Absolute Coordinates or User Origin? Make a One-Page Setup Card
Choose one documented coordinate workflow, record home and origin behavior, place a disposable blank, and frame before the first supervised operation.
Coordinate-mode confusion remains a common first-machine problem, especially when software and controller references are mixed. A one-page card gives unexpected travel an immediate stop-and-verify response. Demand source.
Understand the two references
Absolute-coordinate work places artwork relative to the machine's established coordinate space. User-origin work places it relative to a deliberately set user reference. The exact names and behavior depend on current controller and software documentation, so the setup card must record the chosen mode and origin procedure.
When travel is unexpected
Stop immediately. Do not let the laser fire while diagnosing. Verify the selected coordinate mode, machine homing state, user origin, file placement, and any saved start-from setting. Remove or protect the material and perform a safe powered-off clearance check or documented frame check.
Make the card operational
Record the normal startup order, expected home position, how origin is set, where the file sits in the workspace, and the stop response. Never copy another machine's coordinates. Resume only when motion matches the boundary and current guidance.
Evidence record for coordinate setup
| Decision point | Evidence to keep | Hold condition |
|---|---|---|
| Mode | absolute or user origin | do not switch mid-job |
| Origin | machine and file reference | mark the setup card |
| Blank | known safe disposable sample | keep clear of travel limits |
| Frame | boundary fully observed | stop on unexpected direction |
Release rule for coordinate setup
Allow laser operation only after the chosen coordinate mode, homing state, origin, file placement, and safe boundary behavior all match the documented setup card.
A1 Mini boundary for coordinate setup
A1 Mini is a compact blue-diode starting point for small-craft learning. Confirm live configuration, software, controls, accessories, material guidance, guarding, ventilation, and regional availability. Compact size does not make unidentified materials safe or remove the need for active supervision and fire controls. Review the live product page for the current regional configuration before purchase or use.

Buyer questions about coordinate setup
What is the difference between absolute coordinates and user origin?
Absolute uses the established machine coordinate space; user origin uses a deliberately set user reference under current software/controller guidance.
Why did the laser move away from my material?
Stop immediately and verify mode, homing, origin, file placement, and start-from setting before a safe boundary check.
Can I copy another user's origin settings?
No. Coordinate state is machine- and setup-specific.
