Palette 2 is a hardware to enable a 3D printer to print multi colored objects or objects of different materials.
This a a small python script to modify the extrusion speed while doing side transitions. Side transitions offers the possibility to save filament compared to a transition tower.
Unfortunately the files produced by the web based Mosaic Canvas slicer software contains very fast flow rates while doing site transitions to change materials.
The script empowers you to change this extrusion speed. To use it download the generated file from your account on canvas3d.io, save it to your harddisk, transform it by palmod and upload the modified file to your Canvas Hub or Octoprint installation.
You can get a small help by entering:
./palmod.py -h
usage: palmod [-h] [-o OUTPUT] [-v] [-t TRANSITION_SPEED] input

positional arguments:
input input file
optional arguments:
-h, --help show this help message and exit
-o OUTPUT, --output OUTPUT
output file
-v, --verbosity increase verbosity level
-t TRANSITION_SPEED, --transition-speed TRANSITION_SPEED
sets the extrusion speed for side transitions
Here is an example for setting the side transition extrusion speed to 200 with increased verbosity and writing the result to out.mcf.gcode:
./palmod -v -t 200 -o out.mcf.gcode in.mcf.gcode

This software comes without any warranty. It currently works for me but in the future it could be possible that Mosaic Manufactoring changes the format of their generated mcf.gcode files so it could be that this script stops working. Don't blame Mosaic Manufactoring (or me) for this.
