Cura G-code big Z jump !!??

Recommended Posts

HI everyone. I am new to Cura. I used to use Simplify3D.

This project has caused me big problems.  I had tried multiple times to output STL from my designer and imported them into Cura. I even moved the part to different positions of the print bed and regenerated the G-code. But most time I got a big Z jump at a certain build height. The Z axis just jumped by 10cm and continue to extrude...

 

I am using Creality CR-10 mini and the latest Cura 3.2.1 version.  Would anyone have an insight?  The Project file I attached here made the one on the right. After about 12mm of height, the extruder went up and continue to print in AIR !!

 

I think I need to switch back to Simiplify3D for now.

 

Would someone with this printer can print this out and tell me the result?

Thank you in advance.

ALWAYS look at the print in layer view before printing the part.

 

I'm guessing the wall got too thin for a bit.  You can either make "line width" smaller (and make wall thickness a multiple of wall line width).

 

Or alternatively try checking "print thin walls".

 

And ALWAYS look at the print in layer view before saving/printing.  You would have noticed the problem without starting the print.

HI Gr5,

 

thank you for your reply. I will definitely try with different wall thickness.

 

I went back to check the print layer of the existing setting and did not see anything wrong. Please download video.

My question is, even if the wall thickness is not a multiple of the line width, why would the Z axis jump? Is it a bug?

 

thank you so much.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
