Neoπ Wireless CNC Controller (3-axis)

We chose the CNC controller made by Saheen Palayi that runs on with an ESP32 called the Neoπ. this is the same board used in Pico project by Rahul S Rajan. It is more than enough for us to run our little Zund, but needed an extra axis which can be added on later.

The board runs on ESP32 and configured with DRV8825 with micro stepping enabled. also have extra pins to run spindle and atc

This is a high performance wireless CNC controller for the same price as a Uno Shield now a days.

Firmware

the board actually support GRBL very well but we decided to go with Custom firmware to get move in freedom without any limitation. we will have more control on our own firmware because we can modify them anytime anyway
