Running pronterface.py on Mac OS X Lion

Some of us have run into issues running pronterface.py on Mac OS X Lion. I believe the problem occurs when python is in 64-bit mode and wxPython in 32-bit.

I installed this version of wxPython: [superb-sea2.dl.sourceforge.net]

And run pronterface.py with this command:

arch -i386 python pronterface.py

And that seems to work! digifab confirmed that the same setup works for him. Post here if you have problems, and I'll try to follow up.

Same thing here. This is what I do:

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

Hello had massive problems trying to get this working now thanks to you I have, Just wanted to know if anyone knew hoe to write a BASH script for running "arch -i386 python pronterface.py" from a single click. I know this is probably ridiculously easy just a bit of a beginner at these thing.
Cheers

alias pronterface='/usr/bin/arch -i386 python pronterface.py'

Stick that in a file called .bash_profile in your home directory.

Oh wait, I misread that. If you want to launch it with the Finder you'd do something like:

nano launch

Then paste in the following:

#!/bin/sh
arch -i386 python /path/to/pronterface.py

Then make it executable:

chmod ugo+x launch

Can't seem to make it work, I do as above save out the file from nano launch, when I try and open it it opens in xcode, so I changed the it to a .command, now it opens in terminal but says

I'm guessing you didn't fully properly specify the path to pronterface.py

You'll want a path that looks something like:

/Users/stanleytanser/printrun/pronterface.py

Ok thanks will give it a go and see what happens, I have just relies that Pronterface on the MAC does not have the same interface as when it is running on my PC, I have lost the arrow buttons that allow you to move the print head around when nothing is printing. Is anyone else suffering from this?

Yes, I was too. You need to reinstall the 32-bit version of wxwidgets.

Could you send me the link to 32-bit wx widets for mac, cant seem to find it is it a standalone installer? Thanks

This tracks to my experience and now my pronterface with OS X Lion is pretty stable. From within Terminal, I navigate to the Printrun folder, execute the 32 bit override and start pronterface (python pronterface.py).

However, I'm limited to using Sprinter for my firmware. I got Marlin to work a couple of times early on, but now it never connects whereas Sprinter always connects.

Oh well, I'm printing.

You've solved my problems!
Thanks!!!!!

Since I just installed pronterface on my Mac so I could control two RepRaps (I usually use my linux laptop for RepRap stuff) I thought I'd throw in a little AppleScript trick too..

To make a pretty Application that looks real to MacOSX but actually just runs a script, do this:
Launch AppleScript Editor (Applications->Utilities), create a new script, and have its contents be:

do shell script "export VERSIONER_PYTHON_PREFER_32_BIT=yes; python /path/to/where/you/put/Printrun/pronterface.py"

Run it first to make sure it works, then Save As and save it as an Application.

Then, you can click on the new Application, Get Info, click the icon in the upper left, and paste whatever icon you want onto it, so it looks like a real app.

Or you can use the native OSX app Kliment now offers for Pronterface:

[koti.kapsi.fi]

It also works fine with the Mountain Lion preview.

Thanks John. I have been trying to connect to a gen6 board from Lion with pronterface (this version and the latest run from the command line). I am not able to connect but I can connect from windows prontorface (same version). Very frustrating since I really wanted to do this from my OSX box sitting on my desk and not down in my shop.

Any suggestions? I have the most recent driver installed and set speed to 38400 baud just like on windows. I just get "Connecting..." and nothing else, no timeout or anything.

regards,
Michael

I initially downloaded the binary, but couldn't figure out where to put skeinforge, so I went with the github version.

Sorry...I've got no experience with Gen 6 electronics...I'm using RAMPS 1.4 @ 250000 baud (previously 115000).

I didn't have to install any drivers on my setup although I had previously used Arduino software which comes with everything I believe.

Sounds like your ports aren't configured/chosen correctly if you're just getting "Connecting..."

Just wanted to check in and see if you had come up with anything on this? I"m just hooking up my setup too, and running into the same problem.
