Thanks for the demo! Regarding cleaning, my own experiments have shown that water raises the woodgrain. Household ammomina disolves the smoke stain almost instantly and won't raise the grain. Coupled with a bristle brush it will clean the engraving. Alcohol will clean it also, just much slower.

[@TrotecLaser]

Thank you for the tip!

[@zina6581]

Makes sense, Thank you!!

[@jimashby3074]

Where can I find that 3D image. I’d like to try it out cal so I suppose you would use a soft bristle brush to clean after engraving?

[@TrotecLaser]

A soft bristle brush will work well to clean. Anything too abrasive and you may lose some of the finer details. Here is the design file! www.troteclaser.com/static/tlus-application-files/multi-pass-with-laser.zip

Your Ruby 400 laser is outside the scope of what I am looking at currently. Ideally this should work with a desktop CO2 laser as well, correct?

[@TrotecLaser]

This hack should work with other CO2 lasers!

Do you have any videos on producing a depth file image?

[@TrotecLaser]

We do not currently have a video showing the entire process, but we will keep it in mind for the future!

[@laserfalcon]

@@TrotecLaser I can make an image manually but is quite time consuming

[@nbraz2224]

@@TrotecLaser The process on how to make a 3D image file would be interesting. And very useful.

I have a Glowforge 45 watt Laser, much smaller then your 120 watt, What does the 1kh mean ? thank you :)

[@davidstevens2577]

1kh is a 1000 Hz frequency on the laser.

[@Mastroprimo]

This hack can work on metal engraving too ?

[@LaserItPro]

Yes, but only on certain fiber lasers that can sense the greyscale to mark deepest in the black point and fade power with the greyscale

[@0Turbox]

Does that also work with Acryl?

[@TrotecLaser]

Yes, this is possible with acrylic, but the effects will look different.

Hi I’m currently making a puzzle piece that requires multiple passes to cut through the wood. How can I get my laser (using light burn) to complete one passing before starting the next? It seems to do the circular pieces first multiple times.

[@glitter_fart]

play with the optimization settings or just disable them, you can preview the cut path before sending it to the machine, if that doesnt work just burn one pass at a time manually starting the 2nd/3rd etc

[@cjz1337]

@@glitter_fart thank you for your input! Appreciate the reply.

[@SantaDragon]

You said does not depent on material if it goes about depth, so this hack does not count for metal surface engraving?

[@TrotecLaser]

We cannot process depth into Metal with this machine.

Newb, researching the market before I plunge in. Isn't running any co2 laser at 100% a lifespan no-no? I guess if you are factoring laser replacement costs into the sale price of the item it could still work out with the increased speed being worth the wear and tear.

[@TrotecLaser]

With some brands, that is true. However, we use a ceramic core in our lasers. Because of this, they can easily handle full laser power whenever needed. Ceramic allows for better cooling, faster laser pulse time, and overall better performance, virtually eliminating the issues seen in other brands.

[@LaserItPro]

How do you automate the sequential laser passes?

[@TrotecLaser]

Hi! To automate the sequential laser passes, place a number of desired passes in the parameters of the color being used.

[@UltimateHeretic360]

​@@TrotecLaser what software are you using for this?

[@TrotecLaser]

@@UltimateHeretic360 We are using the Ruby software to run these applications.
