BenchWeld's laser references cover the diode and CO₂ machines hobby and small-shop owners actually run, plus the LightBurn software that drives most of them. The focus is the troubleshooting intent — what to do when a documented procedure won't complete — not a rewrite of the manufacturer's how-to.
A large share of ‘laser’ problems are really LightBurn problems — camera alignment that won’t capture, a device that won’t connect, settings that won’t take — and those fixes are nearly identical across brands because the software is the same. Mechanical and optical problems (weak power, a beam that won’t cut through, alignment that drifts) live in the machine. Separating ‘the software won’t do X’ from ‘the beam or mechanics are wrong’ tells you which guide to open and stops you from recalibrating hardware that was fine.
For step-by-step calibration and setup, the official LightBurn and machine docs own the top of the search results, and they should — they’re authoritative. Where a third-party reference earns its place is the failure case: the capture comes back black, the wizard rejects the pattern, the overlay is right but the engraving lands off. That’s the intent our guides target, built from real forum threads where the documented procedure broke and someone found the fix.
Diode machines (xTool and similar) are usually about the lens module and power for cut-through problems; CO₂ machines (OMTech and the like) bring tube end-of-life and mirror alignment into play. The symptom can read the same — ‘it won’t cut through anymore’ — but the parts and the diagnosis diverge, which is why the guides stay machine-specific.
