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.

Features

• ESP32 Microcontroller:
  • Very Fast: Dual core 32 bit, 240 MHz
  • Large Flash Memory
  • Wifi:
  • Bluetooth:
• Grbl_ESP32 Firmware:
  • Compatible with most existing Grbl gcode sender software.
  • Web User Interface
  • Multiple Interfaces
    • USB Serial:
    • Web User Interface:
    • Telnet:
    • Bluetooth:
    • SD Card:
• (5) Stepper Motor Drivers: On for each motor in the MPCNC design. Motors are ganging in firmware and have an auto squaring feature executed during homing.
• Limit Switch Connectors:
• Control Pins:
• Spindle Control:
• Fan Power:
• Micro SD card:
• X,Y,Z axis with double motor drivers for X and Y axis drive. These double axis can be disabled and converted to servo axis.
