The "HE1" line of the [Z Endstop PCB for Voron v2.4 board](https://deepfriedhero.in/products/z-endstop-pcb-for-voron-v2-4) (on the LDO Kit they refer to this as the "Nozzle Probe" line) will connect to to the "STOP_2" on the Octopus Pro board. -Motor cables: Please use a LED light to ensure that the pairs of wires for each motor coil are lying next to each other in the motor cable's connector. If the two adjacent wires do not turn on the LED light when you turn the shaft of the motor then you will need to find the appropriate pair of wires and ensure that they are adjacent to each other in the JST connector. What do I mean by two adjacent wires. Well the JST connector has 4 pins. Pick a starting point, call that "PIN 1" then the next pin adjacent to it in the JST connector is "PIN 2". Place an LED across "PIN 1" and "PIN 2". Turn the stepper motor shaft to see if the LED turns on while you turning the motor;s shaft. If the LED turns on then "PIN 1" and "PIN 2" are a coil pair. Now check "PIN 3" and "PIN 4", just to ensure that the second motor coil is working properly. Place the LED across "PIN 3" and "PIN 4", does the LED turn on? Now that you have determined which pairs of motor wires make up a coil pair. Place the coil pairs as follows: PIN1 and PIN2 is a coil pair, PIN3 and PIN4 is a coil pair. +Motor cables: Please use a LED light to ensure that the pairs of wires for each motor coil are lying next to each other in the motor cable's connector.

Place the "A" Motor cable into "Motor_1" connector on the Octopus Pro board.
