    Quality printing problem

    in UltiMaker 3D printers

    Posted

    It look like a problem with the z axis to me

    maybe you need to clean and lubricated both the Z thread and the vertical shafts

    One other thought, depending on your feeder (I have a BondTech feeder) sometimes the internal feeder gears benefit from cleaning

    I have feeder bondtech, and I I cleaned and lubricated the z axis.

    print size with UM2+

    You have "brim" turned on, this will reduce your effective print size by 2x the brim width at X and Y since it needs space for the brim.

    The same object works without brim:

    Thanks a lot, I realized it too late.

    I know its asking a lot, but that does kinda negate the purpose of 'layer view': to spot issues in your print before it prints. How do you know know which issues are real and which aren't?

     

    You don't. This is why i was not so sure we should have this feature. But all the other slicers had it and at some point we also had to participate. Because if we don't, people keep using the lack of a "realistic" rendering as an argument why Cura is falling behind.

    If you want a perfectly right layerview, it's going to take a loong time to build. You would need to take a whole lot of physics, material flow, deformation, etc into account.

     

    Thanks

    Polymaker filaments

    in Materials & profiles

    Posted

    The shop where I bought my UM2+ recommended those filaments from Polymaker so I started with almost all colors from Polymaker having Polyplus as well as Polyflex. I only started printing recently so don't have much to compare with. I can only say it's definitely producing decent prints. At least, the Polyplus because the Polyflex is totally different. I might not yet have found the most ideal settings (50mm/s, 225°) but to me it seems that has some limitations. You cannot use support very well because it just doesn't break well from the object you're printing. Any slight overhang is not printed nicely and that's the same for other details. I'm enclosing couple of pictures where white is Polyplus and black is the Polyflex. Rest of the settings are equal except for temperature which is higher for the Polyflex. Would love to hear from others their experience with Polyflex or other flex in general.

    Thank you for these your important information.

    New printing problem.

    I also have this on small parts, for example on fine text of a few mm height. It indeed seems to be caused by the head stopping for a fraction of a second while retracting, and then moving on.

    I can reduce it but not eliminate it by reducing temperature and printing slower, for PLA down to 180°C or 190°C, and 20mm/s, for small parts.

     

    Thank you, the press seems to me that it was to 203 ° C with the next try to print to 195 ° C
