[LS158] Why Small Test Grid Squares LIE

This episode starts with the crew comparing beam combiner setups before Alex admits he’s officially done aligning red dots and is moving to SPT TR tubes with built-in combiners. Matt works on brass nameplates live and breaks down his batching workflow - why repeatable templates, grouping, and frame previews save hours. From there, the group dives deep into ammo can engraving (CO₂ vs fiber, smoke management, respirators), then pivots into material settings: scan offset adjustment, power scaling on corners, why small test squares lie, and how min/max power affects burn when machines accelerate or slow down. Several viewer questions lead to discussions of engraving plastics, circles vs squares for tuning, test grids, and pricing small design work - plus why quoting government jobs can become a nightmare of revisions.
