use cura from windows cmd

[geosfi 0]

Hi im George this is my first post here. I use cura with all my printers and now i have a msc thesis assignment and i want to control cura through windows terminal. I can open a stl file, i used cura -s and sliced it. Finally i want to use cura -r in order to open the print interface and print the object. The problem is that i get

AttributeError module object has no attibute startPrintInterface

and it gives me errors in some lines in the cura.py and runpy.py files. Do you know how i can make it works?

Thanks!

This is no longer possible from the commandline. (This was an internally used interface which has changed)

You can use prontoface to send the .gcode file to your printer.

Ok. I can send the command from windows cmd to slice the file. I have done it and create a gcode file. And then send the command to open cura the gcode file. This is almost there i believe is good enough. It would be nicer if i could get the print info (estimated time, weight of object and cost) do they stored somewher? I cant find them in gcode file.somewhere else maybe where i can have access? I want to find them and send them through a web service.

Hi,

How to generate gcode file from STL file using CMD prompt in Windows.

Installed with CuraEngine-14.05.3. Want to convert STL file to gcode file and print from CMD prompt.

Please tell me the exact command.

Thanks,

Hi,

While running CuraEngine -s "C:\path\to\STL File\" I'm getting the below output:-

Hi geosfi,

Can you please let us know what exact command you have given to produce a gcode file from CMD prompt.

I don't have .ini file. I just use to give CuraEngine -s "C:\path\to\STL File\"

Though it is producing .gcode file the contents are not the expected stuffs.

I get the out put as below:

For Cura 15.04.4 (and probably 14.x.x.), Enter: CuraEngine.exe -help

For Cura 2.1.2, Enter: CuraEngine.exe help

Those will show you the command line parameters for both versions of the CuraEngine.exe program.

Hi,

Tried passing all kind of arguments with all possible ways but every time gcode is produced with unexpected contents. They seems to be of around 15 lines of info without gcode complete contents.

Without -o C:\Path\to\fileName.gcode option the output is coming as below:

While running the CuraEngine -s "C:\Path\to\file.stl" I'm getting the output as below:

Kindly let us know the exact command.

I do not have .ini file.

I don't know why you're doing: CuraEngine -s "C:\Path\to\file.stl"

That's not what the -s switch does.

Following the CuraEngine usage help works fine for me.

Hi,

It is generating the .gcode file but contents are not expected.

We get the below error message:

-------------------------------------------------------------------------------------

Default config 'default.cfg' not used

Config(part1.ini): Line 1: No key value pair found

Failed to read config 'part1.ini'

Failed to open part1.gcode for output.

--------------------------------------------------------------------------------------

It is generating well from UI.

Do we need any licence or rights to run it from command prompt?

We do not get .ini file any where.

If no licence is required then can you please share the exact command using which we can generate a .gcode file

Please guide me what ideally I should be doing.

Thanks & Regards,

Debakanta

[DaHai8 74]

Well, I don't know what command line you are using that results in your 'Config(part1.ini): Line 1:No key value pair found" error. I don't know what part1.ini file is from your set up.

I also didn't know how to do any of this until just over a few hours ago when I saw your post and decided to see if I could figure it out for myself. So I'm no expert. But I did get it working to a degree.

In addition, I'm using Cura 15.04.4 which is newer than yours and so yours may contain bugs that are hampering your progress.

All that said, from following the -'help' switch output from CuraEngine, the most basic slicing command for .stl in and .gcode out would be:

 

CuraEngine.exe -o c:\path\to\output.gcode c:\path\to\input.stl

 

If you wish to supply an .ini file for your printer's setting, you need to: File / Save Profile in the Cura GUI and then use that .ini file on the command line in Cura:

 

CuraEngine.exe -c c:\path\to\profile.ini -o c:\path\to\output.gcode c:\path\to\input.stl

 

However, I have been unable to get the CuraEngine to read the .ini file. It always returns this error:

Line zd: No key value pair found

Not sure if your older version of Cura will work on reading the .ini or not.

Hi,

I'm able to generate .gcode file using below command

CuraEngine -c "C:\path\to\preferences.ini" -o "C:\path\to\test1.gcode" "C:\path\to\\snowManAll.stl"

It is failing to load if I pass .obj or .amf file instead of .stl files

Need your guidance in this concern.

Thanks & Regards,

Debakanta

Hi George,

Try below command from CMD prompt

CuraEngine -c "C:\path\to\preferences.ini" -o "C:\path\to\test1.gcode" "C:\path\to\\snowManAll.stl"

Thanks,

Can you please suggest me how to give print command option to a gcode file.
