ESP32-cnc

Wirebender

This project will build a wire bender

3D designs are shared in STL format. The 3D model is available as a Fusion 360 project Wire bender

inspiration can be found in

• LiveWire
• Precise Wire Bending Machine
• DIY-wire-bender

The aim of the project is to combine best of both world and come up with a precise 3D wire bender.

ESP32-Grbl Controller

This part of the project is based on the project or bdring's Grbl_ESP32_MPCNC_Controller with addition of 2 servo axis, which will be used in our wire bending project. This ReadMe file is mostly a copy of the original project. As we go we will adapt the content.

This is a CNC controller specially designed to address the needs of the MPCNC (Mostly Printed CNC) CNC Router. Secondary X and Y axises can be used as servo outputs. This will be usefull for the wirebender project.
