Just be aware you could lose customers to the guy down the street who has a faster machine, or prices by the job, or... the customer won't care if his previously $100 job that now costs $120 is due to you needing to slow down your machine to prevent damage. Making more money at the customer's expense doesn't make for a happy customer. Maybe you should have worded it "I will need to charge more to make the same hourly profit". But that's not the same as "making more money".
