New S3 auto-leveling issues when printer is warm

Posted (edited) · New S3 auto-leveling issues when printer is warm

Hi,

 

I have a new S3 that is about a month old that is experiencing active leveling issues. If I start a print from my S3 that has been off or idle for a few hours, it passes active leveling and prints without any issue. However, if I then try to start a new print soon after the first print finishes, I will run into active leveling issues and receive the "Difference between detected height of both print cores exceeds realistic values" or "nozzle offset probe failed. Please check the nozzles and bed and try again." Here are two videos that demonstrate the behavior: https://photos.app.goo.gl/jkbp3zm88neK8cei6

 

Basically, the build plate starts moving up to the printhead and stops before even reaching the print head. 

 

However, if I wait an hour or more after the last print has completed and the printer has cooled down and then start the print, it will pass active leveling without issue and proceed to print without issue.

 

Have anyone experienced this before or know of the cause or potential fix? 

 

Thanks

    I have never had the problem where it seems down to the temp of the printer, normally its due to other devices in the area of the printer making interference for the sensor.

     

    Check the wires inside the print head from the sensor board are all fine and that it's plugged into the back of the print head fine (unplug it and plug it back in again). The sensor is the whiteboard you see when you drop down the print head front fan to access the print cores and you will see 2 metal pins in the center of it, check they are all fine and not lose.

     

    If the problem remains and all the wires seem fine, then it's likely best to contact your local reseller who should be able to help.

    Thanks Carla. If I unplug the front fan when the printer is warm, it does seem to pass active leveling ok. I'm just confused as to why it only seems to be an issue when the printer is warm from a recent print and not all the time.

    Hello xiaosong,

    I have the identical issue  with my S5, when I do trials and stop prints and restart short after, then this kind of issues comes up.

    If I start then a second time it will be work in 95 % of cases

     

    Do you still have the issue ?

      • 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
