pstoedit error

[Betibeteka Beranduetxea]

Hi all, first post here.

I'm trying to use dxf2gcode  to make airfoil sanding templates.

When I try to open the attached pdf, get this error:

tatel@tiki3:~$ dxf2gcode.py Descargas/DLG/planos/mimi/PlantillaMiMi50_tip.pdf
unknown option -mm
pstoedit: version 3.62 / DLL interface 108 (built: Sep  8 2014 - release build - g++ 4.9.1 - 64-bit) : Copyright (C) 1993 - 2013 Wolfgang Glunz
Could not open file /tmp/dxf2gcode_temp.dxf for input
Traceback (most recent call last):
  File "/usr/bin/dxf2gcode.py", line 1140, in <module>
    window.load()
  File "/usr/bin/dxf2gcode.py", line 788, in load
    subprocess.check_output()
  File "/usr/lib/python2.7/subprocess.py", line 566, in check_output
    process = Popen(stdout=PIPE, *popenargs, **kwargs)
TypeError: __init__() takes at least 2 arguments (2 given)

I think this is pstoedet complaining about -mm option, however, i can open the file with

tatel@tiki3:~$ pstoedit Descargas/DLG/planos/mimi/PlantillaMiMi50_tip.pdf Descargas/DLG/planos/mimi/PlantillaMiMi50_tip.dxf -f dxf:-mm -dt

then dxf2gcode is able to open the resulting dxf without complains

Cheers,

Roman

Hi, did you find a dxf in the folder /tmp/dxf2gcode_temp.dxf .

Which system do you use, Linux?

Regards Christian

 Yes, I'm on Linux - Debian Jessie. No dxf in /tmp directory.

dxf2gcode is working with other files, however.

Also, on some other files, I'm getting warnings about "Short elements, skipped geometries" but I don't think there are any lengths <0.001 mm on that file. I even tried setting tolerances to 0.000001. It could be that path is not closed on trailing edge, however dxf2gcode works without warning on other files obtained following the very same process.  See attachment. 

But, at the end of the day, it turns out that using dxf2gcode to do this work is not necessary. It is enough to get the original .dat file, it contains the path coordinates, and these can be multiplied into .ngc file by a #<chord> value so any template size can be cut. It could be useful for anybody triyng to cut parts, having only a .pdf drawing, which is not unusual.

Cheers,

Roman
