First Framing Check Is Offset? Burn a Reference Card Before Moving Artwork
If framing is offset, preserve the artwork and test a known-size reference card first. Record origin, material height, measured frame, and output offset one change at a time.
Do not drag the artwork to hide an origin error
The 2026 LightBurn thread provides the concrete problem behind this workflow. A June 2026 LightBurn user reports framing about 20 mm from the expected workspace and a measured size mismatch, showing the need to separate calibration and material-height effects.
What a consistent 20 mm shift suggests
A 100 mm card frames at the expected size but lands 20 mm right on two supervised proofs. That stable translation differs from a scale error; moving every design left would hide rather than document it.
Create the known-size reference card
| Check | No-output evidence | Eligible-card evidence | Meaning |
|---|---|---|---|
| bounding size | expected width/height | measured reference | scale check |
| origin | screenshot and job-origin state | offset direction | coordinate check |
| material height | recorded support stack | same stack in retest | height/calibration clue |
| repeat | same frame twice | same measured offset | stable pattern |
Separate frame, size, and material height
- Use an eligible test blank, effective exhaust, stable support, active supervision, and immediate stop conditions.
- Save screenshots of device origin, job origin, and reference dimensions before editing.
- Frame without output, then make one supervised reference mark only where current guidance permits.
- Change one source—origin, scale, or approved calibration step—then repeat the measurement.
A1 Mini framing boundaries
No integrated camera is assumed. The A1 Mini reference relies on measured geometry, documented origin state, eligible material, supervised output, and model-specific support guidance. Use the current A1 Mini details for model context and the measured reference card for origin evidence.
Correct placement before judging the first-sheet tab fit. If projects repeatedly exceed the measured frame, record them in the work-envelope decision log.
First-origin questions
Should I recalibrate immediately?
First preserve measurements and follow model-specific guidance. Do not improvise calibration.
Does this assume an integrated camera?
No. The reference uses measured geometry and framing; no camera feature is assumed.
Can I use scrap plastic?
Only identified eligible material may enter the proof.
