourself?

    ZapBrannigan, yes to both questions. I downloaded the code from Thingiverse for my specific printer although I have a Sapphire-S printer and it did not specify model... "S" or "Pro". I have also loaded .stl files to Cura for slicing. I believe I am going to zero everything out and start from scratch because I don't believe I had this issues when I first got started but since all this is new to me I can't be sure.

    Mmm, sounds reasonable so far. If you made a lot of changes in your cura settings/profiles then it might indeed make sense to reset and start from scratch. Maybe you should also look for a forum with users of your specific machine. Good luck for sorting things out!

    I am wondering this... since there were no readily available profiles for my printer (Two Trees Sapphire-S) in Cura, and I manually added the printer perhaps that is where my problem is. What do you think?

    Yes, if you accidentally got some settings in your printer-profile wrong this would almost certainly lead to problems while printing. Think of entering a wrong size of the print-space. Although such an error is hard to oversee because you're always working "inside" the machine-space in cura. So if you had specified a space that would fit into a nutshell you'll notice that when you try to slice your first model. But there are other settings that can be done wrong - some printers even need special gcode-sequences for some functions. That's why you best find somebody with the same printer (sometimes there are groups even on facebook) who already defined a profile for cura. Checking the profile is a good starting point anyways.

      • 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.
