Print speed set to over 800%


Recommended Posts

Posted · Print speed set to over 800%



New to 3d printing.


Have created a few gcode files and most things have printed fine, but a couple  of models have gone haywire. when used Cura to genrate gcode files and tries printing them, the printer screen is saying speed of over 800% and the printer goes haywire.


Some other projects are fine.


Am i doing something wrong?

    This has come up recently but when I looked through the posted Gcode file there isn't any problem.  Somehow the printer is jumping the feedrate to over 800%.  What printer are we talking about here?


    If you open the gcode file with a text editor (like MS Notepad in Windows) and search for M220 I'm sure you won't find one like M220 S810 which would tell the printer to change the feedrate to 810%.  M220 is the only Gcode command that alters the feedrate percentage (the Global feedrate) of the printer itself.

    There is something going on the printer or firmware that is causing this.  As I recall, even a firmware reset didn't help that other poster and when I printed their gcode file with my E3Pro it printed just fine.

      • 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
