I am running photovcarve...on roughing out at 30' its fine...never misses a beat but when I change cutter and go to finish (code size increased to nearly 6.5mb from 1.5mb) it almost always skips about a bit and will lose 6mm ish....I've tried slowing things down so that the machine can cope...down to running at 2500mm/min...but when I change the raster angle to zero and just across the work piece it's fine!
