  1. When the object is sliced and the gcode created, what is the speed setting in the gcode? Is the speed something I can modify in the gcode?


    I ask because no matter the speed I select in CURA, the prints are always printed at the same speed. To reduce the speed I have manually reduce the print speed on my machine.

    cura 3.1 crashed and now won't start up any more.  I tried reinstalling it but but that didn't work.  I cleaned out the registry prior to re installation.


    any advice would be most great full. 


    many thanks 




    The board has multiple threads about cura 3.1 issues, perhaps it should be pulled, and beta tester released. So my advice is uninstall 3.1 and go back to a version of cura that worked for you.

    I don't know if anyone has asked, but if you are using the Layer view, it slows down everything drastically.

    Do your tweaking while in Solid view, and turn Layer view on after you make multiple changes, then back to Solid again.


    Please see the video here , that video demonstrates the issue. The slowness is not about layer view, the slowness when you change a custom parameter, it will take 6 to 7 seconds before you can change another parameter. This slowness with changing parameters happens even with auto slicing turned off. One hypothesis is that when a change is made to one custom parameter, a software change is made to other parameters with the intent of reducing the slicing time.

    I haven't tried it with my Macbook, but with my Windows machine, disconnecting from the network enabled it to work like a champ. You could give that a try to get your settings right, reconnect and send to the printer.  If you haven't already gone into the plugins menu for customizing Cura and deselecting Octoprint, I would do so, as it made a substantial difference for me.


    I wish it were that simple for me.

    Not quite true. We don't handle shaders in the same way. It simply shows that it can be fixed, not how it can be fixed (or if we will be able to figure it out). There are still tons of variables that could cause it.


    Would it help to narrow down the issue(s) by focusing on the overall sluggishness? It takes almost a minute for cura 3.***** to fully open. Then without a model loaded, there is about a 7 second delay between mouse clicks and cura response.

    hi... just want to add my experienced with cura 3.XXX to this discussion before its overlooked
    follow link ... but basically on a clean windows 7 x64 install i experience  a slow, sluggis responding version of cura 3.1 ion my system.... i wished i could be of any help to solve this.. but i'm not a programmer :-/   
    (using multiple kinds of printers UM2 / UM2+ / UM2 Extended / Witbox)

    @paulbeumer:This is an issue with a specific set of Intel drivers. Upgrading to a newer version of the Intel HD Graphics driver should fix it.


    See https://github.com/ultimaker/cura/issues/2068




    I have AMD processor and experience the same sluggish issues, on board graphics card is ATI Radeon 3000. Just installed a new video card 30 minutes ago, and still have the same sluggish issues.

    I have no experience with installing OctoPrint on Windows. The output you posted suggests pybonjour can't find a bonjour specific dll. You could try installing Apple's Bonjour implementation for Windows, which I guess would come with that dll. https://support.apple.com/downloads/bonjour_for_windows


    Out of interest, why don't you just do

    pip install pybonjour



    Anyway, OctoPrint should run just fine without Bonjour, you just have to add a manual instance which is slightly less spelt out in the interface than adding an instance with bonjour.


    I thought about asking about Apple bonjour as I have seen that process in Task Manager on my other system


    As for why I did not pip install pybonjour....because I haven't the slighest idea of how to do that, nor where to do that. At the moment I suspect that it would be:


    cmd prompt

    and then get into the venv c:\octoprint pip install pybonjour


    So I ended up with this:

    (venv) C:\octoprint>pip install pybonjour
    Collecting pybonjour
      Could not find a version that satisfies the requirement pybonjour (from versions: )
    No matching distribution found for pybonjour




    I will try apple. But there is another issue, which I suspect has to do with granting network access.

    OctoPrint normally uses a service named "Bonjour" or "Zeroconf" to announce itself on the network. This is used to populate the list of "instances". Since this list is empty for you, I am assuming Bonjour does not work on your Windows setup. So you have to Add a "manual" instance. For most people Bonjour does work, and they don't need to go through the hassle of adding a manual instance.


    based on the lines in the cmd prompt it looks like pybonjour did not install with python.

