PrusaSlicer M73 to M117 converter

Converts Prusa M73 .gcode commands to Marlin M117. M73 command's purpose is to show remaining time on Prusa3D printers.
Text output is optimised for Ender 3 default 128*64 screen. Tested with plain Python 3.10 and Marlin 2.0.

Note:
M73 command is inserted to gcode by PrusaSlicer itself. My script only replaces this command to Marlin-suitable M117. If you need M73 in your gcode, you have to follow only step 0 of "Installation".

Installation

0. If insertion of M73 commands not enabled yet: tick the Printer settings -> General -> Supports remaining time. After enabling it you will get gcode with M73 commands.

1. Install Python and remember the installation directory ([python directory])

2. Copy time_converter.py to PrusaSlicer installation folder (to store it safely with slicer itself) or to any other folder ([script directory])

3. Configure the PrusaSlicer: go to Print settings > Output options > Post-processing scripts and add line: "[python directory]/python.exe" "[script directory]/script.py";
