Best slicer decisions

Top Recommended Slicers

PrusaSlicer (Best Overall for Voron 2.4)

Optimized for CoreXY kinematics
Advanced tuning options for pressure advance, input shaping, and acceleration
Supports conditional G-code for RepRap Firmware macros

SuperSlicer (PrusaSlicer Fork with Extra Features)

Includes advanced tuning options specifically for Voron printers
Built-in Voron print profiles optimized for speed and quality
Best for users who want fine-tuned settings for flow rate, acceleration, and pressure advance

Cura (What You're Already Using)

Works with RepRap Firmware, though less optimized for CoreXY
Requires manual tuning for acceleration and jerk settings
Good if you prefer the Cura UI and workflow

Honorable Mention: IdeaMaker

User-friendly interface and easy profile setup
Works well with Voron printers but requires post-processing scripts for RepRap Firmware

Final Recommendation

Since you’re already using Cura, it might be worth trying PrusaSlicer or SuperSlicer, as they offer better support for Voron 2.4’s CoreXY movement and RepRap Firmware compatibility. If you find SuperSlicer’s new Graph Edition confusing, you can stick with PrusaSlicer or download an older version of SuperSlicer (pre-Graph Edition).
