start the simulation with ./parse_clean xyz, where 'xyz' can be anything to name the created files.
in the end you will get 3 pictures.
swan-reference-xyz.png how it should looks like.
swan-current-xyz.png how it will looks now.
swan-diff-xyz.png is the difference.
This 3 pictures show only the X-axis.
you will get also a forth file. pp-xyz.asc. you can open this file for example with meshlab and you can see that current model in 3d.
If you want to use your own gcode, please do the following:
Create a normal gcode. Delete any M116 (temp waitings). Maybe you want also deleting comments.
Then add M114 for every x line.
I do this with the swan-test.gcode:
sed '1~2 s/$/\nM114/g' < swan.gcode > swan-test.gcode
