loops and perimeters inside out?


Recommended Posts

Posted · loops and perimeters inside out?

I was having what I thought was a hardware problem, but now I think it's a misunderstanding of how the slicing works.

I tried to print a box with some holes pre-drilled in it, but got rough patches on the outside of the box (example image here -

looking at the gcode, I see the outside of the box is red, except where these weird marks are.. where it's green.

I think green is loop rather than perimeter? but why are the loops and perimeter getting turned inside out like this and how do I fix it?

    I've seen it happen before, and I'm still not sure if it's my mistake in the preview, or that Skeinforge does something strange. However, the path is still correct in this case, only the type seems wrong.

    did you see the first picture of how it prints tho? where the green is on the outside the print becomes very rough - this was the reason behind my question the other day about loops -> perimeter -> infill vs perimeter -> loops -> infill.

    I'm not sure the preview is wrong, I think something to do with the slicing is wrong (perhaps because it's confused by some aspect of the model?)

    I mist the photo, sorry.

    I've seen roughness like that before, for me it was the extruder that was slipping at higher speeds.

      • 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
