Precision layout with Snapping, Guidelines and Measure
Choose visual snapping or numeric dimensions deliberately, recognize the active snap point and prove alignment before output.
Panel a design larger than the laser bed without visible seams
Create controlled panel boundaries, registration references and verification points for oversized engraving or cutting jobs.
Mask, crop or convert to bitmap: choose the right image operation
Keep edits reversible when possible and know exactly when LightBurn turns vectors into fixed pixels.
Print and Cut: a repeatable registration workflow
Align a LightBurn project to two physical target marks for printed contours, restarted jobs and work larger than the laser bed.
Broken vector import: extra lines, hidden shapes and wrong scale
Determine whether a problem comes from clipping masks, stacked geometry, units or export settings before rebuilding the artwork.
Build a troubleshooting evidence package that another person can use
Collect the file, machine context, screenshots and Console evidence needed to reproduce a laser problem without guessing.
Tool Layers for jigs, positioning and material-saving layouts
Use T1/T2 geometry as non-output construction guides, then verify how it affects framing and origin before running the job.
Remove overlapping lines without hiding a broken design
Separate exact duplicates from intentional shared edges, verify the output in Preview, and prevent double cutting without damaging the master artwork.
Diode, CO₂, fiber and galvo: identify what kind of laser you actually have
Separate laser source, motion system and controller so settings and tutorials are applied only to compatible machines.
Extraction and ventilation: establish a visible airflow baseline
Separate extraction from air assist, verify the complete exhaust path, and recognize when a job must stop because smoke is no longer controlled.
Identify the material before laser cutting or engraving
Use labels, supplier data and machine guidance to decide whether a material, coating or adhesive belongs in your laser at all.
Laser workshop stop rules: when to stop the job immediately
Recognize the conditions that require an immediate stop, prepare a reachable shutdown path, and restart only after the cause is understood.
Smoke or soot stains the material surface
Treat flame and accumulating smoke as safety events first, then control extraction, approved air assist, energy and surface protection.
Engraving or cutting strength changes across the work area
Use a position matrix to separate material variation, focus height, bed geometry, optics and beam-path causes.
Bidirectional engraving lines do not align
Check mechanics first, then measure and correct a consistent left/right shift with LightBurn Scanning Offset Adjustment.
Laser output flashes or cuts out during motion
Separate project, GRBL power-scaling, speed, connection and hardware causes when the beam appears only intermittently.
Read the Status Bar before changing settings
Use LightBurn’s Status Bar to confirm coordinates, selection context, connection state, notifications, and special modes before troubleshooting.
Precise edits with equations and units
Use LightBurn numeric fields as a calculation surface while controlling the anchor point, proportions, and measurement units.
Date, time, and Cut Setting variables
Use LightBurn Variable Text for timestamps and live layer values while keeping the result understandable and verifiable.
Serial-number production with arrays
Format serial values, assign predictable offsets to array copies, and restart interrupted batches without duplicate numbers.
CSV-driven Variable Text production
Prepare clean UTF-8 data, map zero-based columns, control record advancement, and validate a personalised LightBurn batch.
Variable Text formatting basics
Choose the matching data mode, use the correct placeholder syntax, and test the resolved text before running a batch.
Testing a Release Candidate and downgrading safely
Isolate experimental work, preserve files before a newer version saves them, and return to a stable LightBurn build without guesswork.
A portable LightBurn project handoff checklist
Move a job to another computer without confusing the project file, LightBurn configuration, fonts, and linked assets.
