CNC Joystick Pendant

This is my take on adding an joystick to jog my MPCNC. I didn't want to have a separate box for the joystick and the LCD controller, so I combined them. I also wanted some dedicated buttons, for homing and zero because going thru the menus was a pain. I used an Arduino Nano clone for that. (Make sure you use the correct driver and cable to program).

The joystick support is already in Marlin. A discussion of this and where I got all of my information from on how to set it up comes from this thread:

I included the bench mount I made for it as well. Just keep in mind the LCD cable have to remain short.

The Arduino sketch for the buttons is a derivative on the source provided by Armith (see the remix sources). I basically took out all of the original joystick handling and just kept just the button parts I needed. Pretty simple to follow.

The schematic references the Rambo 1.4 specif
