Save issue

[billout25]

Dear All, I have an issue, when I want to save a big model, Cura don't want save the Gcode, I need to change the resolution of modele with less layer or etc... to decrease the size of the file (approx less 150'000 Mo). It's possible to increase this value? Thanks Billout25

same issue for me, can't save the gcode of a high def model in 0.02

Most likely this is an out-of-memory issue, is this on Windows or MacOS?

Hi, it's on Windows 7, 64 config: Intel core i7 - 2960XM CPU @ 2.70GHz + 16 Go of RAM virtual memory = 16Go Thanks

windows 7, 64 core i7-4770k @ 3.5 ghz + 32 ram

memory never used more than 15 %

Cura is a 32bit application, so it can only fully use 3GB of ram. Can you see how much ram "python.exe" is using when this failure happens?

I'm having this issue right now (win7 x64 24GB ram, Cura 14.09 and 14.07 ) -- Python.exe is using up 979,228Kb with a peak working set size of 1,196,944K and a commit size of 982,664K

Slicing completes, but save gcode does not work.

So it's not the 3GB limit, but possibly some other resource.

It does seem to be a memory exception of some sort within python:

Same model & same profile / settings work in 14.05RC4, so it's something since then.

Hi, My "python.exe" has finish the calculation at 410 000 K. Cura propose 55 hours and 55 meter of filament. But when I want to save the model at Gcode, Cura doesn't execute the saving (SD or HD). No error message I use Cura 14.07.1 RC1. Thanks

[daid]

I looked into this a while back, and the problem is in getting big chuncks of memory. I changed the code so it uses smaller chunks, which seems to work around this problem. The 14.09.1-RC1 has this fixed as far as I know right now: http://software.ultimaker.com/Cura_closed_beta/

I think I have the same problem. Cura does not execute saving Gcode. There is no error message. When I reboot my Mac, I can save, but once once. I have 16GB of RAM, looks like 9.5GB is in use. The Cura file I am trying to save is not large ~500KB (as a gcode file)
