why cura preview stick out too many lines

[caseyxng 1]

I was try to print a temperature tower. But the preview in Cura looks awful. I've tried other 3d files. They all have the same problem. Cura worked good before. But it suddenly become like this. Is there any configuration I didn't do right?

That looks like some graphics bug.  I don't think those lines are actually printed.  Try a different computer with different graphics cards or graphics drivers.  Usually temperature towers are gcode files only?  Not STL files?  If so then you don't need cura to be involved at all.  And the gcode files are customized for certain printers.  Typically.  This is because you can't set the temperature in an STL file.

 

So:

1) Is this a gcode file you got?  If so then just try it out.

2) If not - how are you planning to change the temperature at each level?

Yes, I restarted my computer and the lines are gone. Thank you!
