Circle and arcs patterns in outer shells

Hello, I have a WASP Delta 2040 printer and in all my prints there are circles and arcs patterns emerging.

Here are some photos:

In the photos above you can see the arcs.

In the photo above you can see the circle on the left side.

I saw that there are other users of this 3d printer that have the same problem but couldn’t find any information about this. If there is a troubleshooting guide about this please share it.

The printer is in service now so I can't test anything, but any info would be appreciated.

Thank you for reading.

    I have had the same while i was printing a violin. It has to do with your fan settings. I think the tilting of your head will probably cause these problems. But since we do not sell the type of printers you use I am not sure. But it is something you could try.

    The wobble of the fan would cause ripples or some kind of noise on the layers but I don't think it could do a circle or arc... but I could be wrong.

    Did you have the same problem on a delta printer? What printer?

    That circle pattern is - well - very interesting! I've never seen that. I would ask on a delta forum as I suspect all of these are related. The arcs - is the center of the arc pointing towards the hinge point of one of the delta arms?

    The wall patterns might be somehow related to Cura or maybe to your cad software or a combination of the 2 but the flat circle pattern - there's no way - cura just does simple diagonal lines. There is nothing that could come out as a circle pattern there. That circle pattern has to be related to the printer itself.

    I was using Simplify3d for the perimeters. Cura was used for the circle.

    The center of the arc is facing the door of the printer (between Y and X tower). It does a bowl effect.

    The circle appeared between the Y and Z tower.

    I don't have the photo but I saw a WASP Delta 2040 user that had multiple circles on a big print (a football),

    Can you recommend me a forum for Delta printer problems?

    Thank you for the support.

    That guy registered 3 years ago but posted last may. Less than a year ago. The first 2 answers make a ton of sense to me and is probably why he never posted again saying "it can't be answer A or B because ____".

    Do you have auto leveling because that could explain it. The circles could be centered where the auto leveling points touch and these rings are leveling compensation.

    Alternatively I like the second answer as well.

    Sorry about the date, I had a lot of tabs open & forgot wich one was wich.

    No auto leveling on WASP Delta, only manual levening. The circle in my case appeared opposite to Y tower.

    I will tell the manufacturer about the second answer in the forum.

    I think it's a segmentation pattern common on delta printers. More info here:

      • 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
