Some general errors, and question about commands.

[DdraigX]

So I was able to get this installed/working.

When I went to do my test print it worked perfectly although it did throw an error.

./octocmd print CE3_usb_isolator2_only_data.gcode
Could not find openscad
Could not find cura

  File "/usr/lib/python2.7/genericpath.py", line 62, in getmtime
    return os.stat(filename).st_mtime
OSError: [Errno 2] No such file or directory: 'CE3_usb_isolator2_only_data.gcode'

My subsequent question , is there a way to cancel a print or pause a print from command line?

If not (I don't know python very well) could someone help me figure out where to insert the commands into the code?
