    Re: Did I get ripped off with my 100W X700?

    In regard to the tube, that is shady but a common practice among ebay sellers to quote a peak power rating versus the true usable rating (use without quick shortening of the life of the tube). ...

    Re: Laser not cutting accurately. PLEASE HELP

    Does your software have a step length adjustment function setting? For example, if you go into the vendor settings within in the Ruida's RDWorks software, there is a step length figure and when you...

    Re: CO2 Laser Bodor

    I think it is going to be less about the nozzle and more about the focal length of the lens. If you have the standard 2" lens in your machine, a 4" lens might do a better job with the relatively...

    Re: 80W efr tube. How hard can I drive it?

    There are different models of 80w EFR tubes. For mine, you never want to exceed 28 mA and EFR states that 25 mA is the maximum if you want to get the maximum life out of your tube. Go to the Lasea...

    Re: Measuring the power output of the laser tube

    Follow robertk925's advice. Russ' device costs less than $70 to put together and works great.

    Re: Question About Max Current for 100 watt laser

    Look at your tube to get the model/series number. Then go to the RECI website and you will be able to look up the specifications for your tube.

    Re: RDC6332G no connected devices !!

    Most laser users on this forum use the newer 6442G or 6442S controller so there probably just aren't that many people here with experience using that controller.
  13. Re: I always want to support enthusiasts and hobbyists ...

    My guess is that you "over drove" your tube/power supply and killed the tube. Very common with these machines if you ran it at 65% power or more, due to the fact the tube's rating is not truthful. ...

  24. Re: Rabbit Laser vs Boss Laser LS 2436, looking to buy, need advice

    Re: Chinese laser Fault, advice please

    Some power supplies have component boards with a very small glass tube fuse on them. At this point, you might as well open up the first power supply to see if you can find a fuse that is replaceable.
