Leaning prints, initial layer shifted

Posted · Leaning prints, initial layer shifted

New to 3D printing, have new printer, leveled bed, running test prints to tune settings for quality...

 

Attached pics tell the story

Already checked all belts/pulleys.

Any suggestions?

 

Thanks!

    Hi there, thanks for getting in touch.

     

    It's really difficult to diagnose remotely. From your bottom image it looks like your print is warping on the plate, so try using adhesion in Cura. A brim will give it some anchorage to the bed and can be removed when finished.

    For the upper photos it looks like one of your axes is slipping.  Do you know which one?  X axis?

     

    This can have MANY causes.  The most common is a loose screw on a pulley - you have to tighten the hell out of those set screws - enough so the tool twists (typically - I don't know your specific printer).

     

    Also if you built this printer yourself or messed with the settings, you may have "jerk" or "acceleration" set too high on the printer for the axis that is slipping.  Typically if the entire bed moves - that axis has to accelerate more slowly.

     

    Also the slipping axis might have much more friction and the steppers just can't accelerate that axis normally.  Or your stepper drivers may be overheating and shutting off (they typically shut off for a portion of a second).

    By the way - a third issue - in the bottom most photo you posted - those 2 vertical lines look vertical so no axis slipping there - but the curve is wrong - concave instead of convex.  That's typicall when the bed is too hot.  As you get farther from the bed you get less heat.  With high heat the liquid PLA is pulling inward like a liquid rubber band as it prints that end of the part.  But as you get to cooler air a few more mm off the bed it recovers.

     

    60C is a good printing temp - if you have an IR temp sensor you can check the bed temp with that.

      • 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.
