Necessity is the mother of all inventions! I love the concept of a floating cutting head to compensate for an uneven bed.

Very nice video! Lots of fun to see.

Seeing this amazing machine, I discovered that I need a nozzle just like yours. Spectacular.

I hope it works as well for you. Special problems require special solutions

Nice video Russ, question about laser cutting power supply's, has yours ever lost a bit of power due to age? ive replaced my tube recently, and its marginally better than before, im wondering if the power supply looses efficiency over time? or would it just die? thanks

Hi David No, I have several machines and only one HV PSU has ever failed. There is nothing in between working and not workin Unlike the tube. That is just like an ink cartridge it will work well with no loss of performance untill the ink has alsmost run out. In the case of a glass tube it is the CO2 gas that gets transformedover time to CO. You will notice the loss of power a week or two before it drops to zero output. The pink beam will no longer be a bright pink but the beam will still be there so people are puzzled as to why no power. It is the ionized nitrogen in the gas mix that glows pink but when it becomes contaminted with some of the oxygen stripped from the CO2 it becomes an almost white beam. A sure sign of a dead tube. A marginally bettter tube could be a sign of replacing a B grade tube with another (newer) B grade tube. Thereare many of f these tubes available and unless you know what you are looking at or buy from a reliable A grade tube source , it's a real lottery. A simple test that will tell you if your tube is a factory reject is demonstarted inthe his video You will need tome thick (say 10mm acrylic. If you do not have this but maybe have 3mm acrylic then cut 4 sqares 25mm and superglue them into a block A pointed trumpet shape is what you should see but a blunt bullet shape indictes something lass than ideal kzbin.info/www/bejne/pJKzq3mpqtuIiLc
