Feature request - Connect raft lines

Hello. This is how the bottom raft layer looks now on Cura 3.6:

All of these inner lines are printed individually so after each printed line there is a retraction. The middle raft layers are printing using zig-zag pattern with connected lines:

Can we somehow enable "connect lines" feature on the bottom layers to avoid unnecessary retractions and increase bottom raft layers printing speed?

    I'm pretty sure not.  You could play around with "combing" which controls retractions in situations similar to this and see the result in PREVIEW mode.

     

    Raft is rarely used in Cura.  It's an old feature from before people found better tricks to avoid parts warping off the print surface.  Raft is more a last ditch effort.  There are better ways to get your part to stick to the bed depending on your bed?  For example if you don't have a heated bed and are using blue tape - you might not realize that you have to remove the wax from the tape using isopropyl alcohol.  Or if you have a heated glass bed you might need magigoo.  Or you might not be squishing your bottom layer enough.

     

    Anyway, the point is, Cura developers probably haven't paid much attention to raft because probably none of them have ever needed it.

      • 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
