Building a claw machine from a DIY kit takes a plan for both the kit components and the cabinet you will put them in. This guide follows the major stages from checking the parts to a first test play. The exact order, mounting points and connectors depend on your selected kit and cabinet; use their specific drawings and instructions rather than treating this as a universal assembly manual.

What You Need
- A Hiclawcrane DIY kit in the edition that fits your intended cabinet and prizes; 25.7cm Mini is a separate compatibility category.
- A cabinet or enclosure, suitable panels and prize chute sourced or built separately.
- Cabinet tracks or guide rails matched to that enclosure; these are not included in the DIY kit.
- The selected kit's included-parts list, mechanical instructions and wiring diagram.
- Tools suitable for the cabinet materials and supplied fasteners; a multimeter can help verify documented low-voltage connections when used correctly.
- Enough time for cabinet construction, installation and testing; there is no universal two-to-four-hour build time.
Step 1: Unbox and Inventory Components
Check the exact kit against its packing list before you start. Depending on the edition, identify its gantry components, claw assembly, mainboard, controls, payment device, power supply, wiring harness, lights and any included prize sensor. Do not assume every edition has the same count or type of each component.
Separate cabinet materials: steel or other frame panels, acrylic display panels, cabinet-matched tracks or guide rails, prize chute and other enclosure parts must be planned separately. Do not count them as missing kit items simply because they appear in a full-machine build guide. See the Complete Claw Machine Parts Checklist as a build reference, not the packing list for every kit.
Step 2: Plan and Assemble the Cabinet
Confirm the cabinet's internal dimensions against the selected gantry's complete travel path, mounting points, claw drop and prize chute. Plan control-panel, payment-device, ventilation and maintenance access before fastening panels. If building a cabinet, assemble its base, sides, front and top according to your cabinet design; a DIY kit does not supply a universal set of frame panels, feet or brackets for this step. Check that the structure is square and secure before mounting moving parts.
Step 3: Fit Cabinet Rails and Gantry Components
The kit's gantry components and the cabinet-matched tracks or guide rails are not the same thing. Source rails for the enclosure separately and follow the selected kit's mounting diagram. Check rail alignment, travel clearance, motor and drive-belt placement and any included limit-switch positions for the actual version. Do not assume the X and Y assemblies all slide together or that switches must be placed at both ends of every axis in the same way.
Step 4: Install the Claw Mechanism
Identify the claw head, lift mechanism, cable or string path and claw-drive components supplied with your edition. Mount and route them as shown in that kit's diagram, with clearance throughout the drop and return. Do not assume every claw head attaches directly to a Z-axis motor shaft, uses the same solenoid or has a spring-tension adjustment. For compatible replacements, check the exact part and pack quantity in arcade spare parts.
Step 5: Install the Control Board and Harness
Mount the selected board in a protected, accessible cabinet position. With power disconnected, identify the board and power supply ratings, then trace each diagrammed harness branch: motor/driver connections, limit inputs, joystick and buttons, payment device, any prize sensor, lights and speaker. Check each connector's pinout and component voltage instead of relying on wire color. The board typically uses 5V DC in Hiclawcrane systems; other circuits and gantry motors vary by model. Confirm all outputs against the exact kit diagram before power-on. See the DIY Kit Wiring Guide.
Step 6: Fit the Payment Device
Position the included coin acceptor or selected payment device in a cabinet opening that fits its mounting and access requirements. Check its supply, signal type and board input against the selected edition's wiring diagram. For a bill acceptor, the cabinet must have space both to mount the validator and to store banknotes. If buying a replacement coin acceptor, check compatibility and whether it is sold as a pack; do not treat the contents of a multipack as individually available.
Step 7: Install Panels and Lighting
Fit separately sourced acrylic or other cabinet panels to your enclosure, allowing access for service. Mount the lighting supplied with your specific kit and route its wires clear of moving parts. Check the lights' rated supply and the diagram before connecting; do not assume one 350W power supply or one LED controller works with every kit size.
Step 8: Power On and Test
- Before power-on, inspect wiring, connector seating, cable routing, moving-part clearance and the documented supply ratings. Have qualified help handle mains-side wiring if needed.
- Use the kit's initial power-on procedure and check the board and lights for the functions actually included.
- Test joystick directions and gantry travel within the planned cabinet clearance; check the specific limit-input and homing behavior.
- Test claw lowering, lifting and grip using the selected board's documented settings.
- Configure and test the included payment device with accepted coins or banknotes and the board's input settings. Do not rely on a universal ten-coin calibration rule.
- Where fitted, check the prize sensor's count by passing appropriate prizes through the chute. The mainboard tracks plays separately.
- Run complete plays with the intended prizes and verify chute delivery, payout settings and access for restocking and maintenance.

Frequently Asked Questions
How long does assembly take?
It depends on the cabinet, rail preparation, kit edition, tools and builder's experience. Allow time to test the full machine; do not assume a standard two-to-four-hour build.
Do I need any special tools?
That depends on how the cabinet and rails are made. Check the kit's fasteners and the cabinet design for suitable tools; electrical checks should follow the exact wiring diagram.
What if a part is missing or damaged?
Compare the delivered contents with your kit's packing list, then contact Hiclawcrane with your order details and photos. The team can check the issue and advise on next steps; replacement terms depend on the order and applicable policy.
Is building a DIY claw machine difficult for beginners?
A first build is manageable with the correct cabinet plan, kit-specific instructions and tools, but it is not just a plug-in project. Check the wiring diagram and seek qualified help for unfamiliar electrical work.
Which kit size should I choose — 25.7cm, 53cm or 71cm?
Start with cabinet internal space, travel path and intended prizes. The 25.7cm Mini is a separate compatibility category; compare the exact kit's components and cabinet requirements. See the kit comparison page.
Can I use a DIY kit to build a machine for commercial use?
Yes, if you build a suitable cabinet, match components to the selected kit and check the requirements for your location. Do not assume every edition includes dual coin acceptors, identical voltage ratings or a complete ready-to-run enclosure.
