Does this version support zyyx printer. I downloaded cura 5.2 and was disappointed to see the printer has disappeared from the list. Should I upgrade or downgrade?

    Having real trouble with 5.3.0!  Project files mostly don't open with the choice to update a machine, rather just dumps the models into the existing project therefore none of the settings from the project file are loaded in.  This is totally unusable for existing projects.

    Cura 5.30 always snap the sliced result to build plate. The "Drop Down mode" option is unticked.

     

    Is this a new feature? Because I didn't encounter this before. How to turn it off? All plugins are disabled.

    The setting you need isn't visible when "Generate Support" is enabled.

    Turn off "Generate Support".  Go to the "Mesh Fixes" and un-check "Remove Empty First Layers".  Go back and turn on support.

    image.thumb.png.6f487c6bcde44d466dbd2e0daa368ab4.png

     

    This is from the fdmprinter.def.json file in regards to "Remove Empty First Layers":

    "default_value": true,
    "enabled": "not (support_enable or support_meshes_present)",

     

    I have no idea why it was done that way since the setting gets used and directly affects what you are trying to do in your project.  This isn't the first time this has come up.

    Thank you.. That does it.. Yeah.. why do they put another "remove empty layers" and "drop down object" if they are redundant.

    The reasoning is that there are no empty layers when you print with supports.  Granted, there are edge-cases, like when you turn on the supports but the model does not need supports.

    Technically they are two different things. One is how models behave on the buildplate in the Prepare tab. The other works on the generated toolpaths.

    Noticed that Cura 5.3 breaks the way most 3D printed airplanes get sliced.

     

    Cura 4.3 breaks Eclipson (& others) continuous mode when there is for example 2 bottom layers.
    So far I found no setting to fix this except Spiral mode which removes features. It could be related to the "Fixed the order in which concentric top/bottom patterns are printed" change.
     
    May be an image of text that says "Cura 5.2 Cura 5.3"
    For context, especially for LW-PLA, it's really important to get a single continuous line for each layer with no jumps in possible. Ideally there would be a Spiral/vase mode that doesn't remove the internal structures however so far it's mostly achieved in Cura by setting 0 infill and having some rather special STL.

    Hey @Wernight,

     

    That's a super interesting model. We see that in the Variable Linewidth Engine that Odd Walls aren't always closed, which results in lines being interrupted where they weren't in 4.x. Our developers are looking into a way to improve this behavior. This model would really help with the research. 
     

    Do you have a project file for us? It contains the printer and settings we need for troubleshooting. 

    To save a project file go to File -> Save project.

    There are some very cool ideas in this release. Using TPU for moulded in feet is something I'm looking forward to. Those sticky silicone feet work well it they stay put... But it is not always the case.

    This problem has been reported on GitHub a couple of times.  It isn't the only problem with the Machine Settings dialog.  You can't change the shape of the build plate either.

    I am looking for away to assign different z offsets or starting layer heights, to each nozzle / toolhead. I am using an IDEX printer and this feature would be very useful when doing two material prints like PETG and PLA.  PETG does not like to be squished on the first layer nut PLA does.

     

    THis could also be very useful to fine tune the height two different heads.

     

    Presently both of these items are available for the to extruders but they a linked together so you cannot change one without changing the other.

     

    THank you

    Cura can not mix two layer heights in the same layer. Doing so would risk having the nozzle collide with previously printed parts of the same layer. Theoretically, you could "sort" the layer parts by lowest part first, but that is not something Cura can currently do.

    You would have to hand code it.  That may or may not be difficult (depending on things like Z-Hops in the file) as there may only by one or two Tool Changes in the Initial Layer.  There are other considerations though.

    The problem AHoeben mentions will probably come up.  If there is support on the first layer and that support is PETG then the support would be taller than the model and Cura always puts down support first.  If the nozzle were to switch to the lower PLA Z setting then it could hit the support.

    A fix for that would be to print the support last.  Now you are re-arranging the entire first layer and hand coding transitions and travel moves.

    I think that the second layer would also be a problem as the thicker portion of the first layer would eat into the thickness of the second layer causing what amounts to over-extrusion as the second layer gap isn't as tall as it should be given the amount of plastic planned for the extrusions.

     

    There is going to be a compromise but it's a lot easier to compromise the Initial Layer Height between what PLA likes and what PETG likes rather than going in and re-arranging the entire first layer.

    Hello, i am unable to sync Materials with Cura 5.3.

     

    All tested an reseted without success.

     

    Then installed Cura 5.2.2 and all works great.

     

    Is this a problem of Cura 5.3?

    Unfortunately 5.3 install copies all my configurations from 5.2 Beta, but says they are corrupt and it will not open.

    %.2 Beta continues to work fine. I tried manually copying all the config files from 5.2 to 5.3 folders, but it persists.

     

    It's 5.2 for me!

    @cdr-automatisierung What is happening exactly? Could you show the cura-logs? We might be able to diagnose the problem. 

     

    @nickramsey It could be that you're running into this:

    - Fixed a bug where the machine definitions could not be updated
    

    This is a line in the changelog for the upcoming 5.3.1 patch, which will be out this week hopefully. (Which took a bit longer than patches in the past, due to issues with our translations.)

