SainSmart Mechanical Endstop

Mechanical Endstops

The recommended firmwares provide a configuration to use mechanical endstops with just these two wires.

Connect GND on RAMPS to C on the switch. Connect S on RAMPS to NC on the switch.

Put the connectors on the motor wires

1. • solder a female connector to the ends of each wire.
   • use the 2.54mm 1x3 housing.
   • Shown is the type used for servos in RC projects. See Stepper Motors for info on motors.

Thermistor Wires

Use a 2 pin 0.1" connector to terminate the thermistor wires.

1. • Connect the cable so the 2 wires go to T0
2. Connect the 2 heater wires to D10 (E0H on older boards) and the + connection above it.
   • If changing to an unverified firmware it is best to verify heater circuit function with a meter before connecting heater to prevent damage to the extruder.
