Cura hangs when slicing a long print

Recommended Posts

Posted · Cura hangs when slicing a long print

Trying to slice for some lengthy prints and can't get Cura to complete. Progress bar hangs around 70% and task manager shows that curaengine.exe and Cura have both stopped using any CPU. Have left it to sit for a few hours a couple of times now and it hasn't finished slicing.

STL file is relatively small in data size (5mb) but fills the build volume, so the sliced job is going to be around 50 or 60 hours I expect.. .

Using Cura 14.07, Windows 7 64bit. No plugins. Has anyone else had this problem before, and if so, what was necessary to get the slicing to complete?

For some reason, changing "Cut off object bottom" from 0 to 0.5 has enabled the slicing to complete, even though my print was only 180mm tall...

Try reducing the poly count. High-res mesh are longer and more complexe to slice. Also if you have options to combine everything they also add complexe checks. I had cases that the slicing would not even start and simply reduction poly count using meshlab was enought to let it process the objects.

After spending more time trying to slice very long prints, it seems that my previous "fix" was incorrect.

What seems to be happening is that after successfully slicing 50ish hours of printing a few times, cura stops being able to finish slicing that job again until cura is closed and restarted.

Odd. Can you send me your 3D model and exact settings used to d.braam@ultimaker.com

(I keep the model confidential and only use it to diagnose the bug)

Note that I've never had a processing of a model take more then 10 minutes. But my laptop is pretty fast.

I have the very same problem. When I rescale the object to 80%, Cura finishes the slicing and gives a print job of 47h, but I just want the 100% scale which is 98x125x119mm (WxHxD)

I tried the solution below, but it didn't change anything, except that my STl-file became 16MB instead of the 180MB before.

The engine log shows the following. the step that freezes isn't shown in the log.

Digging up old topics to reply in isn't really the best way to get your problems solved. Especially if there are 2 other topics about the problem already.

As I said in the other topics, if slicing stops, first check out the latest beta to see if that solves it:

Thanks Daid,

I just found that topic too. I'm sorry for replying to an "old" topic, but I couldn't find the other ones and thought it would be better to reply to an existing topic than to start a new one.

That been said, your solution indeed solved my problem for a 92h print.

Thanks again.
