Stringing

I am using Cura to slice files for the Qidi Tech X-One printer.

I can't seem to get the stringing under control.

I have tried a lot of different combinations of settings. See the link below.

Test #6 was sliced with Simplify 3D and it looks perfect. Someone from Thingiverse sent me the G-Code. He said it was the stock S3D settings, nothing special. He is going to send me screen shots of the settings eventually.

I believe Cura can do it. I think I just don't have the right settings. I want to use Cura because.... well it is free. And it has some infill settings that S3D doesn't have. And it has the Alternate Extra Wall setting that I think is really nice.

Thanks in advance.

    I ran another test based on the setting recommended by this article: https://ultimaker.com/en/resources/19504-how-to-fix-stringing

    It did not solve the problem. I killed it mid print because one of the towers fell over and nothing good was happening anyway.

    Blah.

    Ok, in case anyone still cares...

    Test #6: Another X-One owner sent me his g-code file from S3D. PERFECT results. So now I know MY x-one can do it.

    Test #8: I slowed the retraction speed way down. Beautiful parts with a beautiful "angel hair" wall.

    Test #9: I turned the heat down to 180c. Not so good.

    Test #10: I upgraded to Cura 2.6.1 and ran basically the stock PLA settings. One of the towers fell over and there was minimal blobs.

    Test #11: I turned on Coasting. All the towers stayed up, but I think the blobbing got a little worst.

    Test #12: I turned on Z-Hop. Perfect "angel hair" wall again.

    Blah. I think I will go back to the #10 setting and fiddle with some stuff, but leave Coasting and Z-Hop off.

    Test #15: wsdukai sent me screen shots of his S3D settings. I tried to match them as close as possible. This is probably the second best result so far, behind the S3D g-code.

    I think the big differences were the reduced flow rate (extrusion multiplier), and the "retract before outer wall" turned on. I might run some tests to isolate them.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        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
