    Hello Ake
    Sorry I can't guess what is causing the loss of power. You asked about tuning the power supply. I recall that Rodne Gold used to do this in-house with his GCC's. He might have some info...

    In CorelDraw, click on the open path, then select Arrange -> close path -> closest nodes with straight lines. (Other options might work okay too.) If there is an open path (say .001" gap) this...

    Brian, I can't give advise on the two machines but just wondering what you have in mind for fume extraction if using an open bed. This would be an important factor in your selection to ensure you...

    The spot size will increase quite a bit with the 4" lens so power density will go down. I have doubts that a 4" lens would be beneficial for acrylic. The only thing I use my 4" lens for is cutting...

    It is hard to say if you can do anything in Alibre to improve it - there might be, but it could be time consuming to find a way. What I would likely do is segregate each contiguous path in CorelDraw...

    Yes, it is amazing how fast fiberglass can dull a sharp edge or tool. The copper itself is no problem; it is the glass. I would probably try waterjet to do something like this.

    You are asking me Gary? You won't find anything about using lye in the II-VI catalog. I would highly doubt any lens manufacturer would recommend using lye to clean a lens.

    In the II-VI catalog there are detailed instructions for cleaning lenses that are mildly to badly soiled. There is a lot of other interesting technical info in the II-VI catalog concerning lenses...

    I just tried this idea on Arial test by converting the string to a bitmap at 500 dpi and then centerline tracing. Even with a simple font such as Arial the result was not very good. The "A" and "S"...

    I don't think a single-line (single-stroke) font is compatible with the requirements of a TrueType font. I investigated this some years ago and it seems like True-Type fonts require the font...

    Gerti -welcome . . .
    Does the laser do the same thing if you place the image justified to the right side of the bed? If it does the same thing then it would seem there is some kind of problem with...

    Tim, you are sure you can get a 4" pipe all the way up to the roof? If it is a "wet wall" then it will accomodate a 4' pipe but a standard 2"x4" wall won't. Best to use smooth pipe if you can. ...

    I have always thought that old threads should be closed automatically. Why not close it for new posts after 12 months? After the first person mistakenly posts, it turns into a current discussion. ...

    Marty - sure, it's possible, but you want to check out any other possibilities first. How was the laser stored? Was it stored "inside" i.e. normal environment for operation? If it experienced...

    Rodne is correct, a loss of 50% power with the Synrad points to one of the RF boards failing. But some people have successfully repaired the RF board. If someone wants to tinker, the repair can be...

    Kev, I'm not sure there is an extra burn from mirror 1 or that is just dirt on the test card.

    Agron, I believe that mirrors 2 and mirror 3 are identical. (If I remember correctly mirrors 1 and 4...

    If you could buy the exact motor that the manufacturer uses (Trotec in this case) then you might have a chance at making it work. But a lot of time the motors are custom-made for the application...

    Agron, since the carriage is getting hot it would seem that the laser energy is not passing through the optics properly - the mirror holder will heat a small amount but you should never have a...

    Mayo, there are too many things going on to be able to do much math on the speed and power parameters. There are some old threads on this topic if you choose to read more. Although I assume that for...

    It would seem that the lens has become extremely fogged up with some kind of residue. It should transmit visible light very well. Perhaps something you were cutting has deposited on the lens. You...
