We didn't have the money for a better machine. We looked at proper industrial machines like trotec and epilog but they are four or five times the price. We weren't prepared to import without some kind of back up. Back then HPC seemed to be the only importers who had some kind of infrastructure to look after their machines. There might be more proper importers now. HPC's engineers are very knowledgeable and they are often able to sort stuff over the phone, visits obviously cost money. I wouldn't say daily fettling but weekly perhaps. You should be prepared to adjust mirrors (they can loose focus ) and clean lenses and cutting bars and change water regularly removing bubbles from laser tubes. There is a learning curve but if you have some experience you soon get used to it. They sell an antifreeze we add to the deionized water to stop stuff growing in the water. We had fungus growing in the water early on which blocked the cooling system at the narrowest point which stopped the machine because there is a basic flow switch that shuts the laser off when the water stops. It was our fault cause we didnt change the water enough. All sorts of stuff happened to ours mostly our fault. We use it heavily daily and like a lot of Chinese stuff they are quite robust but are designed to be used by knowledgeable skilled users as they need setting up.
