GRBL-Advanced is a GRBL-derived firmware aimed at **high performance at low cost** for CNC milling, and it is designed to run on **STM32F411RE / STM32F446RE Nucleo boards**. It is based on **GRBL v1.1 (2017)** and targets **smoother acceleration and reduced corner shock (jerk)** through **look-ahead–based acceleration control (up to 16 motion blocks)**. ![GitHub Logo](https://github.com/Schildkroet/GRBL-Advanced/raw/software/doc/en.nucleo-F4.jpg?raw=true) Image source: [https://github.com/Schildkroet/GRBL-Advanced](https://github.com/Schildkroet/GRBL-Advanced?utm_source=chatgpt.com) --- ### 1) 16-step look-ahead acceleration planning It plans speed by looking ahead at upcoming moves, which helps achieve smoother cornering and better overall acceleration/deceleration quality. ### 2) Built-in backlash compensation Backlash compensation is enabled by default, and it can be adjusted using **$140–$142 (X/Y/Z backlash in mm)**. ### 3) Drill canned cycles (G81–G83), experimental 5-axis, and partial lathe mode support Adds drill canned cycles **G81–G83Experimental rotary axis (5-axis) support** (may contain issues / includes caution notes) **Lathe mode:G33 / G76** (requires a rotary encoder) --- ## Ethernet CNC control with W5500 GRBL-Advanced can be controlled via **USB or Ethernet**, and it explicitly states that a **W5500 module is required** for Ethernet use. Default connection settings are **IP 192.168.1.20** and **port 30501**, and it recommends **Candle2** as the control interface. In other words, you can build a setup like: **“PC (or network) → W5500 (Ethernet) → STM32 GRBL controller”**, which greatly improves freedom in machine placement and cable routing. ![W5500](https://github.com/Schildkroet/GRBL-Advanced/raw/software/doc/w5500.png?raw=true) Image source: [https://github.com/Schildkroet/GRBL-Advanced](https://github.com/Schildkroet/GRBL-Advanced?utm_source=chatgpt.com) --- ## Candle2 Candle2 is a **Qt-based GRBL control GUI**. On a PC, it is used to **load, edit, save, and send G-code** to a CNC controller (e.g., GRBL/GRBL-Advanced) and to **visualize toolpaths (Visualizer)**. In practice, it’s an all-in-one application combining **sender + monitoring + visualization**. Key features include: **G-code file loading / editing / saving / sendingG-code visualization (Visualizing)Height map** feature The Candle2 release notes also state that it supports **GRBL 1.1 and GRBL-Advanced**, and that GRBL-Advanced supports not only USB but also **Ethernet (GrIP)** connections. ![image1.png](https://github.com/Schildkroet/Candle2/blob/master/Screenshots/image1.png?raw=true) Image source: [https://github.com/Schildkroet/Candle2](https://github.com/Schildkroet/Candle2?utm_source=chatgpt.com) --- ## Example: W5500 + CNC [Embedded media](https://www.youtube.com/embed/rfunxBPfJw8) Video source: --- Source: https://maker.wiznet.io/mason/projects/grbl-advanced/
