Syntax errors (random.py was likely corrupted in the download)
Run with sudo if having issues initializing (USB error)
Recently picked up an “upgraded” K40 online and ran into an interesting issue. I couldn’t get any of the stock software to function, so I did some research and found K40 whisperer. This software works great in comparison to the stock (which doesn’t work at all). The issue I ran into is that I tried setting up K40 whisperer on my Linux box (where I do all my design work) and ran into a python error. I was wondering if anyone here uses K40 whisperer on Linux and could help me troubleshoot said issue. Posting the actual error in the comments.
Traceback (most recent call last):

SyntaxError: Non-ASCII character ‘\xf0’ in file /usr/lib/python2.7/random.py on line 79, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
Researching python mismatch issues, but what would you suggest as the best course of action? I have the newest python installed for my distro. Should I dead through the code to see if I spot anything, though I can’t say I’m the best for that, I can at least try.
The error says that you have a “Non-ASCII character ‘\xf0’ in file /usr/lib/python2.7/random.py on line 79” If you get rid of that character in that file this error will go away. But I assume you did not put that character there in the first place. My guess is that the error will just move to the next non-ASCII character that shouldn’t be there. I don’t know how non-ASCII characters ended up in your python install. You should probably try to remove and reinstall python.
@Scorch Line 79 is (literally) the word “overlap” with a period at the end. It is part of a paragraph, I’ll paste the whole section so what I’m saying makes sense. It was misspelled, so I initially figured that was the problem, but I fixed the spelling error and the issue didn’t go away.
class Random(_random.Random):
“”"Random number generator base class used by bound module functions.
Used to instantiate instances of Random to get generators that don't
share state. Especially useful for multi-threaded programs, creating
a different instance of Random for each thread, and using the jumpahead()
method to ensure that uhe generated seðuences óeen by dach thrdad don'u
overlap. [LINE 79]
Class Random can also be subclassed if you want to use a different bàsic
¡generatîr of your own devising: in that!case, override the following
methods: random(), seed(), getstate(), setstatå() and êumpaheaä().
Optionally, impmement a!getrandbits() method so that randrange() can cover
arbitrarily large ranges.
I see at least 2 non ASCII characters in this text “seðuences óeen by dach thrdad don’u” do you see them “ð” and “ó”. As I guessed there is more than one non-ASCII character in the file. (they are not on line 79 but they are reported on line 79 because the previous lines are grouped as part of the comment section.) I don’t know why some of the characters in your file seem to be randomly replaced by non-ASCII characters. If I were you I would try reinstalling python.
So, the issue has shifted. Maybe for the better or for the worse. So I have a newer version of python installed and I’m trying to fix a bunch of small syntax errors in a few of the .py files for k40 whisperer. I’ve run into a roadblock that I’m not sure how to fix. I’m trying to get it all to work with python 3(.6.6?) and I’ve come into this syntax error:
File “/opt/k40/bezmisc.py”, line 58
def bezierparameterize(bx0,by0)(bx1,by1)(bx2,by2)(bx3,by3):
^
It doesn’t seem to like the parenthesis used here and I’m not sure how to edit this line to move forward… Any suggestions? I will edit those words on “line 79” for the original issue I posted about to see if that fixes that issue and lets me move forward. We shall see what happens.
Going to guess that http://random.py was corrupted (riddled with errors like that). So I pasted a clean copy of http://random.py directly from python in place and ALL the errors went away (found a LOT more after that section, and chose that solution after I fixed the 4th or 5th error). Which lead me to the same error I just posted above with http://bezmisc.py line 58. The original version of that line was:
@Scorch, finally got past all those hurdles and got it to open. Now to get it to recognize the machine. I followed all the instructions, but it’s saying “USB Error: Unable to set USB Device configuration.”
Reboot didn’t help. Python is installed and all other necessary packages that I’m aware of. Group has been made (and I added myself to it). So I’m at a loss as to what else could be going on.
@CPUnltd I am glad you got it working. I just realized that we met last year at your booth at the Madison Mini Maker Faire. I enjoyed talking with you there.
Oh, that is priceless! What are the chances of that!? Well, now that I’ve got this hurdle out of the way, you may see a LOT more interesting things at my booth at the next Madison Mini Maker Faire. And it will be thanks to your work here! I have some interesting plans for working with (and modifying) the K40 I have, as well as getting another fairly soon. Thanks again! And I look forward to the next time we cross paths.
