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

[sam_sam_sam]

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

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??
