    It sounds like your chiller is a few years old. Is it pumping the water strongly, have you checked the flow? The water pump can get clogged up reducing flow. Changing out the water does not fix that....

    I'm curious to hear some solutions.

    The only one that I know of is to cut slower in order to put more heat into the edge, or use another tool such as a jointer to shave a bit off. I have used...

    A 67 as pulse is incomprehensibly short, but it is not the same as firing 15 million billion pulses one after the other. It is an extremely short duration pulse, not a frequency. Sure, to illustrate...

    That would be 180 terahertz, six times the frequency of CO2 laser light. It would be turning off an on several times per wavelength oscillation. I think there must be some mis-remembering of the...

    Perhaps I am being dense... it sounds like you are talking about galvos, which are not limited to fiber lasers. It seems to me a gantry style fiber laser ought to be pretty similar control-wise as a...

    What you describe is using a laser to resaw a plank of wood. No laser would be able to make a clean cut through 12" of wood.

    There are indeed lasers with articulating heads that enable them to...

    I know the developer, I have never known him to be the type to bite people's heads off. I am curious as to the exact words said that led you to feel that way.

    The Reci 80W tubes are about 48" long, the 100W tubes are about 55" long. They are both about 3.5" in diameter (wide body). Other makes of tubes are longer and narrower for the same power, and I...

    Before we moved out of the city I had purchased some 4" abs pipe and a sweep (long 90 deg turn) so that I could exhaust the fumes straight up. I don't know how well it would have worked since I never...

    I use a Gast compressor, like what is used in gas station air filling stations. No tank. The compressor line goes into a tee, one side of the tee has a valve which controls how much air gets dumped,...

    That looks like a tube failing, I don't think that has anything to do with G.Weike. Same thing happened to my first 130W Reci tube. It was replaced at no cost to me within a few days.

    I was cutting dozens of spur gears out of plywood, each about 7" in diameter with about 120 teeth. Each tooth...

    If you will not be making a steady income, go with an 80W Chinese machine with a fat body tube (like Reci) and a Ruida controller*.

    You mean a "dongle"?

    None of my machines have required a dongle, if you cannot find an easy solution I think it would be worth just replacing it with a new Ruida controller.
