Posted · Cura Changes Z Height from -1.410 mm to around -5mm, completely messing up my print.

Hey guys. So this has been happening on my Prusa Mk3S for a little bit and I'm not sure what's going on at all after looking through the g code and all. I've used 2 different slicers and I prefer Cura, though it has been giving me a bit of a rough time. When I print with Cura, the print begins with the autohoming sequence and auto bed levelling, which goes perfectly. After this, when I check the Z offset in the Live Z Adjust menu, it appears as a number around -5. I'm not sure what the actual number is because I don't want to damage my build plate anymore. This setting stays on the printer until I restart it via the X button or just turn it on and off. After I restart, it goes back to -1.410mm before I start another print. I'll leave my GCODE file here and hopefully you guys can find something I didn't. I use octoprint as well, but I've exported the GCODE directly to the sd card with the octoprint server off so I don't believe it's that. I've also used the same STL with PrusaSlicer and it works perfectly fine. Thanks!

    There are a couple of things about your Startup Guide in regards to Marlin firmware.  These may be because your "Prusaware" is different.

    G28 does not list a "W" flag.

    G80 is not a leveling command.  Typically it would be G29 or M420.

    G1 Y-3 is an odd move.

    The purge line appears to be from X0 Y-3 to X60 Y-3 and then continues to X100 Y-3.  There is no mention of a Z height so it appears to be at a Z of zero or some offset called by M851.

    I think a Prusa forum would be your best bet for support.

        UltiMaker Cura 5.3 stable released

        ArunC posted a topic in Ultimaker Cura,

        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

        Here it is. The new UltiMaker S7

        MariMakes posted a topic in Official news,

        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 🎄

        Cura Alpha With New Tree Support 🎄

        MariMakes posted a topic in Ultimaker Cura,

        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.
