open_stream_file(file=None, offset=200, collapse=False, unit_pitch=0.13)[source]#
Open stream file, convert to nm and define enclosing volume dimensions.

A valid stream-file should consist of 3 columns and start with ‘s16’ line.

  • file – path to the stream-file

  • offset – determines a margin around the printing path

  • collapse – if True, summ dwell time of consecutive instructions with identical coordinates


normalized directives in nm and s, dimensions of the enclosing volume in nm
