Personalized Coins on a 100w MOPA Fiber Laser

Coins are one of the main products that I make on the fiber laser. With the recent addition of the 100w MOPA Fiber from @omtechlaser it has taken some time and testing to dial in new settings to match all that power!
These are the settings that work In my two machines but that is not a guarantee that they will work for you. TEST AND TEST AGAIN!
