Why is the printer doing this on the first layer? (pic)

Posted · Why is the printer doing this on the first layer? (pic)

My printer seems to be printing the sides thick and the middle (front to back) thin. The pic will probably explain it better than I can.


How do I fix this?


Thanks in advance,

    First of all the difference is pretty small and I think most people wouldn't care.  I mean the final part should look fine, right?  Well maybe lower/tighten all 3 screws just 1/3 a rotation to get the bed a little farther from the nozzle.  But the final part should look fine I think.  Just because the bottom layer is a little thin doesn't mean the whole part is bad.


    Anyway what is causing this is almost certainly glass that is not flat.  Ultimaker uses tempered glass (not certain why they do this) and tempered glass tends to be thicker/higher in the middle just like this.  You could just accept it like this or you could ask your reseller for another piece of glass.  But they are all like this to some degree.  Some glass plates are better than others.

    As @gr5 said, this is most certainly due to the glass not being perfectly flat. It seems to happen a lot, I guess UM should try and get better glasses from another supplier.

    Anyway, you can try and call your supplier to have the glass exchanged, or, you could try to print on the other side of the glass. I bought a second glass bed, and the second one was less thick in the middle on one side than the other, so flipping it over solved my printing troubles.

      • 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
