CNC cutting and engraving¶
A repeatable M-Series job is a chain: correct source → correct file scale → correct layer/process → healthy optics/nozzle → calibration → simulation → framing → supervised run → measured result. Skipping a link makes later parameter changes hard to interpret.
Choose the task¶
- Cut or engrave in mLaser: the complete file-to-part workflow.
- Calibrate the floating cutting head: establish a trustworthy height reference.
- Use flight cutting: faster repeated-feature processing after ordinary cutting works.
- Frame and place a job without a camera: prove location with emission disabled.
- Fix dross, blowouts, and incomplete cuts: a symptom-first diagnostic tree.
- Check X/Y scale and kerf: separate motion scale from cut compensation.
Do not tune around a fault
More power is not a substitute for the right source, a clean protective window, a centered nozzle, correct focus/height, adequate gas, and a flat supported sheet. Establish those conditions first.
The pre-run gate¶
Before every new material or machine change, answer all of these:
- Is the material positively identified and safe to laser process?
- Is the intended fiber or CO₂ source selected?
- Are extraction, cooling, assist gas, and safety circuits normal?
- Are the protective window, ceramic, and nozzle clean and undamaged?
- Are units, drawing dimensions, path order, origin, and process layers correct?
- Did calibration, simulation, and a no-emission frame all pass?
- Is someone staying with the job with a clear stop/fire response?
When a cut fails, preserve the failed coupon and record both software settings and physical setup. That evidence is much more useful than “it cut badly.”
