Problem opening gcode file

jetrock · August 19, 2017, 9:20am

I’ve managed to get a decent calibration on my non standard frame, finally.
Just before I had to leave the workshop this morning, I thought I’d have a go at cutting a gcode file, so I used the ‘Open File’ button. GC crashed, and it wasn’t a one-off. The crash message is here:

Apologies for the formatting, but the last line is probably the important one. I haven’t had time to look at the code, but I can’t see anything like this on the forum. Any ideas?

blurfl · August 19, 2017, 3:16pm

Is this the first time you’ve used the file load function, or is this behavior new to v0.85? It looks like you’re on a Linux system, yes?
I wonder whether it is a file permission problem. Looking in GroundControl.ini, look for a line like:
openfile = /full/path/to/a/file.nc
What is the path and file GC is trying to open? Can you open that with a text editor?
Try putting an .nc file in the root of your home directory and editing that line to point to it. Did that make a difference?

jetrock · August 19, 2017, 3:55pm

Yes, this is the first time I tried to open a file. Yes, I’m on a Linux system. I’m running with root privileges so I can access the USB port without mucking about, so I doubt it’s a permission problem.
I did try changing the path in a menu somewhere to one that exists, but not in the ini file.
I’ll also put a .nc file in that directory, I suspect that’s the problem, but I didn’t know the file extensions GC was looking for…
I’ll try this out tomorrow morning. Thanks for your help.

Gero · August 19, 2017, 5:21pm

Adding my user to the ‘dialout’ group worked on 3 different distros with me.
>> sudo usermod -a -G dialout username <<

https://www.arduino.cc/en/Guide/Linux (bottom of page)

mooselake · August 19, 2017, 5:29pm

Bad idea. Change the port permissions instead.

blurfl · August 19, 2017, 5:37pm

@Gero , @mooselake, looking in main.py, it wants a key ‘openFile’. Looking in groundcontrol.ini on my system in OS X, the key is ‘openfile’. What do you see for this key? Could this be a case-sensitivity issue?

Gero · August 19, 2017, 5:51pm

@blurfl ->openfile = /home/whoareyou/Maslow/test bar/Sled.nc
Linux is at all cost case sensitive
Sort the permission issue with the user and report back, would be my approach.

Edit One: In a teminal, >pip list< will spit the version of python modules installed.
If you don’t mind for comparing?

jetrock · August 20, 2017, 8:56am

Yes, that was the mucking about I mentioned. I’m allergic to these little bits of stuff. I may sort it sometime in the future. Running with root privs (sudo) isn’t much of a problem with this machine as it’s not really attached to the internet and the machines in the workshop seem to die every year or so, so everything is backed up., It’s a burner machine.

jetrock · August 20, 2017, 8:58am

I checked the .ini file and it was pointing no-where, so I made it point to my work directory and created a file there called abc.nc. GC still crashed on open. I changed the .ini file to point to abs.nc and tried again and it crashed again.

Looking at the last line

File “/usr/lib/python2.7/dist-packages/kivy/factory.py”, line 119, in getattr raise FactoryException(‘Unknown class <%s>’ % name) kivy.factory.FactoryException: Unknown class

This looks to me like a class is mising in the version of something (kivy?) that I am running.

blurfl · August 20, 2017, 12:00pm

Could you post the output this provides?

jbnimble · August 20, 2017, 5:33pm

I’ve been running Ground Control in Linux for a while now, and after doing the following commands to the user I run with it worked fine.

Like Gero said I had to add to the “dialout” and “input” groups:

sudo usermod -a -G input username

If this does not work, then my suggestion would be to do what the other folks suggested and create a user that is not root, and run as that user (adding them to the above groups).

I was going to point you to the Wiki for the Linux page, but it looks like the usermod commands in the wiki were removed, a pity.

I’ve got some other things to do at the moment, so haven’t manged to look at this.

blurfl · August 21, 2017, 3:29pm

I’m hoping one of the folks that run under Linux regularly will spot something in that pip list. All I see is kivy v1.80, where the current version is v1.10.0. I don’t know if that’s related, though.
Another thing to try would be to open the Settings and edit the ‘Open file’ setting with the full path to an .nc file. Or edit the groundcontrol.ini file in the same way, before running GC. That would bypass the kivy code for the file selection routines, might provide a data point about the issue.

jbnimble · August 21, 2017, 4:41pm

I use Python for other things so I have a bunch of different packages than the above list, but I trimmed down the list to what had different versions from mine:

$ pip list --format=columns

blurfl · August 21, 2017, 5:07pm

The Kivy(1.8.0) was released in 2014. I think I’d try upgrading that first.

jbnimble · August 21, 2017, 5:29pm

Another thing that I do in Linux (because I have Python 2 and 3 installed) is start the app like this:

$ python2.7 main.py

Which forces it to use Python 2 vs 3.

I’ve fixed this problem by installing Kivy 1.10 from source.
Thanks for all the help.
