What's the difference between G0 (rapid) and G1 (cut) for foam?

G0 = rapid travel, wire off (M9). The machine moves at maximum speed between cut features. G1 = controlled feedrate, wire on (M8). The tool generates one M8 per contiguous hot-cut run + an M9 + G0 between runs. Pre-heat dwell (G4 P0.7) fires after each M8 if you set a positive Pre-heat (ms) value in Cut settings — gives the wire time to reach temperature before motion.
