LEETArduinoPendant

A UCCNC Plugin to receive commands from an Arduino Nano-powered CNC Pendant Uses Solid.Arduino library to talk to Arduino Nano

1. PCB Design

• Electronics Design: https://a360.co/3NGWRTP
• https://a360.co/3NLhfDk
• https://a360.co/3JObaVh

Design notes:

• All resistors used were 10K

• Speed and Feed potentiometers are 10K Their pinout goes like this: Wiper->ground = 0%, Wiper -> +5V = 200%

• Axis and Handwheel Increment rotary switches are 4-position and their pinout goes like this:

  • Axis select pins: 1-X, 2-Y, 3-Z, 4-A, C-Common (+5V)
  • Handwheel Increment pins: 1-0.0001, 2-0.0010, 3-0.0100, 4-0.1000, C-Common (+5V)

• All function buttons such as Jog +/-, M1, M2, etc are sending +5V signals to the digital pins D2-D12 D13 digital pin is connected to a LED indicator and is used to tell the user that the Pendant is allowed to send signals to the plugin.

3. Arduino Setup

• Install the Full Firmata library onto your Arduino Nano (Or any other Ardiono that supports USB Serial Communication):

StandardFirmata sketch used for Arduino NANO is also added to the release package

• Please note that you might need to install Arduino USB Driver in order for your Arduino to work on the target computer!

4. UCCNC Setup

• Download the latest LEETArduinoPendant from the releases and extract it to your PC.
• Copy the LEETArduinoPendant.dll plugin file to the C:\UCCNC\Plugins directory!
• Copy the Solid.Arduino.dll file from the Solid.Arduino release folder to the C:\UCCNC directory.
• Please note that you might need to install Arduino USB Driver in order for your Arduino to work on the target computer!
• Launch UCCNC.exe, go to Settings->Configure Plugins, and mark the LEET Arduino Pendant plugin as Enabled and Call startup
• After everything is installed, Arduino is connected and UCCNC is running, press the "Enable" (+5v to D2-B-ENABLE ) button that will tell the plugin that the pendant is ready to send signals! D13 (LED+) will then have a continuous +3.3V signal alerting you of that!
