Rabbit GRBL is a high-performance motion control firmware based on a fork of Grbl_ESP32, developed and maintained by SourceRabbit. Its goal is to provide users with a professional-grade, fast, and extremely stable CNC control solution while remaining 100% backward compatible with the original Grbl firmware for AVR processors. This ensures seamless integration with existing workflows and full compatibility with all standard G-code senders.
Designed to run on ESP32 processors, Rabbit GRBL is heavily optimized for real-time motion control. It delivers reliable, deterministic performance and is capable of generating up to 120 kHz of stable, jitter-free step pulses, making it suitable for demanding CNC, laser, and automation applications where precision and consistency are critical.
Rabbit GRBL is ideal for both advanced users and system integrators who require modern hardware capabilities without sacrificing the simplicity and ecosystem of traditional Grbl.
Rabbit GRBL combines modern ESP32 performance with proven Grbl reliability, making it a powerful and future-ready CNC motion control firmware.
