Nozzle Height Difference Error


Recommended Posts

Posted · Nozzle Height Difference Error



Tried to with my S5, when the active bed-leveling program was run, the error of 'nozzle height difference is outside of realistic values' (paraphrased) came up.


I have tried:

- Swapping printer cores (AA-AA, AA-CC) combinations

- Thoroughly cleaning the bed (acetone, IPA)

- Manually re-leveling the bed

   - ER45 came up during this process, looked at everything, seems ok, I re-seated the sensor plug anyways. The error hasn't come up again and it didn't come up when doing the XY offset calibration during the active bed-leveling portion.


I don't know what else to try. Core 2 is decently below Core 1 when activated (nothing abnormal) and high above when de-activated.


Any suggestions or solutions would be very welcome!

    Hi, is this a problem thats started after having worked fine or is it a new printer?


    A few things can make the active leveling fail:

    • The manually leveled bed can be done up to tight, when look at the print bed from the front, you want like a 1mm gap i think it is between the the frame and the glass, if its lower back the adjustment off to get the gap and manual level again, then try auto leveling.
    • Electrical interference, from items close to the printer. So try moving any other electric items away from the printer to see if any of them have been behind interference with the S5 sensor.

      • 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
