@Curt. I can’t speak for the original author but i think he used whole numbers for the power levels deliberately. These values (0-255) translate to ttl voltage levels of 0-5 volts.5volts divided by 256 gives you increments of about .02 volts. I’m not sure if the human eye could discern a shade of gray burned at 2.56256volts versus 2.56volts. If you conclude that it can then I’ll find the code where this value is rounded and make it so that it matches the JTP decimal placement. Keep us posted..
