Cura outputs incomplete G-code

[zumfab 3]

After trying to deal with the problem described here (http://umforum.ultimaker.com/index.php?/topic/9478-umo-bed-does-not-lower-every-time-after-print/) I noticed the problem might be something different completely. Upon opening the G-code file of the troublesome print, I noticed the 'footer' found in other files was missing.

Weird thing is that it is semi-random, but not completely. Whenever I delete the G-code file and rewrite it, the same incomplete file appears. This, to me, suggests that there is some kind of generation issue. One way to 'fix' it seems to be to move the object over the build plate and rewrite. Sometimes another partial G-code appears, but sometimes it does what it is supposed to do. It happens quite regularly though, and can be quite annoying, especially because it limits the control I have over the printing process.

Is this a known issue? Cura seems to work fine when it works, it just stops short of a full file sometimes. Please note that this is happening under Cura 14.07. I just installed Cura 15.02.1 to see whether that changes anything.

Could you be removing the SD card too soon? Before everything is written? Or maybe it is a defective SD card?

It sounds like you need to inspect the file on the SD card after saving it.

It is neither of those, because I make sure to write the file to the hard drive first. The fact that Cura writes the same incomplete file twice confirms this idea, as a troublesome hard drive would not be expected to fail in the same consistent manner. Not only that, but you would also expect other obvious problems.

I have started inspecting every file I print, but I would rather solve the problem than mitigate it. As I did not get to printing today, I cannot say whether the new version does the same.

The ball is probably in my court now, but if anyone has any other ideas on what might cause this they are welcome

Have you checked the output log of Cura?

I finally remembered to save two logs from different parts. At first I though it had to do with print length or plugins, but neither seem to be the case.

[zumfab 3]

Today I have had to shuffle a part around the build plate six times before Cura would finally output complete code. I am at a total loss what causes this. Different versions of Cura display the same behaviour.

Any ideas?

 

[zumfab 3]

Currently I am attempting to print something that covers most of the build plate. Due to this error, getting a proper G-code output is proving to be impossible.

I can hardly imagine being the only one with this problem. I uninstalled all Cura versions and reinstalled the latest version, tried saving to different locations and a couple of other tricks, but the problem persists. This is really interfering with day to day printing.

Can anyone see anything in the logs? Does anyone have any other suggestions on what to try? Am I overlooking something basic?

 

[nallath 1,124]

I don't see anything weird in the logs. This is very strange...

 

[MORA 0]

Just to add some points to this not being an isolated case.

I had this happen to me today with cura 15.04

While writing 5mb gcode, cura stopped after 4.5mb, and not at a layer change or even a line change.

Didnt realise it till the printer was 10hours in, so had to do some emergency surgery to finish the print by slicing the file again, and removing the already printed gcode.
