This video demonstrates cnc engraving on wood. Both photo’s and pictures are being engraved by a 0.7Watt 445nm diode laser mounted on a CNC-Step High-Z S400 cnc machine.
Total engraving time in this video is 2u15 , but by optimising the lasing algorithm (skipping the white parts left and right of tigerhead) the process could be sped up to 1u30.
The laser engraves around 35 dots per second (7mm/sec) and each dot is about 0.2 x 0.2 mm.
Its not SUPERfast, but compare this less then $200 add-on with a $5000 laser engraver and you’ll understand why its slower. Conventional laser engravers use 40 or 60 watt co-2 laser tubes costing +$800 and only have about 1000 hours of burning time. This diode should have between 15000 and 20000 hours.
The cnc and laser-steering is done with an arduino microcontroller because I needed very tight timings in millisecond resolution to turn the laser on or off. Conventional milling controllers are mostly not that tight if you want to use spindle control, because they power on spindle and then give it time to spin up. If you would do that with laser, then you would get nice big burnt spots. The dots in this video all take 12 milliseconds / piece. So around 42% of time machine is burning dots and in 58% of time it is moving.

I have 2-3 times faster laser and its only 12-13 dots per second…
Hi, are you getting the PWM signal from the Hogh-Z ? Usually the Laser driver boards do only work with 0 – 5Volt PWM and I can only see the High-Z is having 0 – 10Volt Analog output. Have you converted that to 0 – 5Volt PWM? or did you use a breakout board?
Can you look at the dot a laser engraver makes WITH goggles on (to focus the beam, for example? Everything I read seems to suggest you can't look at the dot even with eye protection.
you have an interesting channel
Really nice video ! Great to see what youve all done with our cnc router machine 🙂

Thanks for the video!
Could you say more about this CNC? What is your recording area; she writes on glass, acrylic and she cuts? What's your price? Thank you
good job!! what software is used to engrave with the laser?
Ok does and im sure it dos hook up to a computer so what other equipment do I need? and how much?
Hi what software did you use to generate the g code.?
que software usaste?
amazing machine
Hi, is there a tutorial on how to calculate the power of the laser?
And how did you create the plat file?
I'm working on a milling machine with some friends…and we already got safty glasses and laser diodes (~420nM, 1000mW). So what could you suggest us?
where did your get part
Very nice, do you use Mach3?
Appreciate if you could instruct me how to wiring Arduino board?
I can't imagine the amount of work, the result is phenomenal. I'm hoping to get started on a similar looking project soon, but ive gotta start with the laser diode first, and see how it integrates. All new to me.
Would you mind sharing an insight to a good laser supplier like yours? Thanks! great video.
what software did you use to generate the g-code?
i have an Arduino running Grbl and need a program to generate the code to fill in images. right now i can only generate outlines
can your machine engrave on acrylic?
