On a newly assembled DIY claw machine, setting claw strength should come after checking assembly, wiring and movement. A claw that misses a prize, binds during lifting or releases in the wrong place may have a setup problem that a higher strength setting will not fix.
This guide is a first-setup and acceptance checklist for your completed cabinet. Use the instructions for your exact kit and mainboard for menu access and parameter values. For explanations of strength controls, see our claw strength settings guide.
1. Confirm Your Installed Components
Record the kit edition, mainboard model and version, claw mechanism and intended prizes. Check the packing list and wiring diagram against what is actually installed. Do not assume all 25.7cm, 53cm and 71cm kits use interchangeable components or identical settings.
Confirm cabinet clearance, guide-rail alignment, the lifting path and prize chute before grip testing. Disconnect power before handling connectors or moving parts. Have qualified help handle unfamiliar electrical work, and keep hands clear during powered tests.
2. Record the Starting Configuration
Photograph or write down the board's original settings before changing anything. Locate the matching manual and use its documented setup procedure. Do not perform a factory reset unless the specific instructions require it and you understand which settings will be lost.
There is no universal starting percentage for plush toys or commercial use. Use the documented configuration for the installed board, rather than borrowing values from another machine.
3. Separate the Parameters
- Grab and hold controls: where supported, these affect different stages of gripping and carrying a prize. Names, units and behavior depend on the board.
- Release or movement timing: identify what a timing parameter actually controls. A label such as drop time should not automatically be treated as grip duration or a way to increase prize deliveries.
- Game time: the time available to position the claw is distinct from its gripping force.
- Payout-related controls: where available, these are not a guaranteed prize-per-play ratio and should not be confused with mechanical condition.
Only adjust controls documented for your actual board. Do not change the power supply voltage to compensate for a weak grip.
4. Check a Complete Play Before Fine-Tuning
Use the board's documented test or play procedure. A supported service mode may help check operation, but do not assume it behaves identically to paid play.
- Confirm joystick movement and the claw's ability to reach the intended prize area without binding or striking the cabinet.
- Observe lowering and closure around a representative prize.
- Observe lifting and travel toward the chute.
- Check that release occurs in the intended location and that the prize can pass through the chute.
- Confirm the machine completes its documented return or homing sequence.
Where fitted, test the prize sensor according to its instructions. Do not assume every kit includes one. Record the stage where any fault occurs before changing grip settings.
5. Make One Documented Change at a Time
Use the intended prize mix and record size, shape, surface and placement. If a supported grip setting needs adjustment, follow the board's permitted range and increments. Do not prescribe a universal five-percent change.
Repeat comparable tests, recording both successful delivery and where unsuccessful plays fail. If a change does not address the observed problem, restore the recorded setting and investigate the relevant assembly, wiring or mechanical issue. For a fuller diagnostic process, use How to Test and Adjust Claw Strength on a Claw Machine.
6. Keep an Acceptance Record
Before putting the cabinet into normal use, keep a record of the board version, final settings, prize types, test mode, observations and unresolved issues. Check that closure, lifting, travel, release and return operate as documented for the machine.
A short test checks operation; it cannot establish a guaranteed long-term win frequency. For commercial use, monitor actual plays, prize deliveries, downtime and costs over time, and check the requirements for your location. Do not accept a build simply because twenty plays happen to produce a preferred payout ratio.
When to Ask for Help
Stop testing if movement is unpredictable, parts become unusually hot, or the board's documented behavior does not match the machine. Do not increase settings to mask a fault.
Contact Hiclawcrane with the kit edition, board photos, current settings, prize details and a short video showing the stage that fails. For replacement components, check arcade spare parts and confirm compatibility before ordering. If you are still planning a build, compare the included components in our DIY Claw Crane Machine Kits.
Frequently Asked Questions
What strength should I start with on a new DIY build?
Use the matching board's documented configuration. There is no supported percentage that applies to every kit, claw and prize.
Should I increase strength if the claw drops a prize?
First identify where it drops and check prize fit, placement, mechanism condition and the relevant board behavior. A dropped prize does not identify one setting as the cause.
Is drop time the same as hold strength?
No. A timing control and a force-related control are different. Verify each label's function in the installed board's manual.
Are twenty test plays enough to confirm a win rate?
No fixed test count guarantees a long-term win rate. Initial testing should confirm documented operation, followed by ongoing observation under real conditions.
