This is a Grbl_ESP32 CNC Development board. This is a quick and easy way to use and test CNC on the ESP32 controller.
Grbl is a great CNC firmware that has been around for nearly a decade. It was originally designed for the Arduino UNO and basic 3 axis CNC routers, but it has been ported to other CPUs and was the basis for many other CNC and 3D printer firmwares.
The firmware was written using the Arduino IDE to make it as user friendly as possible. If you have experience with Arduinos, this will not be much different. There are currently two branches of the firmware.
Memory - Currently, due to memory restrictions, you can't run all features at the same time. Bluetooth and OTA (over the air) updates both require a lot of flash memory, so you can't have both. If you want Bluetooth, you will have to upload firmware using the traditional USB method. We hope this memory issue is only temporary as we test alternate partitions of the memory.
I/O - The ESP32 is very flexible allowing you to remap the the I/O features to alternate pins. Grbl_ESP32 is also far more flexible than Arduino Grbl for assigning pins to features. But, when you make a PCB, you force specific pins to specific features. To give some flexibility there are some shared pins. The SD Card shares pins with Mist coolant, Spindle Direction and Spindle Enable. These pins were chosen because they are very rarely used in DIY CNC. Full control of a variable speed spindle is still on a dedicated pin. If you really need the SD Card and some of those features, contact me. There are many alternative ways to do that. See this wiki page for additional info on I/O.
ESP32 brings the following features to small scale CNC.
The board has the following features.
I ported Grbl_ESP32 and made this CNC controller to simplify and lower to cost of small-scale CNC. I chose to use the Arduino IDE to develop the firmware, so a beginner can configure and compile this firmware. Grbl_ESP32 will eventually allow the first sub $10 CNC controllers with native Wifi and Bluetooth.
I am the lead developer of Grbl_ESP32. All purchases will help me fund future development of this exciting project.
Everything is Open Source
A full assembled and tested base PCB.
New with Version 3.1, there is a built in SD card socket and a built in power supply (no longer modules).
