  1. Hi Daid,

    Well change of plan today I can test:

    You are my hero. Yep that solved the issue. I can now use the layers function again. Wow Python is tab sensitive. I am a C++ programmer I would have never guessed that. I hope you keep this change in the code for the next release of Cura. Since I patched my version I use that for the time being. Nice that you had this backward compatibility already in the code.

    If you need someone to test on 'old' computers I can do that since I have the right hardware. Just mail me.


    You can also apply this patch just add one extra tab to the 2 lines of code that Daid pointed out and your system can run again.

    Guess I am the first one to have a fix in Cura before having the printer, still waiting.




  2. Hi Daid,

    I will test it out on Wednesday evening. Is it a matter of changing the .py file in the current cura installation? If that is the case it will be simple. Or do I need to compile something after I have changed the openglHelpers.py in order to get the change in?




  3. Hi Daid,

    Sorry for the late reply I was at the ulti evening..

    It seems like that the detection of old hardware does not work. The error I got with linux was the buffer pointer which is used in the new case. Question what has changed between 14.01 and 14.03? I can offer to help since I seem to have the hardware that you don't have.


  4. I have been looking into cpu gpu specs and unfortunatly Cura does not state its recommended graphics requirements apart from 2Gb Ram and Pentium 4 or Core 2 spec there is nothing on the graphics. The Atom processor that I am using does have simular or better instruction set as the pentium 4. But that does not specify the opengl that is used. Apparently opengl 1.5 is required but also some form for the shaders which version I don't know. It would be nice to know what to expect and a littlebit of the roadmap. If I am going to buy new hardware I don't want to be faced with new features that require something that I don't have.

    Drayson I am glad that I am not the only one (tianks for the feedback), it confirms that it is not due to some stupid missing software update (I also tried upgrading the driver but the intel scanning for updates does not complete it hangs for hours). And yes what is going on with windows XP makes me sick so you are right about the technoligy push.

    For example will the intel HD 4400 graphics controller good enough for some time to come. It supports opengl 4.2 on windows and 3.3 on linux. It can use shader model 5.0. Or do I need to used a additional graphics chip AMD or Nvidia? What would be required??


  5. I try to design a holder for some glass (transparant plasitic 0.25mm thick) that I want to use on my railway track (H0 scale). So I need 2 objects. 1 object where the 'glass' falls in and an other to go over the glass that I glue to the outside ring. So in principle I have 2 boxes that need to fit into eachother. The wall of the outer box is 0.8 mm so I would compensate the size of the inner box with 0.8 mm (left and right) or should I allow more room? Should I allow 0 mm spacing in between or something like 0.1mm? I still need to glue them together and the less room there is the better.


    I will plan to print it with PLA first. If that does not get the desired results I will use ABS (easier to glue).


  6. Hi Andrewwib,

    Yep it is Design Spark Mechanical. The kids will be able to learn sketchup quickly. My kids did. But drawing something that is printable is different you must make sure that things are connected and that is quickly overlooked. I am playing arround in design spark and it takes a little more time than sketchup. But the ease in which you can make rounded corners which improves printability blows my mind. Making rounded corners in sketchup is possible but modifying them later is a mess.

    I don't know yet how quickly the kids can draw something printable since I am still waiting for the printer.

    Printing from a library is not my thing. I will be making mechanical parts and those always

    have custom geometries.

    But my daughter will probably like to print earrings and those you will be able to find.

    So it depends on what you want to print what software you use.

    Good luck in experimenting:)

  7. Hi all,

    First of all I don't think it is a deliberate plan. Programming with backward compatibility in mind is a not a simple thing. Cura has its reasons to use performance optimized code. For that you have lots of possibilities to achive your goal. Without realizing it you quickly use something that is not possible in older hardware. The question is how far and how much time do you want to invest in these issues. It usualy starts with a small thing but 2 years from now that small thing is messing up your code al over the place. That part is the time consuming part. I don't know if Ultimaker wants to invest in these issues. For my work I also sometimes need to make changes in code that is well over 10 years old. So i know how nice that is. None the less it is a pitty when you have this well functional machine and can't upgrade it anymore.

  8. I guess I reached the end of my faithful netbook. It is a ASUS 1000HE with an Intel Atom N280 with GMA950. This only supports opengl 1.4. I can't use the Layers function anymore. On windows the program was just hanging. On Ubuntu it gave me an error message noting that the glBindBuffer was not available. I looked it up and it is supported since opengl version 1.5. So now I don't have the Layers function anymore. It did work on Cura 14.01. In that version the Overhang function was not working due to missing shaders. I could live with that but not having the layers will be a major drawback.

    Up to now I have been very happy with my old netbook, small/power efficient and all the performance I needed. Not anymore. I did quite some work with sketchup and I started using DesignSpark.

    Any suggestion on preferred hardware/amount of memory?


  9. Hi All,

    I also ordered on the 13th feb (oh oh that is not a good date). And yes the status of the ordering system is a bit difficult. In principle it could help if you can see which orders will be delivered so you can see how long the queue is so you can predict for yourself how long it is going to take. The problem with that approach is that you actually show the amount of systems that you are shipping/producing. This is typically company confidential information but I know companies that do that and you can see the waiting list. A good example is


    No I do not work for that company I am just a happy user of their product as I hope to come with a Ultimaker.

    They have a similar business also a high tech product with a long lead time. At any time you can see the order backlog and the waiting time is even longer....

    I am also desperately waiting for the delivery but I know high tech products do take time to make with all kinds of unexpected hiccups. When I ordered I knew that delivery was planned in March it was on the website at that time.

    In the meantime I will spend on preparation for the time the Ultimaker is there. I even found the optimum aluminum for a heated-bed. I also try to improve my skills in DesignSpark since it looks like a promising tool. Next year I forgot that I had to wait for some time.
