Tell Cura to over extrude on layer 1 through 20

Posted · Tell Cura to over extrude on layer 1 through 20

Is there any way of telling Cura that I want layers 1 through twenty at 130% extrusion? Layer 0 must be at 100% then switched to 130% @ layer 1 and print at 130% until layer 20, then change speed to 80% @ 100% flow rate until layer 30 where it can start running at it's normal speed of 100% @ 100% flow rate.


Thanks in advance.

    Without a custom script you would need to do it manually.  M220 S100  would set the Feed Rate to 100% and M221 S100 would set the flow rate to 100%.  You can use the search function in Notepad to find the start of each layer you want to change Feed or Flow at and insert a line.

    Search for "layer:1" (must have the colon)

    Just below the  line ";layer:1" add:

    M221 S130

    Search for "layer:20" and just below that add:

    M220 S80

    M221 S100

    Then at layer 30:

    M220 S100

    GregValiant, thanks for the info. I was thinking that's what would have to be done but wasn't sure of the code to insert. I was searching last night for the codes to use and just couldn't find them since there are so many sites that have them but either don't explain what the code is or say it may not work in the software your printer is using.


    Thanks again.

        (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.
