ComMarker B4 Galvo Mirror Alignment: Fix Uneven Corners, Weak Corners and Red Dot Offset in Hardware
ComMarker B4 (60W MOPA, JCZ galvo, 110 mm lens) hardware alignment manual: diagnose diagonal corner falloff, vignetting and a red dot that is ~1 mm off, identify the galvo motors, white PVC clamp, driver PCB and red-dot mount from annotated photos, and reseat the mirror assemblies centred and square — red-dot realignment last, never by moving galvo mirrors.
