Functional educational reconstruction of the LaserPecker 4 beam chain. It shows the selectable 10 W 450 nm blue diode and 2 W 1064 nm pulsed IR sources feeding an inferred shared-path combiner, two qualitative galvo axes, a 150 mm field lens, and the 160 x 120 mm engraving work plane. Both wavelengths are traced together only for comparison; the real LP4 selects one source per job. The combiner, orthogonal scanner flattening, and thin-lens/F-theta approximation are explicitly labeled because public documentation does not disclose the exact internal optical layout. It does not model power, ablation, thermal effects, scanner calibration, or laser safety.
