    Does anyone have experience with with a high power lasers for engraving recommendions

    I am looking to buy at least up to a 30 watt engraving laser ( to use on a 3D printer format )
    ( 24 volt format preferred will use 12 volt format )

    I looking for recommendations for a good laser head ( with heat sink ) with PWM control ( PWM controller separate from the laser is preferred ) I have googled this to find as much information as I can but what I can not find is good recommendations for just any brand

    I do have the circuit for the interface to the 3D printer controller board for the PWM output for the input to laser ( optic sensor circuit ) which I have to make this circuit board

    Now for the buck converter for the laser 24 volt to 12 volt

    I not sure what type to use because I saw where someone has used one but you had to hook up the buck converter a special way for it to work correctly

    I looking to spend up to $200.00 ( I would consider spending more if it for quality reasons )

    Does anyone who visits this forum can give me some recommendations on a good quality laser product and where to buy it

    24 volt laser head with heat sink ( 24 volts so I do not have use a buck converter)
    PWM interface ( 0 to 5 volts ) ( PWM controller board separate from the laser head preferred )
    30 watt maximum output ( range of wattage I am looking for 10 to 30 watt )
    High quality ( this is a must requirement if possible )


    I would like be able to use PayPal to pay for this purchase if preferably possible

    Thanks for any input anyone has about this subject

    These two repairs where found with a ESR meter...> Temp at 50*F then at 90*F the ESR reading more than 10%

    2 Hem Saw Computer Stack Board

    All of these had CAPs POOF

    You might check to see what's used in laser cutters (find manuals/parts lists). It's hard to imagine that they would "cheap out" on the laser in such a device!

      I have read that the run time is about 30 minutes at a time because of over heating issues this is one reason for this post and other issues that I might not have considered or do not know about

        I can't speak to the time involved...

        The local makerhouse is currently having their laser repaired. One of the action items is to "add water cooling" (!) I think their's is 70W.

        But, I have no idea how the failure came about -- misuse? overuse? bad luck??
