Cutting 2mm PETG with 60w Co2 laser - Speeds/Power

Hello

I have a 60w Co2 laser that i would like to cut some 2mm PETG with, I've had a play around with cutting some with varying success and was wondering if anyone has had some success and found a sweet spot. Speed, power and passes would be greatly appreciated.

Thanks

Tom
