Hello just bought a used Laserpoint 2 to learn and start making decals I was running it at 600 speed and 170g pressure when I was cutting on scrap 651 oracal scraps that came with the cutter well I purchased 951 not realizing I was using 651 before I cannot find the sweet spot setting. Either it cuts to deep and pics the vinyl up after it finishes a cut and messes up the letter or it doesn't cut deep enough it cuts enough to weed but some parts don't fully cut through. Any advice running it currently at 300 speed 100g pressure.
