Slic3r + ultimaker 2+


Recommended Posts

Posted · Slic3r + ultimaker 2+

Hi everyone my group just picked up a new 2+ for prototyping mid size injection molded parts. Anyway we are experienced with 3D printers but new to the Ultimaker world. I have found the slicing done by Cura to be totally unacceptable no matter what we do with settings. It depends on the parts but is really seems to have trouble with parts that combine thin shells and thicker sections and it creates G code that is totally insane with random movements. I used Slic3r with my Makergear M2 and found it to produce much nicer parts so I am trying to get it running properly with the Ultimaker.

I have put the two config files and some example photos in the linked folder. I think anyone should be able to view it.


The slic3r settings work better than Cura other than the total lack of top and bottom skins. I don't understand why it is doing this and it was never an issue with my M2. I have tried reducing the layer height to 0,1mm so it will have enough thickness to create the layers but this didn't make any difference, I also tried printing 100% infill which also did not help. I can't use the special thin wall functions as the whole part is not a single layer.

    Do you have examples of stuff you couldn't get to work? What version of Cura did you use?

    If you could share these with us, we can fix them.

    The objects in your pictures actually look like as if they are printed with faulty material.

    Can you please advise the settings in Cura that you are using - that will help us considerably.

    1. in Cura sink the part into the print bed say 1mm - Cura advanced menu\Quality\cut off object bottom - set to 1.0

    2. maybe your nozzle to bed measurement is too large - have you double checked this?

    3. As an Ultimaker beginner do not set your 1st layer resolution lower than 0.300 Cura advanced menu\Quality\initial layer thickness - set to 0.3

    Looking at the vertical walls where you have the poor finish, what is the thickness of those walls in your modelling software?

    Oh, good one. If i recall correctly, this is one of the main differences between Cura and Slic3r. If slicer sees a wall that is thinner than the nozzle size, it will print a wall at nozzle size. Cura on the other hand will not print that wall (as there is no real way of doing 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
