Status says prints finished, but print is only 80% complete???

Recommended Posts

First time posting after buying my Ultimaker and in need of some help.

First, if there is already a thread on this my apologies as I could not find it. There are a lot of posts about incomplete prints but I couldn't find any where the printer acknowledges the print as being complete when it's not.

I'm running an Ultimaker 2 which I've had for about 2 months and the only modifications I've made are installing the Olsonn Block (which then lead to replacing the thermocouple....). This print was my first large print utilizing almost the entire Z axis. I have the print settings down to a slow print in hopes of achieving high detail. The total estimated print time was about 17hrs. Printer settings are default (have not turned up temp or adjusted % flow) and I'll attach the slicer settings from Cura at the bottom. material was PLA.

The problem I had, and this is the second time I've run into this, is that the printer simply stops printing before the print is complete. the hot end returns to home and the Ultimaker 2 proudly displays "print finshed you can remove the print". The quality of what is printed is excellent. The last layer shows no signs of errors in any way.

I don't have much experience in Gcode but I did review the code briefly in Repetier and can at least confirm that no lines were lost in the saving process (I've seen other people suggest similar problems may have been caused by removing the SD card to quickly).

I have 2 question for the community. First, has anyone else experienced this and do you have a diagnosis? Second, can someone advise me on editing the G-code so that I can attempt to resume the print where it left off?

My thoughts at first too, but I checked the Gcode and all 2400 layers were present.

I went to do another print just now and discovered that the nozzle was clogged.  Maybe it is possible that the printer went through the motions of completing the print but no material was extruded for the last 500 layers or so.  I would think this would cause an error way before it could run through all 500 layers though, either an overheating error or something.  Plus the nozzle and the print looked in good condition when I found the partially completed print.

I ended up breaking the print into 2 small parts which I'll join later.

I am brand new to all of this and just want to echo the same problem.  I've tried 3 different files that were STL files from thingiverse, they look good in Cura, but stop short and printer says that it's complete.  Your suggestion of halving the print is something I'm not sure how to do yet, but will have to look into.   Thanks for starting this thread, perhaps others will encounter and know of a fix. Also, I want to add that this very much doesn't appear to be an extrusion issue. The print is coming out perfectly fine and can start a new print right after with no problems or signs of any clogging. I've watched it hit this point so I know it just thinks it finished instead of going through the motions with no extrusion for the last layers.
