Start With the Wiring Diagram for Your Exact Kit
A DIY claw machine kit connects a power supply, control board, X/Y/Z gantry motors, claw assembly, position switches, payment parts, and player controls. The connectors, voltages, pinouts, and optional accessories depend on the kit edition and board version. This article is a checklist for reading the correct diagram and preparing for a controlled test, not a universal terminal-by-terminal wiring instruction.
Record the product edition and the labels on the board, power supply, motors, and connectors. Use the wiring diagram supplied for those exact components. If labels are missing or a connector does not match, stop and request the correct diagram or technical confirmation rather than guessing from wire color or plug shape.
Separate Mains AC From Low-Voltage DC
The power inlet, power switch, fuse, and AC input side of the power supply are mains-voltage areas. Connection and electrical service there require appropriate qualifications and compliance with local rules. Do not follow a generic instruction to attach mains conductors or change an input selector without the exact supply documentation. Keep the kit disconnected from power while inspecting or handling connectors and mechanical parts.
In Hiclawcrane systems, the supply may provide 5V, 12V, 24V, and 48V DC for different components. The mainboard generally uses 5V DC; 12V commonly serves illuminated joysticks, buttons, and prize or win lights. Some gantries use 24V motors and others use 48V motors. The 25.7cm mini is a separate compatibility class. The claw drive must also match its actual board and assembly. A wire's color alone does not establish voltage, polarity, or pin function.
Identify Each Low-Voltage Connection
- Board supply: verify the board's rated input and connector against the exact board and supply labels. Do not apply a blanket 12V board-input rule.
- Gantry X/Y/Z: match each motor, its rated voltage and drive connector to the correct model-specific output. A connector can include more than motor-drive conductors; do not swap plugs or motor wires as a generic way to reverse movement.
- Claw assembly: identify the installed claw and drive circuit from the diagram. Do not assume every claw uses a two-wire DC motor or that reversing wires corrects an open/close fault.
- Position switches: check each switch's intended input, contact type, connector, and mounting against the model's diagram. Do not assume all switches share one contact configuration or identical home locations.
- Payment and player controls: confirm the actual coin acceptor's supply and pulse configuration, and the joystick and button input labels. Do not assume one pulse per coin or a universal connector pinout.
- Lighting and optional parts: use the specified accessory output and rated supply. Prize sensors depend on the edition; do not add one merely because a kit has a particular gantry size.
Before the First Power-On
- Confirm that the enclosure provides the required mounting space, travel clearance, and cabinet tracks or guide rails; these rails are not included with the DIY kit.
- With power disconnected, confirm connectors match the board diagram and sit securely, cables are routed clear of moving parts, and there are no exposed or damaged conductors.
- Have a qualified person verify the AC-side installation and the actual supply and component ratings. Do not energize equipment with an unresolved label, polarity, grounding, or connector mismatch.
- Keep hands clear for a controlled power-on. Observe the display, payment registration, joystick directions, X/Y/Z movement, claw cycle, and return behavior according to the specific board instructions. Stop if a motor moves unexpectedly, a cable catches, or the carriage strikes the cabinet.
Do not assume all three axes must perform the same homing motion immediately at startup. The sequence varies by board and assembly. Record any symptom, switch off, and diagnose against the actual wiring diagram before changing a connection.
Frequently Asked Questions
What if an axis moves in the wrong direction?
Stop the test and check the joystick input, axis assignment, connector pinout, and board settings against the exact wiring diagram. Do not reverse motor wires or exchange connectors as a generic fix.
What if the claw opens or closes at the wrong time?
Stop and identify the claw assembly and board drive circuit, then check the relevant input, connection, and model-specific sequence. Do not assume the claw is a two-wire motor or swap wires without its service procedure.
What if there is no display or movement after power-on?
Switch off and check that the installation is complete, connectors are seated, and the rated supply and board match the diagram. A qualified technician should perform model-specific electrical measurements; no display alone does not prove a bad board or fuse.
Can I extend the kit's motor wiring for a larger cabinet?
Do not approve an extension based on wire gauge alone. Confirm the motor current, wire length, voltage drop, protection, connector rating, routing, and kit manufacturer's instructions before changing a harness.
