![]() ![]() Hi guys… So I’ve got a strange problem… All of a sudden, my laser cutter wouldn’t Fire. The K40 tube should have no arcing to the little metal collars inside, right?

My K40 has failed half way through a big job (Whisperer estimated 9hr 13m - raster engraving at 100mm per sec and current set at 20% drawing about 2 ma) Is it possible the tube went, or is it the power supply. At that time increasing the power had no effect. I was able to do a few small pieces at that power, then while watching it engrave I saw the dot almost disappear to barely noticable. Plus, it wasn’t engraving at 42%, (usually I use 28-36%) so I started increasing power until it started engraving, which was at 68% (highest I ever had it). It worked fine last weekend, but this past Saturday the power supply was squealing at 42% power, usually I only heard that noise at below 22%. It happened my k40 died after a year and 3 months.
