Sarason, I think the OP is wanting this list after the Samsung machine or their EasyOLP program has optimized the feeder list for their particular machine. I think in the menu on the machine (at least on the CP45 series) there is a print feeder lis

Why can't you place the entire job the same day you paste it? I can. But setting up and properly cleaning the stenciling machine takes 2-3 hours. We only run one shift. If we do that every day we're spending most the time on setup+teardown. Much
