Laser did not cut through

Diagnose identity, focus, optics and setup before adding heat.

Applies when

For a verified cuttable material on the exact supported machine.

Transfer warning

A failed cut does not authorize a slower/higher-power record from another machine.

Controlled laser failure samples arranged for visual diagnosis

Before power

Verify the context

Stop and let the sample cool.
Verify product and measured thickness.
Check focus procedure, flatness and lens/nozzle cleanliness by manual.
Compare exact official/default material workflow.

Bounded workflow

Run one defensible test

Classify failure as uniform, local/void, direction-specific or progressive.
Test official material/default parameters exactly as the manufacturer directs.
If official material also fails, follow machine power/optics support—not a community setting.
If only the custom sample fails, reject or reclassify the material.
Log the failed result and one next test.

Success signal

What counts

The cause is bounded to material, setup or machine without unsafe escalation.

Failure branch

What to test next

Repeated passes without diagnosis increase heat and hide the cause.

Safety boundary

Mandatory stop condition

Stop for flame, fumes, lens damage, collision, power-drop suspicion or any machine fault.

Manufacturer instructions override this page. Read the safety policy.

Eligible records

3 qualified exact-context records

Each item passes qualification plus this page’s material, operation and thickness constraints.

qualified test recordXTD1-10-BASSPLY-3-CUT-002

xTool-launched basswood plywood · cut

xTool D1 · 10 W blue diode · 3 mm

Speed6 mm/sPower setting100%Passes1

Source reference row supplies a one-pass cutting parameter; edge quality is not reported.

Transfer limit: Only for the exact source-named xTool product on xTool D1 10 W. A generic 3 mm plywood label is insufficient identity.

How evidence is qualified

qualified test recordXTD1-5-BASSLAM-8-CUT-019

Basswood laminate · cut

xTool D1 · 5 W blue diode · 8 mm

Speed1 mm/sPower setting100%Passes10

The official D1 5W workbook records that the 8 mm basswood laminate was not cut through after ten passes at the listed setting.

Transfer limit: A failed observation only for the source-claimed 8 mm basswood laminate on xTool D1 5W at the exact listed row. Not a cue to add passes, and not transferable to solid basswood or plywood.

How evidence is qualified

qualified test recordXTD1PRO-20-BASSPLY-3-CUT-013

Basswood plywood · cut

xTool D1 Pro · 20 W blue diode · 3 mm

Speed6 mm/sPower setting100%Passes1

Official xTool material library reports a one-pass cut reference for 3 mm basswood plywood on D1 Pro 20W.

Transfer limit: Only a starting test for xTool D1 Pro 20W with source-matched 3 mm basswood plywood. Do not transfer to D1, another module, generic plywood, or another controller scale.

How evidence is qualified

Supplemental evidence

Workflow or performance references

These items can explain applicability, but they are not qualified test records, do not count toward coverage and are never labeled exact-context.

tutorial-exampleXTD1PRO-20-SOFTWOOD-4-CUT-010

Softwood · cut

xTool D1 Pro · 20 W blue diode · 4 mm

Speed4 mm/sPower setting100%Passes1

Tutorial example says the cut works on wood but does not pass through knotholes.

Transfer limit: A tutorial example, not a lab recommendation. Do not apply to plywood, MDF, hardwood, a different D1 Pro module, or safety-critical production.
