As I was reading another thread a question popped into my head. Are there any power and speed conversion charts? I was reading a settings pdf for a product like cermark. Their chart had suggested settings for a 35 watt laser and a 45 watt laser. Is there any type of conversion or rule of thumb formulas to convert to a different laser wattage? Example - 45 watt laser speed 60 / power 40. What or how would that be converted to say an 80 watt tube?
