Bulldozer Post Processing Script Malfunction

[3dprntz 4]

I have a script that I edited and thought it would work for the postprocessing plugin. However, when I check the g-code, it does not appear to have done anything. The older script worked before and I'm not sure if it may be too old for the newer version of Cura. I've pasted the script below:

 

# Cura PostProcessingPlugin

# Author:   3DPRNTZ

## Description:  !!! Use at your own risk !!!

##               This plugin creates gcode that can seriously damage your printer.

##               Inserts code to push the print out of the printer, and restart the print of a new object.

##               Can be used to automate production process of multiple objects. Never use unattended!

##               The model must be centered horizontally and placed in the front 2/3 of the build plate.

##               Tested with Ultimaker 3. And seriously, use at your own risk, this can break your printer.
