Filament purge on UM2/2+

Recommended Posts

Posted · Filament purge on UM2/2+

The start Gcode on UM2, that involves filament purge... where can it be changed to become as the UM3 purge, thats much smoother... 

The purge happens long above bed now, with the risk of dragging the blob into the print, when it starts.... how to ? 

When trying to fix via start Gcode trough Cura.... it just duplicates, and runs original purge before the custom made purge....

Could someone please help.

    Two thoughts:

    1) Do you have machine settings set to "ultimaker 2" or to "gcodes".  If you have it set to UM2 then I believe the printer does it's own purge before running the gcodes.  So perhaps that is the issue.


    2) If you are truly speaking about gcodes in the gcode file then it's probably similar to temperature.  If cura sees that you are using one of the temperature variables in your start gcodes then it will not bother adding it's own temperature codes.  I'm guessing it's the same deal with the purge amount.  I'm guessing if you use the purge amount variable (not sure what the variable is called) then I'm guessing cura will skip adding it's own purge code.


    Please clarify which machine setting you are using and I'll elaborate some more.

      • 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
