A Product review of the Twotrees TS2 Laser engraver!
This has a huge bed size, z-axis control, and a massive 20W Laser head!
More interestingly, Laser manufacturers have been offering 1064nm Laser heads as well, that can engrave all metals! (but I have other plans for it :-) so subscribe!)

Rest assured that we are committed to continually improving our products and services to meet your needs better. Thank you for your support and trust in our brand.
You need better customer support. I have been trying to get help with the 1064 module for a week now
Get an air assits and that will help with the char at the edge ... it did for me
What was your speed and power for the different metals with the 1064nm module?
Great demo, Les! Very reasonably priced for such a useful piece of kit, as well. Shame about it not being up to cutting through PCB copper layers. I still want one, w/20W head (or CO2), + air assist & heightening column.
"It's good to want," as an old English mate of mine used to say.
Now, I have to see what you're planning to do with it.
😎
Thanks! It will penetrate the copper layer, but it seems to fill the gap with copper oxide (or perhaps splattered copper) so it is quite conductive across the gap. Admittedly I have not tried too hard. The reason I took the gig is the 1064nm module, I have 'plans' for it :-)
Do they sell any proper enclosure for this? I can't imagine every one who might come in the path of the reflected beam wearing suitable protection!
Yes they do, with ports for attaching ducting to remove fumes. They also sell another model the TS3 which is built into an enclosure.
How do you wire up IR module on the 20w, the instructions for mine are for 10w and I can't work out where to attach the 2 wires to main board
Hello! Great Review!
How is it with cutting "White" Foambord, Epp, Depron?
Thx
Looks like a great product but was kinda hoping it would cut some metals. hell I can't have everything I want ! great review Les....cheers.
Cutting metals usually requires a pulsed/fiber laser rather than a lens-focused diode laser.
edit: made this comment before seeing the pulsed laser, quite curious to see they have both options, I wonder if the IR pulsed module is unable to sustain long enough duty cycles for cutting, then?
@@StormBurnX yes my thoughts too !
@StormBurnX and @andymouse123, It will cut Aluminium Foil, the kind you use in your kitchen (note the piece of aluminium foil in the bottom left of the frame at 17:00 with a 15mm hole in it!) It wasn't included in the video because it was already long enough.
The job was successful, but I need to build a Jig to hold the foil flat.
@@LesLaboratory Would be curious to note how many layers it can cut through (not truly analogous for metal thickness but still interesting)
I've seen some use to remove the resist from a PCB for later chemical etching to remove the resist ablated areas copper.
Another idea that caught my attention for if I ever need to cut metal that can be plasma cut, is using one of these cheap belt driven designed models with a plasma cutter mounted along with other design considerations like dealing with interference from all the noise. Joshua De Lisle youtube channel inspired that, what appears to be most cost effective CNC method.
It is something worth pursuing. I think Marco Reps had a go at that, with some reasonable success. It would be nice if a way could be found to just quickly etch off the copper though.
It would be interesting to see if this laser is able to perform Bayer filter removal?
I suspect 1064nm will either etch the silicon, or couple into the photodiodes, but it is worth investigating in any case.
Does anyone use other gasses in the air assist line? The copper would look rather different etched under an inert gas.
A little googling leads to:
_Different colors of iron oxide depend upon the oxidative state of the iron atom, with Fe+3 appearing brown and Fe+2 appearing red. Different colors of iron oxide also depend upon the amount of water added to the iron atom (iron hydroxides). This variation gives rise to the yellow, red, brown, and black colors._
Which suggests that control of humidity and oxygen content might lead to color etching.
Obviously excessive levels of oxygen or humidity will damage the engraver. I am not suggesting anyone try this, I am just curious if anyone has already come up with recipes that don't damage the laser cutter.
I suspect that with copper and iron, whatever color you get will quickly change on exposure to air. Some oxides will only survive in a dry or inert environment. On the other hand, aluminum(?), titanium, niobium, etc., have stable oxides and can be turned different colors depending on the temperature/laser intensity. Interesting idea though, it could be worth a try.
@@WaffleStaffel [edit: hit post instead of cancel. Ignore the previous version, it was wrong.]
Yes, only some of those compounds will be stable, but the ability to use a second color for emphasis would be cool.
Why does no one ever test the claimed specs? I mean the simplest thing to test would be the beam width. 0.08mm with stacked diodes at 20W, yeah right (maybe in one axis with an oval beam but no way 0.08mm square). With that said, maybe this one is better which is why I wish people would do real reviews and actually test/measure them.
So the 1064 is only for engraving metals? It's not for cutting anything?
Yup, just for engraving. It will cut very thin Aluminum foil which I have uses for...
Does anybody have recommendations for a cheapish laser that can mark metals and has no-touch autofocus?
Thanks!
Breaking Taps has done a few videos using a galvo scanner fiber laser that's about $750, if I recall correctly th-cam.com/video/TrYhy8Pll-0/w-d-xo.html
Hello, Do you know if it is capable of engraving in gold and silver? ty
@@viademontejewelry1032 I have not tried but it should do.
@@LesLaboratory It would be nice if you could do a small test in silver, I am looking at a machine like yours but I don't know if I should buy it for this reason. ty
Why dont you show the process of assemble?
Links are now 403
Anybody else hear the infuriating buzzing noise in the background? ruins the video up to about 2 mins 20 seconds. Still watching so I'm hoping it doesn't come back.
Weird, I don't hear it. Is it a high or low pitch?
@@LesLaboratory Not too annoying for me, but I definitely heard it. Using my phone as a spectrometer, seems like the fundamentals are at ~850Hz and ~1250Hz.
@@Xiaotian_Guan and @H3liosphan ah, ok, I have an idea what this is, it's either the radio mic or the camera pre-amp. I had to do some noise reduction in post, but seemingly I did not get it all. Time to invest in a separate voice recorder....