    I am using Cura to slice for an Ultimaker 3. For some reason, Cura becomes unusably slow (having to wait for a minute or more between mouse clicks) when I have it connected to the internet. As soon as I disconnect my computer from the internet, it returns to the normal speed. I assume this it has something to do with Cura trying to connect to a service and getting a bad response? Either way, this issue happens on both my macbook and PC, as well as across Cura versions (I have tried 2.3, 3.0, and 3.1). 


    Disconnecting from the internet to use Cura works in the meantime, but it means I cannot view my printer over the air, nor send prints wirelessly. It would be nice to have this functionality.



    Did you turn OFF automatic slicing? Turning that off only helped a small bit. Cura still bogs down with every mouse click, even when a model is not loaded.

    Well, I think the conclusion is that: 1) Cura is very slow on PC and has been for while, 2) The 3D navigation is clumsy and not up to normal 3D standards and both need improvements.


    I will speak to conclusion 1.


    Here are my specs:

    AMD Athlon IIX4 640 Processer 3.00GHZ
    8.00GB RAM (7.75 usable)
    64-bit operating system, x64 based processor
    Win 10 Pro (authenticated)


    Cura take 1 minute and 40 seconds to fully open.

    Auto slicing is disabled, NO model is loaded, and it takes 7 seconds between any change in an parameter under custom before another parameter can be changed.


    So I agree with you that Cura runs slow

  11. If Ultimaker cared about its products and the users, then ultimaker would provide instructions


    To your comments I identified the problem in the first post. Specifically “and then get some message about selecting an instance and some message about host, ports, paths....What in the world does any of that mean?”


    As for having to manually add, There is Instance, Host, Port, and something else. Yet I cant find anything about manually adding an instance, that does not first assume the user is using rasberry pi.

  12. Your cooments are not relavent to point that...If Ultimaker cared about its products and the users, then ultimaker would provide instructions. 


    To your comments I identified the problem in the first post. Specifically “and then get some message about selecting an instance and some message about host, ports, paths....What in the world does any of that mean?”


    Your first comment ignored the issues I asked specifically about. 


  13. Thanks for the reply. The Video did not help. The video does not help because it is does not address a single issue raised in the first post. I have no qualms with octoprint.



    I open cura and manage printers, connect to octoprint, and then get some message about selecting an instance and some message about host, ports, paths....What in the world does any of that mean?


    I select connect to octoprint.....there is NOTHING THERE., I click refresh several times....and yes I am connected to octoprint via localhost:5000. I select ADD, then I am faced with a whole mess of things I have absolutely no clue as what any of it means.


    Ultimaker "ships" cura with a 3 party capability, it is not the responsibilty of you ahoeben to make a video of how to connect Cura 3.1 to octoprint....that responsibility if Ultimakers. Why? Because Ultimaker ships cura with octoprint capability builtin. Ultimaker should at a minimum provide sufficient instruction on how to utilize that capability. And if attempting to create the  instruction, Ultimaker realizes it does not work, then that is were you step in. 


    Is it really too much to expect? To much to expect a company to show consumers how to use its product? Or should I expect that in this day and age, companies can't be arsed to demonstrate their products?

  14. Could someone direct me to a tutorial on connecting Cura 3.1.0 to Octoprint? I have Octoprint installed. I open cura and manage printers, connect to octoprint, and then get some message about selecting an instance and some message about host, ports, paths....What in the world does any of that mean?


    A message to Ultimaker. Many people, like me, find your software and use it. We are inexperienced in almost all things software related. Somehow, I managed to install python and octoprint via cmd prompt without activating the launch codes for all nuclear powers. How I was able to fumble through the cmd prompt install process is that Octoprint created detailed step by step instructions. As a consideration to users like me who, like John Snow, know nothing, please consider creating official instructions for updates when major interface changes are created in your software. All I could find using internet searches is how to with cura 15, or cura 2.7, videos showing connecting to Octoprint. Thanks.
