Pre-Compiled xPro-V5 firmware has been fully tested and verified
The most up-to-date precompiled xPro-V5 firmware can be found here: https://github.com/Spark-Concepts/xPro-V5/tree/main/Firmware
Important compiling instructions are in the wiki
The code should be compiled using the latest Arduino IDE. Follow instructions here on how to setup ESP32 in the IDE. The choice was made to use the Arduino IDE over the ESP-IDF to make the code a little more accessible to novices trying to compile the code.
For basic instructions on using Grbl use the gnea/grbl wiki. That is the Arduino version of Grbl.
The CNC xPRO V5 firmware is based on the awesome work of BDring porting the original GRBL to an ESP32 platform. The original Grbl is an awesome project by Sungeon (Sonny) Jeon. The core engine design is virtually unchanged.
The Wifi and WebUI is based on this project.
