Pronterface error - please help!

I have just set up my prusa with Pronterface on my mac. I get this error when trying to load something to print:

ImportError: /Users/Macbook/Desktop/RepRap/pronterface.app/Contents/MacOS//cStringIO.so: no appropriate 64-bit architecture (see "man python" for running in 32-bit mode)
I have no idea what i should do to resolve the problem.

Any help would be appreciated

Thanks, Simon

In the terminal window you use to open pronterface, you must first force python to be 32-bit, like so:

export VERSIONER_PYTHON_PREFER_32_BIT=yes

I have a text file with the following:

export VERSIONER_PYTHON_PREFER_32_BIT=yes
/Applications/Printrun/pronterface.py

Add ".command" to the end of that file, make it executable, and you have a double-clickable file that will run pronterface. I'm sure there are better ways of doing this, but it works for me.

I have typed that into the terminal but now an error comes up like this:

ImportError: dlopen(/Users/Macbook/Desktop/RepRap/pronterface.app/Contents/MacOS/cStringIO.so, 2): no suitable image found. Did find:
/Users/Macbook/Desktop/RepRap/pronterface.app/Contents/MacOS//cStringIO.so: no matching architecture in universal wrapper
/Users/Macbook/Desktop/RepRap/pronterface.app/Contents/MacOS/cStringIO.so: no matching architecture in universal wrapper

In a Terminal Window:

Run the export command then
Try running {path to where pronterface.app}/pronterface.app/Contents/MacOS/pronterface

Then try loading an .STL file

That works for me with the pronterface.app

Jez-a, I was getting the original error and your method fixed it for me as well. One thing to add - I had to 'cd /Applications' first so that pronterface was able to find skeinforge. When you run it from the command line like that I guess it tries to find things relative to the directory where you ran the command as opposed to the directory where pronterface is.

Hi voodoomagicman,

Glad that you were able to get pronterface working.

I just ran the following command from the terminal window, from within my user home directory:

/Applications/3DPrinting/Pronterface/pronterface.app/Contents/MacOS/pronterface

I have also changed the Settings->Options within Pronterface to point to where skeinforge is located. In the dialog box, change the "slicecommand" and "sliceoptscommand" to point to where skeinforge is installed - this might help.

Cheers
Jez_A

Hi, I used to use repsnapper for my mendel machine (actually it is someone else's). Now that I have installed the prinrun pronterface, what should I put in the 'slicecommand' and 'sliceoptscommand'?
