Connect Motors

By default the motor current is set for Nema23, 2.8A motors - verify your motor max current and adjust the current settings if needed. Your motors should run warm to the touch, but not hot

Warning: Never connect/disconnect motors to a powered-up controller. Always turn off power before connecting/disconnecting accessories to/from your xPro

• How to: verify coil wires
• Simple verification of 4 wire stepper motors:

1. Using a multi-meter, resistance Set the Ohmmeter to the lowest resistance scale.
2. Attach one of the wires to the meter and, in turn, check each of the remaining three
3. Mark the wire that gave a reading and mark the first wire you started with (coil A)
4. The remaining two wires will be coil B

• Connect stepper motor wires to the supplied 3.81mm connectors and plug in to the corresponding receptacles on the xPro-V5

NOTE: switching the polarity of either (one) coil will reverse the stepper's direction - also the color codes shown below may not apply to your particular Motors

Connecting Limit Switches

Warning: Incorrect wiring can short V+ to GND causing damage to your controller: Double check wiring before powering on

Use a 2-wire cable to wire up regular microswitches
