Treat Tab Cut Power as a control for pulsed cutting across a bridge, rather than assuming it produces one continuous, shallower groove. The useful result is a part that stays attached during the intended handling and separates without unacceptable damage. That result needs a physical sample; a percentage alone does not specify bridge strength.
A September LightBurn discussion about sub-layers and tabs raised this exact interpretation problem. LightBurn's Add Tabs documentation explains the pulsing behavior. The setting name can therefore be misleading if you picture reduced-depth machining.
Give the bridge a handling requirement
Consider an illustrative flat kit with several small decorative pieces held inside a carrier. The carrier will move from the laser to an inspection bench, then into packaging. A bridge that survives removal from the machine but breaks during inspection is unsuitable for that workflow. A bridge that requires bending the decorative piece until it splits is also unsuitable.
Write the intended handling steps beside the sample before testing. Include how the customer is expected to remove a piece. Keep the bridge location, length, stock identity and ordinary cut settings recorded, so a later comparison has a known starting point.
Evaluate a limited representative sample using material and operating conditions approved for your machine. Keep observation continuous during laser operation and use the manufacturer's required ventilation and protective measures. Changing several bridge dimensions and the pulsing control together makes it difficult to identify which change helped.
Compare retention and removal separately
| X1S 2026 kit check | Observe on the sample | Reject when |
|---|---|---|
| Carrier transfer | Pieces remain located through normal transfer | A piece releases prematurely |
| Inspection handling | Bridges tolerate the planned movement | Fine features become stressed |
| Intended removal | Separation occurs at the bridge | Surrounding material tears |
| Edge finishing | Remaining attachment point can be finished | Cleanup destroys the desired contour |
Record both successful and failed samples. An easy break can look attractive until the carrier is handled; a strong attachment can look reliable until the buyer tries removal. Neither judgment substitutes for the other.
Unexpected connected spots outside the designed bridges need a different investigation. A pattern log for isolated uncut tabs helps distinguish deliberate retention from incomplete cuts. Do not increase a bridge control to compensate for unrelated cutting inconsistency.
Account for the finished kit
The TYVOK X1S 2026 offers an 800 × 800 mm starting configuration and an 800 × 2000 mm extended configuration on its current page. The selected size can provide room for carriers, but neither area establishes a usable bridge setting for your stock. Confirm the installed configuration and supported software setup before applying this workflow.
For box components, also distinguish the attachment scar from deliberately proud finger ends. Planning finger length for flush sanding addresses material left for finishing after assembly.
Questions about breakaway parts
Can the same Tab Cut Power percentage be reused on another material?
Do not assume equivalent retention. Thickness, composition, grain and the surrounding cut process affect the result. Preserve the old sample record, then qualify the new stock separately.
Does a bridge that breaks cleanly prove the kit is ready to ship?
It proves only that removal worked in that sample. Check the actual carrier handling and packaging sequence too, without treating a workshop check as a certified shipping or strength test.
