They're both Chinese.

LightObject is a US retailer of Chinese products. Their X7 is just renamed Trocen AWC708C unit. Shenzhen Trocen Automation Technology Co.,LTD

As to 'which is better', that...

The cyclone pulls most of the debris, but I use a lot of MDF and that stuff gets everywhere. I don't have a hepa filter.

Plus the CNC machine isn't the only woodworking tool in the shop. Hard to...

Cool, thanks. I had no idea MDF was so porous. I’ve found a sizing guide for a replacement vacuum pump and it described using a plain sheet of MDF. would 18mm be too thick?

And I guess sealing...

I’ve (almost) acquired an older Chinese CNC router - it’s been idle for about 4 years but I got it working pretty well after a few minutes. It’s only had a few hours use in the seven or so years...

Thanks 1Jumper, that looks exactly like what it is.

I suspect they left it so long with the water in it that the vanes have corroded onto the housing. Probably buggered now, but I guess all I need...

I’ve ‘acquired’ a few years old chine cnc router.

It has a vacuum bed made out of what looks like a hard plastic, about 50mm thick.

From what I gather this machine has only been run for a few...

But you do feel the need to tell others not to?

You get what you pay for from China: pay rock-bottom, get cheaply-made and problematic. Pay a little more and get a reliable machine. Pay a lot and...

So you don't agree with a free market? If people keep buying lasers from China, it's for a reason. They offer something US made lasers don't (or Austrian-made, in the case of Trotec). Certainly for...

If you are still having problems, the 220V laser/controller/power supply can be replaced with a same-spec 110V one - that would be my first move. Switched mode poqwer supplies are cheap - get...

If you haven't got your order in already, you might be waiting a bit longer than you anticipate. It's more than two years since they started taking orders and have shipped less than 100 units. They...

Some RTV silicone releases acetic acid while it cures, but not after it is cured. That can be enough to attack solder joints, however. You can choose 'neutral cure' RTV silicone which releases...

You said: "sure if you had the same spec performance should be close to the same , but the specs aren't anywhere near the same on a glass tube Chinese co2 laser compared to a metal tube western...

Further: the technology differences seem to be the biggest difference - a glass CO2 laser operates at such high voltages, changes in frequency via pulse are harder than with metal CO2 lasers. Hence...

...except where they are, with a commensurate price hike. You seem to be comparing fish and apples. If you have two machines of different specification, they will perform differently, regardless of...

Can you explain how it is that the Trotec and Epilog do better? I would have thought it was a combination of power and motion speed that would dictate how effective a machine was and if you have the...

Is MDF expensive in Croatia? Approximately how much would it cost to make a standard Joe's?

So you use Corel Photo-Paint?

Be as amused as you like, Corel isn't a bitmap editor. In my 'real world', I would see 100 copies of Photoshop to every copy of Corel. Go into any learning institute...

I don't have, nor need, a 500W laser. You're just being obstreperous.

While you can cut 3mm ply with a blue laser diode, its laborious. The OP asked what was a suitable laser to cut 1/4" ply, your...

Further: Corel isn't photo enhancement software, it's a vector editor. It's photo manipulation abilities are poor. They do bundle Corel Photo-Paint, but that because no one would ever pay money for...

Good choice! Just out of interest, what was your complete cost, incl tax, customs, shipping to your house, compared to the cost of the Pro?

I need a bigger machine - 1390 probably - but will...

That doesn't seem like a small issue, but rather a glaring, massive, obvious fufu.

The ambient temps in my workshop are about 25C before the sun comes up - can get to 35-40C on a 'good' day :)
...

Haven't you got that the wrong way round? Bitmaps don't scale without interpolation. Vectors scale infinitely, with no loss of detail.

I was commenting on how you take a vector, convert it to...

Looks like a windows problem with the language code. What is your language/region set to? It has nothing to do with going from 2D to rotary... something else happened in between, I suspect..
...

15-20C is what I aim for. I don't know if there is an optimum setting, but I've seen commercial ones run at 8C

The cooler you can run it, the more power it will put out.

The difference being, they are ACTUALLY shipping their products, not taking orders and having you wait with bated breath for the next status update.

Does anyone actually own a glowforge yet? I...

Yeah but, you can buy them off the shelf... they aren't 'special'.

I love the way you are ripping TL after you bought a demo model second-hand, but the local guy is given props, for no support, no...

Simple: don't use warped stock.

Seems like a lot of work, where editing the vector fill for the boat to a solid colour would take seconds and leave you with the original vector for cutting. Or... take a copy, bitmap it and lay it...

80w will be fine for thin ply. Given that your 80w rating is probably closer to 65w... they lie :)

I too am looking at a larger machine but I came to the conclusion that an enclosed machine with...

He's got three motors... I guess one is for height.
