Thank you russnewcomer! Trumpf are great, based on our experience (~10 years owning and operating several lasers) Mazak have proven to be really reliable and really low-cost in operating kW + maintenance. That&#x27;s why we kept the Mazaks. Of course we are using a nesting program that&#x27;s been leaving something close to 200-300 grams. per stainless steel sheet - and this is the core of our low cost.<p>We tried to explain it as much as possible and give a couple of rules that would save a lot of people from the high heat stuff. It looks that you know a lot regarding lasers and you are more than welcome to stay in touch!<p>Jim
