I just finished the build of my MPCNC Primo except for the wiring. I bought the Rambov1.4 board, LCD display and the complete wiring kit with end stops. I can’t find a diagram to show how all this hooks up. I only see one output each for the x & y axis on the board but I read somewhere that if you’re using end stops each stepper motor needs to be hooked up separately. Do the two display cables go to P1 & P2? There are two connectors for the z axis but only one stepper motor. Why? A diagram would really help.
