WowFileTools

Unofficial tools to help other users of the Sparkmaker 3d printer.

• estimate_print_time.py: estimates printing time of the wow file. (Sum of layer print time and platform motion time, when speed is defined). As far I have tested, it seems to underestimate the time a little (maybe 5%? Please send me some data if you could measure precisely the difference).

• view_wow.py: displays a wow file as voxels in 3d. Warning: needs a lot of RAM and maybe a good graphics card...

• write_fake_file_for_curing.py for generating a print.wow file that acts as a curing lamp. Probably you don't need to use that script as there is already a generated file in the "CurerSlice" folder. See the readme in that folder for details

  

USAGE

python estimate_print_time.py path/to/file.wow python view_wow.py path/to/file.wow

On some platforms, e.g. ubuntu, you must call python3 instead of python, as, for the time being, the name "python" is still reserved for python 2.

DEPENDENCIES

• you need Python >=3.6 to run the scripts. (3.5 could work, didn't check.)
• estimate_print_time.py does not have extra dependencies
• view_wow.py uses pyqtgraph and numpy. Both can be installed through pip. Please note that pyqtgraph requires qt wrappers: either pyqt4/5 or pyside. Also, those wrappers must be properly setup to support OpenGL 3D graphics.

PLATFORM-SPECIFIC INSTRUCTIONS

(not really tested, please tell me if I forgot something.)

• on Windows, this boils down to:

  • download and install latest python 3.6 release from https://www.python.org/downloads/, add to PATH as proposed by the installer
  • spawn a terminal (e.g. Win+R "cmd")
  • python -m pip install numpy pyqtgraph pyopengl
  • cd folder\where\you\have\downloaded\the\scripts
  • python estimate_print_time.py path\to\file.wow

• on Ubuntu (>=16.04), should be:

  • spawn a terminal (e.g. Ctrl+Alt+T)
  • sudo apt install python3 python3-pyqt5 python3-pyqt5.qtopengl
  • sudo -H python3 -m pip install pyqtgraph numpy
  • cd folder/where/you/have/downloaded/the/scripts
  • python3 estimate_print_time.py path/to/file.wow

• on Mac OSX:

  • I have no idea.
