# Grbl (CNC Controller) For ESP32
|
|
|
|
|
|
|
|
### Project Overview
|
|
|
|
[](https://travis-ci.com/odaki/Grbl_Esp32)
|
|
|
|
This is a port of [Grbl](https://github.com/gnea/grbl) for the ESP32. The ESP32 is potentially a great target for Grbl for the following reasons
|
|
|
|
- **Faster** - At least 4x the step rates over Grbl
|
|
- **Lower Cost** -
|
|
- **Small footprint** -
|
|
- **More Flash and RAM** - A larger planner buffer could be used and more features could be added.
|
|
- **I/O** - It has just about the same number of pins as an Arduino UNO, the original target for Grbl
|
|
- **Peripherals** - It has more timers and advanced features than an UNO. These can also be mapped to pins more flexibly.
|
|
- **Connectivity** - Bluetooth and WiFi built in.
|
|
- **Fast Boot** - Boots almost instantly and does not need to be formally shutdown (unlike Raspberry Pi or Beagle Bone)
|
|
- **RTOS (Real Time operating System)** - Custom features can be added without affecting the performance of the motion control system.

### Using It
|
|
|
|
The code should be compiled using the latest Arduino IDE. [Follow instructions here](https://github.com/espressif/arduino-esp32) 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.
|
|
|
|
I use the ESP32 Dev Module version of the ESP32. I suggest starting with that if you don't have hardware yet.
|
|
|
|
For basic instructions on using Grbl use the [gnea/grbl wiki](https://github.com/gnea/grbl/wiki). That is the Arduino version of Grbl, so keep that in mind regarding hardware setup. If you have questions ask via the GitHub issue system for this project.

### Credits
|
|
|
|
The original [Grbl](https://github.com/gnea/grbl) is an awesome project by Sungeon (Sonny) Jeon. I have known him for many years and he is always very helpful. I have used Grbl on many projects. I only ported because of the limitation of the processors it was designed for. The core engine design is virtually unchanged.
