@Aaron.F …Thank you

Nicky, your work is the finest I have ever seen !! Now for a tech question. What is difference between a $100 5W. laser and your 5W laser? I’m trying to justify the cost of your laser for another build project in the back of my mind. Thank you, Randy

His nearly $1k diode laser module has an adjustable spot size. The smallest spot is <50 microns, about that of my fiber.

The 423dpi … you can only do that effectively with a spot size of 0.06mm or less.

Not to mention he must have infinite patience. :face_with_spiral_eyes:

Yep, he has infinite patience.

This is a Hand Crafted Laser made in Poland
Almost 1/3 price is the High Quality Lens
The beam is 30 x 40 microns at 5 TRUE watts gives an incredible Laser Fluence
With a beam that small the Laser Machine /controller MUST be fine tuned and 0.9 Steppers are a must with TMC 2209 stepper boards
And a USB scope is a must to calibrate machine

Not sure what to say other than WOW !!!

Do you have any idea of the depth of focus on that lens or it’s focal length?


Pretty incredible on a piece of rice and the spaghetti. In comparison, my small engraving can’t hold a candle to yours.

Thanks for the explanation…

That’s pretty incredible… even with 500mW…

Thank you

Tried rice once with a “normal” 10W diode, more black burn than engrave.
Really nice.
