Revision as of 21:27, 31 March 2021

Overview

The Stepper Duonext is a dual stepper motor controller combining a touch screen Nextion display with and Arduino microcontroller.

This is an excellent unit for controlling stepper motors where human-machine interaction is involved. Nextion displays uses a really intuitive software to build your own application.

Note this unit does not support G code and Gerbl. This product focuses mainly on human interface via the touch screen display.

Touch screen display and motor drivers are sold separately.

Programming Overview

Nextion Display

The display application is build using the Nextion software. If you are new to this this is something worth learning as the potential is great.

The Nextion file is loaded on the display using SD card. This is straight forward.

Arduino

Edit your own sketch and upload it directly to the Duonext using the USB connection.

Motors - Motors are easily programmed using the StepperUNO library. Feel free to download it and look at the examples.

Interaction with Nextion - For this we recommend the NeoNextion library from this Github page.
