Extruding/rectracting with Cura


Recommended Posts

Posted · Extruding/rectracting with Cura

Hi guys, I am new to this forum and I have been using Cura with my non-ultimaker 3D printer for the last couple of weeks. I found it is far much better than repetier in terms of ease of use, slicing speed, stability and print quality. There are only two minor problems I faced :

1. How can I extrude/retract filament directly using Cura? Currently I have to use repetier to extract/rectract and then use Cura for printing.

2. The print time showed was not accurate. For example, Cura shows the print time is 8 minutes but in actual it took half an hour to print.

Hope you guys can help me with those problem, thanks a lot...

    a non-ultimaker using cura.

    I suggest to manually extract/retract at the beginning before printing. i call that handpriming

    cant go easier than that.

    but i also missed to have that feature. i came in from replicatogG.. there was a nice controller window to access everything the printer can do.

    however on a ultimaker with controller you should be still able to do this without touching any cogwheels.

    but you cant move the z-plattform that way

    since you have a non-ultimaker thats a problem X)

    i would love to have a stable Cura implemented in Repetier as a slicer...

    lets hope for the next release..

    Can't you just turn the extruder gear by hand? On the UM it's a very large gear on the back of the machine and it's so much better to do by hand than using software as you learn a lot. You get a feel for what kind of pressure is needed to push through a given temperature of filament.

    As far as speed goes...

    For very small parts (smaller than 1 inch across) it's going to be way off. Cura just adds up all the segments and assumes a constant speed with infinite acceleration and deceleration.

    Is it possible that your machine has a "max XY" speed that is much lower than the default cura speed?

    For parts larger than 4 inches across, cura tends to be very accurate guess for the time because it travels long distances per segment and has plenty of distance to get up to full speed. For parts around 2 inches it can be off by a factor of 2X and so on.

      • 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
