Yes, as much as I like the idea of the JTech I can’t justify the cost of importing to the UK so it looks like the Ortur is a much better bet for me at present. Also in terms of space it will fit inside the area of an XXL when needed and store vertically on the wall when not.

I have the Jtech 4.2W kit on my XXL and really like it, the big selling point was it not taking up more space in our small basement. I got the version with the magnetic shroud, focusing is easy and the more safety the better. It works well for engraving, I haven’t tried cutting anything yet. Faster would be nice but not worth the extra space for getting a CO2 laser. I also like that the Jtech does seem to be built with safety in mind and isn’t just the cheapest laser that could be shipped from China.
I plan on making an enclosure for the Shapeoko with the windows made from laser safety acrylic, but haven’t gotten that done yet. Instead my first laser project was making a door knob hanger for the second pair of laser safety glasses. If it is hanging on the basement door knob my wife knows the laser is in use and to wear the glasses when coming down to the basement:
The laser does make a bit of smoke. I have a fan/air filter that will be installed on the enclosure but for now I just hang the 4" fan intake hose from the dust boot and it seems to take care of 90% of the smoke. Venting outside would be better, but is not trivial to do with our basement construction/layout.
I made a bunch of cedar plant name stakes for our backyard with it. You can get good detail on the lettering without the risk of chipping that comes from a Vbit. Each one takes about 10 minutes to engrave (60ipm, 100% power).

So, I’ve been looking into the Ortur Master 2 and it claims to support PWM. I wonder if it would be possible to remove the laser and relevant bits and mount/ connect it up to a Shapeoko and the CM board?
Edit: There is also this: https://www.banggood.com/New-NEJE-Master-2-Desktop-CNC-Wood-Router-20W-Laser-Engraver-Cutter-Laser-Engraving-Machine-APP-Control-for-Windows-or-Mac-or-Android-p-1678509.html?rmmds=search&cur_warehouse=CN
It has some unique protection built in such as “In NEJE mode, NEJE has intelligent detection protection to prevent accidental touch of household pets.” Which is always good to have! 
Edit 2: OMG I was messing with the Gearbest site on the Ortur page and my hand slipped and it went into my basket without me knowing and when I hit return, I don’t know but I think I just bought it! 
So I guess we’ll have to see.

Wait, I have been looking at J Tech’s stuff for years…(thought it was too pricy), and you saying that Ortur makes an ENTIRE machine (with a cough cough 20W Laser) delivered to my door for under $300 doll hairs?
SOLD!
PS $296.04 Total

Well, its cheap for a reason so buyer beware.
That said check this out; https://www.youtube.com/watch?v=HicoeqAgMck&list=UUKeRRN0BZzWrmamVAQUME2Q&index=7&t=1699s

Do you really think they (laser) is made by different little hands in China? (99.999 the same as J Tech’s Chinese Laser IMO)
True, it’s Chinese quality…that I understand…but for as much as I’m going to use it…like my Chinesium 3D Printer…it’s be more then fine…
One other thing on laser safety: fume extraction. When you cut something with a laser, it can give off some really nasty byproducts. ABS plastic for example produces hydrogen cyanide when cut, which can kill you by shutting down your respiratory system and it can cause explosions.
You should look at materials lists like this one to get an idea of which materials to cut but keep in mind that even these lists are made for laser cutters that operate inside a sealed enclosure with a filtered fume extractor taking care of the exhaust.
I’d strongly recommend that for any laser cutting, even of safe materials, you build an enclosure and direct the exhaust somewhere other than your lungs.

For the record, I get no commission on what looks like the TWO Orturs I just sold… MarkLince, RichCournoyer, would like to hear your experiences, though

You mean, you own the company - so there’s no commission involved?

I just got a “7W” NEJE. Need to make an easy way to connect everything, but I made a mount a couple nights ago.
I’ll try to remember to post back here if I ever get a chance to play with it.

That looks really cool, so that’s just the laser. I was thinking about that. In the end I opted for the Ortur Master 2 complete. My thinking is to have some sort of dual mount on and off the Shapeoko … maybe. I may need to pick your brains.
I’m not an engineer…so maybe one of you engineers will comment on the feasibility…but I wonder why no one has created a laser that mounts in the collet. The guts and diode could be external and piped into the stem on a fiber optic line…then the lens would be at the bottom of the stem. Chuck it in the collet and go. Feasible?
Jtech has one I think, a collet mounted laser I mean
I didn’t see it, for certain.
Well…there ya go! I wonder now why they don’t make this available as their Shapeoko kit
I think it might be a z travel thing, not sure.
Yup. After my first, router-replacing, test design, I read the description and realized the focal range is only like 10mm. There’s no controller or “test module” with the laser I got. I’ll have to figure out how to focus it.
This was my test mount. The clamping one in my previous post is the one I’ll actually use (I think… Haven’t tried the laser other than just proving that it works)
I built a little drawing robot and attached a laser to it, but the SO3 is so much more rigid.

Here is a mount I designed and printed for my spindle that I can easily slip on and off. I don’t like having the permanently mounted one, it seems to get in the way.
The ring is tight and has a gap in the back to slip around the connector and hoses.

I have a k40 CO2 laser that was mentioned. It’s a great little laser that can cut through up to around 6mm plywood or acrylic. For what it is I can’t fault it, but the bed is only 8x12", with no way to tile, or fit anything bigger than the bed.
If you’re only interested in laser engraving things, I’d definitely recommend the j-tech option or similar.
If you want to cut small objects like keyrings, plaques, coasters etc then the k40 is a great option, I have paid it off several times over in 6months or so, and I don’t even run a business

Ok, will do…it should arrive in a few months…
