Flsun Super Racer Prime Line Fix

Fix the issue of the prime line being generated outside of the print bed in OrcaSlicer when using the Flsun Super Racer.

---

Overview

When slicing with OrcaSlicer for the Flsun Super Racer, the default G-code configuration may result in a prime line placed outside the printable area. This script provides a post-processing solution to adjust the prime line's location within the valid print bed, ensuring smooth operation.

This guide is specifically designed for macOS users leveraging the macOS Terminal to run the script.

Installation & Usage

Steps for Mac, commands may be slightly different on other operating systems

Step 1: Clone or Download the Script

Download the script directly from this repository:
git clone https://github.com/Krosko/flsun-prime-line-fix.git
cd flsun-prime-line-fix

Alternatively, download the post_process.py file from the repository and save it to a convenient location.

Step 2: Slice Your Model

1. Open OrcaSlicer and load your 3D model.
2. Slice the model and save the resulting .gcode file to a known location.

---

Step 3: Run the Script in Terminal

Option 1

1. Open Terminal on macOS.
2. Navigate to the folder containing the script:
   cd /path/to/folder/containing/script
3. Run the script with the following command, replacing /path/to/file/filename.gcode with the full path to your .gcode file:
   1. python3 post_process.py -f /path/to/file/filename.gcode
   2. -t /path/to/target/location/filename.gcode can be added behind the command to define the target location of the processed .gcode file
4. If successful, you will see a message like:
   File updated successfully.
Number of lines replaced: X

Run python3 post_process.py --help for informations about the -f and -t flags

Option 1

1. Add the path to python and the executable script to the Post-processing Scripts section of the OrcaSlicer

---

Step 4: Print Your Model

1. Transfer the processed .gcode file to your printer via SD card or another method.
2. Start your print and verify that the prime line is now correctly placed within the print bed.

Customization

If you'd like to modify the new prime line routine, you can edit the new_content variable in the post_process.py script. Ensure the G-code commands are compatible with the Flsun Super Racer and OrcaSlicer.
