How to improve these prints?


Recommended Posts

Posted · How to improve these prints?

I had some good prints from the beginning but now I had the smart idea to imrpove them even more by readjusting the tension in the belts and the motors. (I was told to tighten the screws on the motor after a few prints.) Now, round objects are not really round anymore. What can I do?

I printed high quality on 200%. (picked the wrong g-code file but did this before with good quality)

    EDIT: silly me

    Non-roundness is probably caused by loose belts. Tighten the belts or print out belt tensioners. One way to tension belts is to wrap chicken wire around the moving axis blocks and stretch the belts that way.

    Make sure to check the short belts that go to the motors.

    Next time you should resize your photos or post links to imgur because I can only see about half of each photo.

    When you say "not round" are you saying you get ovals, or that the circle consists of a bunch of straight sides and thus you get polygons?

    Your photos seem, to me, to be highlighting the second option - that you are getting flats on the insides of your circles.

    This is explainable as possibly a problem in your model. All circles are printed as many sided polygons and perhaps your models just don't have enough sides to hide the flats. I've no idea what a good value is, but I put 100 sides on most circles.

    By tightening our belts your printer could be more accurate and thus better able to render the corners between flats, where in the past they just rounded out due to inaccuracy.

      • 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
