I use stacks of magnets for almost every job… my laser doesn’t have a honeycomb bed… but I ordered one (will arrive on monday) because I think I have a use for it with cutting and engraving leather.
My orginal bed is made of a sheet of aluminium which makes using the magnets a bit harder. (there are some steel supports for the aluminium so the magnets DO have a function)
But my next step is to put a steel sheet in instead.
