CNC Joystick Pendant

thingiverse

This is my take on adding a joystick to jog my MPCNC. I wanted to avoid having a separate box for the joystick and the LCD controller, so I combined them. I also needed dedicated buttons for homing and zero because going through the menus was a pain. I used an Arduino Nano clone for this purpose. Make sure you use the correct driver and cable to program it. The joystick support is already available in Marlin. A discussion of this and where I got my information from on how to set it up can be found in this thread: https://forum.v1engineering.com/t/joystick-managed-by-marlin/10863?u=dseebauer I included the bench mount I made for it as well, but keep in mind that the LCD cable must remain short. The Arduino sketch for the buttons is a derivative of the source provided by Armith. I basically took out all of the original joystick handling and just kept the button parts I needed. It's pretty simple to follow. The schematic references the Rambo 1.4 specifically, which is what I have. The link below has additional information for other controllers: https://shop.v1engineering.com/collections/parts/products/full-graphic-smart-controller-big I started writing the assembly instructions a while ago but got distracted. I included what I have, but it was mostly from memory after the fact. Sorry if it is inaccurate.
