G-Code Flow and Temperature Controller - Slicer Post processor

A free and open-source post-processing script for OrcaSlicer to simplify 3D printing.

This script dynamically adjusts nozzle temperature and print speed (flow rate) to significantly improve print quality and reduce print time, all while simplifying slicer settings. By optimizing these parameters, it makes 3D printing more accessible and less complex.

How Does It Work?
Filament gradually absorbs heat as it travels through the hotend, requiring extrusion at an optimal final temperature. This script calculates the average flow rate every second and dynamically adjusts the nozzle temperature accordingly. It also modifies print speed in the G-code to match the ideal flow rate, considering layer height and line width.

Why This Script?
Inspired by my personal approach and developed with basic Delphi programming skills, this is a proof of concept demonstrating the potential of integrating such features into slicer software. Doing so could unlock even greater efficiency and advanced capabilities for 3D printing.

What’s Next?
I now rely on this script for all my prints, even with my old Klipper-based printer and low-cost filament. I keep 90% of my slicer settings unchanged, proving this method’s reliability and flexibility. I believe this approach—or something similar—could shape the future of 3D printing and make it truly accessible to everyone.
