We just got our Speedy 300 installed in the shop and I'm trying to dial in the Power/Speed settings for the materials that will be cut most often. Logically my thinking was that we would achieve maximum cutting speed for a specific material, by turning the power up to 100%, then turning up the speed as high as it will go until it's just enough to cut through your material. I ran some test and timed the cutting speed, only to find that the lower power/slower speed resulted in the fastest overall cut time. These are my results: (100% Power/9 Speed = 10 seconds), (65% Power/5 Speed = 8 seconds), and (45% Power/3 Speed = 6 seconds). Can anyone explain the logic behind this and give me some pointers on how to dial in the setting for materials?
