im working with 1.5mm plywood and using a 50.8mm lens for cutting.
just wondering if anyone has experience cutting with a F.L
of 25.4mm and if it would be a better suited lens for cutting 1.5mm plywood,
the 50.8mm lens is leaving burn marks,i dont have the option of being able to use an air compressor and thinking the 25.4mm lens has a smaller spot so less chance of a flame appearing but i dont know if its depth of field is
suitable for cutting 1.5mm plywood,
