Manual Joystick controller for MPCNC

thingiverse

This is an extremely detailed guide on how to build a joystick-controlled jog dial for an MPCNC (Machining Center Personal Computer Numeric) using an Arduino Nano. The guide includes: 1. Hardware requirements: - Arduino Nano - Breadboard - Wires - Tactile switches - LEDs (red, green, blue, yellow, and white) - PLA for the case - Screws 2. Software Requirements: - Arduino IDE - Marlin Firmware 3. Steps to build the jog dial: a. Connect the Arduino Nano to your computer's USB port and upload the script "jogdial_v0.2.ino" from the Arduino IDE. b. Detach the Nano from the USB port and start wiring according to the Fritzing breadboard chart provided in the guide. c. Hook up the 4-pin connector to your lower Aux-1 pin (D0, D1, GNS, 5V). Be careful not to reverse the connections as it may damage the Arduino Nano. d. Ensure that your Marlin Firmware is set to 250000 bps and adjust line 57 in the arduino-script accordingly if you want to use a different baudrate. 4. Case Design: - The case design was created using OpenSCAD and can be optimized for better performance. 5. Operation of the jog dial: a. On power on, all five LEDs light up for a second, then the blue LED is lit up. b. Press HomeXY to home the system. Press Home Z if you have a tool-height thing attached on your Z-endstop. c. If you have set your spindleheight to 0, press reset coord button to zero XYZ. 6. Manual Driving: - Blue LED on: Using Joystick advances Toolhead in +-0.1mm increments. - Green LED on: Using Joystick advances Toolhead in +-1mm increments. - Yellow LED on: Using Joystick advances Toolhead in +-10mm increments. - Red LED on: (Red means DANGER!!!) Using Joystick advances Toolhead in +-100mm increments. Be aware not to exceed your machine limits!! 7. Safety Note: - The author is not responsible for any damage you do to your machine. Overall, this guide provides a detailed and comprehensive step-by-step process for building a joystick-controlled jog dial for an MPCNC using an Arduino Nano. It covers hardware requirements, software requirements, case design, operation of the jog dial, manual driving, and safety notes.
