Great video! FYI this coupon code no longer gives you a price of $389, at least it doesn't for me. All it does is gives a flat $5 discount.

449 right now, i would have been a buyer at 389!! any ideas on discount? Thanks

@@Swalsh308............. ....... .

@@outragedpi3 $569 now. Amazing how fast they raise prices on everything with no justification. I can understand raising it like 20 or 30 bucks but 200 in 3 months is plain ridiculous. Price gouging at it's finest.

Hmmm.. I’ve found mixed reviews on how the limiter switch is actually suppose to go..according to ortur.tech/documentation/olm2pro/OLM2_Pro_User_Manual_EN.pdf The limiter is on the bottom of the plate so that the highest party of the wire will come into contact with the chassis. Sorry if this was already mentioned …you have a lot of comments to go through :D

So glad you enjoyed my video! :)

@@Schematix Hi ! Need to do the same job BUT on marble !! Guiding ideas please; or better: a video ... if possible Thank you so much for sharing !

Believe me, in the same price range, ortur will be better.

Exactly what I was thinking! I'm going to experiment with pcb etching using a laser to create the pcb mask

I’d get an CO2 laser. A large format will cost you $2k USD. This unit is only a 5.5 watt which is pretty underpowered. I think it can be done but you’ll need lots and lots of passes.

I can attest to the fact that it will not. I have never heard a good explanation as to white paint works better than black paint, but it does. I saw one video where a guy used cold galvanize paint. He said that worked way better than the white paint. However it is imperative you engrave outside or have a real good fume extractor because the burning cold galvanize paint puts off some really nasty, toxic fumes.

@@krisknowlton5935 That's strange to me. You would think it would remove the black paint as it does with the white. Thanks for responding.

@@JohnDoeTheTroll the tile is actually white and then you paint them with white paint. The laser burns the white paint turning it black making the engraved image. You cannot remove the image. You cannot scrape it of with any kind of sharp instrument. It is absolutely permanent. I have looked at the resulting image under a microscope and cannot tell you exactly what happens when the laser hits the white paint or why it works better than black paint. One would think black paint would absorb more of the light energy of the laser and make a darker image but I don't find that to be the case. In fact one would presuppose that white paint would not work at all as white objects tend to reflect the blue laser. It is even very hard to cut white paper with a blue laser. Coloured paper, no problem. There must be something in the white paint that absorbs the light energy of the laser. I'm usually pretty good at figuring out things but this has me stumped. It may be the titanium oxide in the paint but I just don't know.

You need to download the firmware before connecting to the computer, for more details on Ortur.net

You are correct. But all the videos I have seen you can't cut much more with K-40 lasers than this laser can. Also you can't engrave as big an area as this laser (with LightBurn you can engrave as big as you want with this laser because you can easily move the whole laser around ).kzfaq.info/get/bejne/pMWPpsSAsLzZoHU.html I currently have the LaserMaster 2 "15" watt laser and have done way more with it than I ever expected to. To me if it is a choice between the K-40 laser and the LaserMaster 2Pro for the same price...well...I purchased the LaserMaster 2 Pro. Another nice feature of the diode lasers is there is no mirror alignment or mirrors and lenses to replace. This is not a laser that you spend more time tweaking than engraving with. IMHO the LaserMaster 2 Pro is way more bang for the buck. By the way, I used to believe the same as you.
