Big Problem when slicing new file.


Recommended Posts

Posted · Big Problem when slicing new file.

Hi Guys,


After editing my STL file and making a few adjustments here and there i wanted to print out the new version.


When slicing it using Cura, it somehow truly ruins the GCode... 


When printing it all of a sudden starts to create a random circle??


Here is what i mean:


This is the correct (older) one:



Here is the new one:



Here is also a picture of Cura:




Can someone please help me and understand how and why this is happening?

    That circle is the raft.  There is one tab that hits the build plate and the rest of the bottom is elevated.  In order to print correctly it needs support as the main body bottom is 15 layers off the build plate.

    Here is the preview of the "Modified" file.



    Here is the model sliced with Support turned on.  There are 14 layers of raft and support before the bottom of the piece shows up on Layer 15.  I realize this needs a lot of support but when you have areas that start in thin air there has to be something for it to print on.  Air printing never turns out well.




    This is with support turned off.  There is no way that piece starting out in space will print correctly.  A lot of that overhang has the same problem.
