Cura program leveling issue?


Recommended Posts

Posted · Cura program leveling issue?

I recently bought a new 3D printer(A CR-10). The supplies included a microSD that was already loaded with the slicer program I needed to slice STL files. However Ultimaker Cura has alot more options and tools available to use, so I much rather use that.

However, when I slice my programs on Cura and begin to print, the nozzle sticks too close to the bed and ruins the print within a matter of seconds. Thing is, I don't know entirely if its a leveling issue or a software issue. Importing the same STL file onto my Creality Slicer and printing it comes out just fine. I don't understand why Ultimaker Cura tries to print so close to the bed while my other slicer doesn't force itself down all the way. Is there a setting that's messing with it? Is there any way I can tell the program to offset by a few mm(s)?

    The Creality slicer itself is an early version of Cura with some cosmetic changes to make it look different.

    The Creality definition files within this version (the official Ultimaker version up to 4.13.1) are essentially all the same except for the build plate size.  All those definition files were submitted to Ultimaker for inclusion into Cura by either Creality or by the author of the files (who is noted as "Trouch.com").   

    Neither the Creality version nor the Ultimaker version ever tell a printer to go below "Initial Layer Height".  If the bed is properly leveled and is at Z=0 then the nozzle should never hit it.  (That should be true for any slicer.)

    But if you have an ABL then things may be different.  The ABL command in the StartUp Gcode that calls the firmware routine to check the bed may need some parameters adjusted (like the Z-Offset).


    If you slice a calibration cube with both slicers and then post both of the gcode files here then a comparison may give a clue as to what is going on.  Also let us know what ABL setup (BLTouch, CRTouch, whatever) might be on the printer.


    My printer is an Ender 3Pro that I manually level with my trusty piece of parchment paper.  I've never had a problem with it hitting the bed and I've never seen a Cura gcode file (either Creality or Ultimaker) with negative Z values.

      • 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.
