If you need a solution for you CNC project, you might want to look into the Grbl_Esp32 (for ESP32 specifically) or grbl (for Arduino in general) Libraries.īut if you are looking for an easy way to setup and control one or more stepper motors independently and adding limit switches and rotary encoders to control them, then this project here might be just what you are looking for. It does not support Gerber commands (GRBL) in general or fully synchronized multi axis movements (it can move multiple axis at the same time though since it generates all step signals for all connected stepper drivers asynchronous). This library is not ideal if you are looking for a solution to control your CNC Router. Once the ESP Stepper Motor Server has been uploaded to the ESP module, all further configuration and controlling can be done vie the web UI without the need to code another line in the Arduino or PlatformIO IDE. Since the ESP-32 modules contain a WIFI module they are perfectly suited for web-controlled stepper server and since they have enough memory and processing power they are ideal as low cost, low energy consumption standalone server component, that allows configuration and controlling of one to many stepper motor drivers with limit-switches and outputs (e.g. The core part that controls the stepper motor drivers is now based on a modified version of FlexyStepper, called ESP-FlexyStepper. Soon this library became much more than a modfied version of FlexyStepper but turned into a stand-alone application to turn a regular ESP32 module into a stepper motor control server. While the FlexyStepper Library is a general Arduino compatible library this fork had a focus on the ESP32 modules from Espressif. This library started as a fork for the FlexyStepper library.

Configuation via the web user interface.

Setting up your ESP-StepperMotor-Server.

Turn your ESP32 into a standalone stepper motor control server with easy to use webinterface.Ĭonnect one ore more stepper controllers with step and direction input, and optionally some limit-switches to the IO-pins of your ESP module and control the stepper motor via an easy to use web interface, via REST API or via a serial control interface.
