GCode error prints always fail, weird errors in GCode always at layer 50 (multiple files)


Recommended Posts

Posted (edited) · GCode error prints always fail, weird errors in GCode always at layer 50 (multiple files)

All of a sudden I'M having a prints *always* fail at the same point about 10mm up, the print head then lifts up 5 inches or so, squirts out some filament then says its finished all OK (many many hours short of the expected time).


This has just happened after a year or more of never seeing this issue with Cura/Ender3v2, same on every slice/print now


I'm pretty new to this but...

I loaded the Gcode file into https://gcode.ws/ and yes I can see a weird artefact at layer 50 (image 1 attached), re-sliced multiple models multiple times with multiple different settings and I now always see that artefact. I analysed an old Gcode file that I know works and it DID NOT have that artefact at layer 50

That could be a 'red herring' but I don't have any other ideas, help please


I attached a gcode file from the print that Im trying to do and has failed 5 times at the same place


Trouble shooting steps on top of what's listed above:

I upgraded Cura to the latest version and it didn't make any difference

Installed Cura  on another fresh PC same thing, still the weird artefact at layer 50



Ender 3V2

Cura latest version

    Here is the gcode file you posted.  I don't see anything weird in it other than it's not the one you had analyzed.  Have you formatted that memory card lately?  It needs to be done every once in a while.

    Here is the one you posted opened in Cura.  I read it into AutoCad as well and that one looks just like this one.  The lines on the left are your purge lines and the angled line is from 0,0,0 to the start of the skirt/brim.  There is also the wipe-out move at the end of the print.  I think there is a better than even chance you have a bad sector on the memory card.

    Thanks for that, further testing indicates it is *not* the Ggode although there is still that weird artefact at layer 50 on some but not others. I have had it reliably printing now regardless for some time. I didn't really do anything except stick with one 'known good' card. Have purchased some new ones as well. I will pay close attention to which card does what if it happens again and post back here but yes sounds at this point like you may be right on.


    Thanks so much for taking the time to help

      • 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
