Wire List Z motor 1 Z motor 2 Extruder 1 Extruder 2 Y motor X motor Heater 1 Heater 2 Thermistor 1 Thermistor 2 X endstop Y endstop Z Proximity sensor

Hot End Fan 2 wires 12 Volt powered, needs to connect to the +12/GND connector on the RAMPS board This is not supplied with the kit I would think about 800mm or wire to start with

Hot End Thermistor Wires 2 sets of 2 wires Not sensitive to polarity These wires are likely to need extension; perhaps 300mm I need feedback on this one! I don’t know what the stock length is!

Hot End Heater Wires 2 sets of two wires Not sensitive to polarity These wires are likely to need extension; perhaps 300mm I need feedback on this one! I don’t know what the stock length is!

X End Stop 3 wires Sensitive to polarity This wire will need about 300mm of extension

Y Axis End Stop 3 wires Sensitive to polarity The stock wire should be long enough for this application

Z Axis Proximity Sensor 3 wires Polarity sensitive 12 Volt powered; needs to connect to the +12/gnd connector on the RAMPS board LJ12A3-4-Z/BX may work without a resistor divider LJ12A3-4-Z/BY definitely needs a resistor divider

Extruder Motors These two motors’ wires should be long enough

X Motor This motor moves in two axis It will need an extension; I would guess at 300 mm more

Z Motors Wiring I recommend you wire the two Z motors in series Here’s what it looks like when you splice them properly. The connector that goes to the RAMPS is hanging off to the left. The second Z motor connector is coiled up next to the splices One motor has enough wire, if you splice in the other one like I show you will have plenty of wire. If you run back to the RAMPS with both, get a 300mm extension
