    The price difference is only worth it if you will be using the new machine primarily for engraving. That is where the Trotec and Epilog machines really outperform the Chinese machines. No contest...

    There is no way that I could get by with a small machine. 24 x 48 would be the minimum I could manage with. As for power I can get by with 80W.

    If you get a DC tube machine then you need to take...

    Certainly not! Unless you mean to solder a terminal onto the wire, than attach the terminal via that screw. That would be okay but crimping the terminal to the wire is the "right" way to do it. In a...

    I was curious so I cut a test gear out of 1/2" BB, I used the 80W laser - if I were cutting a bunch of these I would swap in the 130W. Maybe try different focussing distances too, I focused on the...

    Could be a stretched (or damaged) belt. I think most people tend to over-tighten belts. As long as the belt engages the pulleys properly and is not flopping around when under use (or sagging under...

    When I ordered my machine several years ago I had them build it to a custom size. I would be surprised if that was no longer an option.

    I don't know for sure that a bubble there would cause a real problem - the hot side of the tube is still in contact with water, however I would not be comfortable with it.

    The laser tube does not...

    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 is it about a fiber laser that makes it "WAY more complicated"? Or are you referring to galvo machines?

    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...

    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.