    Material interlocking enables truly unrestricted multi-material printing

     

    Material interlocking is a new feature in this release with the power to unlock a huge number of exciting applications. To find out how, let's take a look at a printed part:


     

    TyOd9mpeXBKU3wzIFdAH26U1X3OqMReZ7XdZUDq_7E3fyaPIsyvzca0snHHJstu_gXpE2RgU_X-OhHjB6j4fs6NY-2A5J_otbSE5V1vneOL3s0OmBsm0AMrRiqdJTQAEiSYppMUm6ag2QCrRV1Xbn-wfIfyBPmdQN4uQGMiqK_qDCaQd2SYSTXdAWhE-gqv8xeu-dKQxvPXbmQSqLM6-ciVDYER40a5sz29FPJj1S7IxwzqMU-drZuE4oBKoBppLkkhii7-1tyCoqLBdTPQWa-hcFnQyqufzVwlf9YtwFHLfXI

     

    This adorable clip was designed by our very own Mariska Maas to show off the potential of material interlocking and can be found on Thingiverse. At first glance, it may not seem all that exciting, but there's a lot more going on than meets the eye. 

     

    Firstly, it’s functional. This print can be used as a working clip. When squeezed at the bottom, the teeth will open and when released they will spring shut. The reason is that the print was made using two different materials. Specifically, CPE and TPU95A. CPE is a rigid material and it was used for the green prongs of the clip. TPU is flexible and it was used to print the black hinge (and the less functional but still cute eyes).

    Give us your feedback

     

    I used this technique to make new end stops for my chairs. The stops are 30Eur for a chair and they are made from thin hollow plastic that wears out in no time. A copy with TPU on the bottom should be tough as nails and last a life time. Let's see how the interlock lasts. The left is the printed version. On the right is the factory model.

    Have you tested Cura 5.3.1? A typo was fixed specifically in that version which affected that.

    AFAIK, you are just supposed to pick Marlin for Clipper-enabled printers.

    So... I'm an absolute greeny when it comes to 3d printing. My first attempts with ABS went horribly wrong. After using some glue stick things were a little better, but despite using a climate chamber and having a door on my UM3, the parts still warped. Maybe it didn't help that the part was quite big.

    IMG_20230422_222644906.thumb.jpg.fcd5a97908d42b37a74ee4e2b5362421.jpg

     

    During one of my other first attempts with PETG I noticed that the stuff stuck to the glass sheet like the proverbial child snot to a wool jumper. This brought me on an idea. If I make a raft of 0.4 or 0.6 PETG and interlock it with the ABS, how will that work? Well, it is going very well indeed! The print is only half way, but showing no warping whatsoever. Is this a possible second alternative for the interlock? Below is a photo of the start of the interlock.

    IMG_20230422_113037132.thumb.jpg.0959074918c192be6d73077b9b4be059.jpg

     

    So the part is completed and it is looking good! Sure I know that ABS is the devils hair and all that. It is smelly and it is a cantankerous temperamental material. In tests it fails to prove real strength. But... Well... It is cheap and I happen to have ended up with a decent supply from various online purchases. This might be my savior to put all that ABS to good use. 

     

    The results are very good indeed! The bind with the glass sheet was impeccable . The final product showed virtually no warping. Removal of the interlock layer is a little more work, but it is also doable. The final part looked OK.

    IMG_20230422_222651169.thumb.jpg.e6e514f827dfecf11a7bebe62b2e16c1.jpg

     

    The raft did not detach in one piece , but it is sacrificial in any case.

    IMG_20230422_222624887.thumb.jpg.d33468a44372665c1e4b636f5f5afabc.jpg

     

    IMG_20230422_222710214.thumb.jpg.a63e63bbc17c9cd21ed669d03b7b9267.jpg


    In the image of the bottom it is clear that the first layer of ABS had a few strands that detached. This is because no glue or spray was used. The bind was very good, however. The images below show virtually no warping compared to the ABS only print.

     

    IMG_20230422_222743213.thumb.jpg.591f48293a14c5f4bd457a87877ad41d.jpg

     

    IMG_20230422_222808968.thumb.jpg.5b36eb898c909b9b196605b198fc0dae.jpg

     

    One little bug I noticed was that the slicer will crop the brim for the primary filament if it exceeds the perimeter of the print, but if the brim of the secondary material exceeds the print boundary, the slicer produces gcode that the printer reports as going out of bounds.

    I would like to point out that the sharpest corner function has severely degraded in this version of cura. 

    Here is what it looked like in 4.13.1

    image.thumb.png.126ac7ab1e8d484b591d26929cbfa1d3.png

    here is what it looks like in 5.3.0

    showing both the smart hiding and hide seam results. It makes me rather sad because I love 5.3.0, it's so much faster, but on rounder models, it looks much worse even than shown here.

    Yes it's new, and I'm the one to blame. 😆

    The default value can be set in Preferences » General » Viewport behavior » Automatically drop down models to the build plate.
    This global setting has been there for a long time, I only added the possibility to change it per object. It is strange that the unticked value was forced on you during the update, this shouldn't have happened. Any body else got this issue?

    Hey @Piezoid and @prd0000,

     

    This report reminds me of this issue on Github

    Can you try the following:

    1. Turn off "Generate Support".
    2. Go to the Mesh Fixes settings and turn off "Remove Empty First Layers".
    3. Turn on "Generate Support"

        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
