ESP32 software to control a router table using stepper motors.
The main objective of this project is to develop software for an ESP32 router table control that is based on the Table Router Shield developed by Timo's Werkstatt, see https://blog.altholtmann.com/untertischfraese-tischkreissaege-kombination/, but offers more features, e.g., those of the router table control published by Offys Werkstatt, see https://www.youtube.com/watch?v=YSfgVo2PLS4&t=595s, and develoed by Frohnix Bastelbude, see https://www.youtube.com/watch?v=eAtvLXTf3fg. After reviewing the existing code developed by Timo's Werkstatt and Frohnix Bastelbude, I came to the conlcusion that they are not adequate for my needs. For example, the code from Frohnix Bastelbude includess several other projects which makes the code quite complex. On the other hand, the code of Timo's Werkstatt does not include the features I would like to have and not the hardware I have available. However, another important argument for my own code is, of course, that I like to learn how to program ESP32... :-)
Altough my main target is to develop software for the Table Router Shiels of Timo's Werkstatt, it should work with the majority of ESP32 boards, since Timo's is mainly a breakout board only.
User Features:
- Manual movement of spindle using handwheel
- Move to null, park position, and target position defined using the handwheel
- Automatic tool length measurement and definition of null position
- User-defined limitation of upper/lower spindle limits based on park position and target position
- Definition of feed speed and moving to the target position using this feed speed (to immerse cutter into workpiece
Properties:
- Table Router Shield of Timo's Werkstatt, but allow easy migration to other ESP32 boards
- OLED I2C Display
- Use only one input for both, lower and upper endstop
- ESP32
