I am a cnc router guy interested in getting a laser system as well. Something in the 60-100W category. I have done some research but one thing i dont understand. It seems laser tubes are kind of cheap, a few hundred $. But some lasercutter manufacturers sell laser cartridges for $3000-$15000 for non-industrial machines. What exactly does a laser "cartridge" consist of? Is it not primarily the tube? Can I replace a 60W lasertube for a 100W for only a few hundred dollars?
Another question. It seems Chinese machines are way cheaper than say, Universal or Epilaser, but may have much more problems. There are also those in between that seem to sell chinese-made systems but with warranties and support by english speakers (Omnisign for one). I think I will need the support since I havent too much time to spend figuring things out from scratch. Can anyone recommend one of the better Chinese companies with english tech support? Should I even risk those with my minimal experience?
A good discussion of the Chinese vs Western option would be welcome since the price difference is huge.
Thanks,
B
